-McKernel new features, improvements and changes
------------------------------------------------
-1. McKernel and Linux share one unified kernel virtual address space.
-   That is, McKernel sections resides in Linux sections spared for
-   modules.  In this way, Linux can access the McKernel kernel memory
-   area.
-2. hugetlbfs support
-3. IHK is now included as a git submodule
-4. Debug messages are turned on/off in per souce file basis at run-time.
-5. It's prohibited for McKernel to access physical memory ranges which
-   Linux didn't give to McKernel.
-6. UTI (capability to spawn a thread on Linux CPU) improvement:

-===========================================
-What's new in V1.5.1 (July 9, 2018)
-===========================================
-
------------------------------------------------
-McKernel new features, improvements and changes
------------------------------------------------
-1. Watchdog timer to detect hang of McKernel
-   mcexec prints out the following line to its stderr when a hang of
-   McKernel is detected.
-
-       mcexec detected hang of McKernel
-
-   The watchdog timer is enabled by passing -i <timeout_in_sec> option
-   to mcreboot.sh. <timeout_in_sec> specifies the interval of checking
-   if McKernel is alive.
-   Example: mcreboot.sh -i 600: Detect the hang with 10 minutes interval
-
-   The detailed step of the hang detection is as follows.
-   (1) mcexec acquires eventfd for notification from IHK and perform
-       epoll() on it.
-   (2) A daemon called ihkmond monitors the state of McKernel periodically
-       with the interval specified by the -i option. It judges that
-       McKernel is hanging and notifies mcexec by the eventfd if its
-       state hasn't changed since the last check.
-
-2. Documentation
-   man page: Installed directory is changed to <install_dir>/share/man

---------------------
-McKernel workarounds
---------------------
-1. Forbid CPU oversubscription
-   * It can be turned on by mcreboot.sh -O option
-
-
-===================================
-What's new in V1.4.0 (Oct 30, 2017)
-===================================
-
------------------------------------------------------------
-Feature: Abstracted event type support in perf_event_open()
------------------------------------------------------------
-PERF_TYPE_HARDWARE and PERF_TYPE_CACHE types are supported.
-
-----------------------------------
-Clean-up: Direct user-space access
-----------------------------------
-Code lines using direct user-space access (e.g. passing user-space
-pointer to memcpy()) becomes more portable across processor
-architectures. The modification follows the following rules.
-
-1. Move the code section as it is to the architecture dependent
-   directory if it is a part of the critical-path.
-2. Otherwise, rewrite the code section by using the portable methods.
-   The methods include copy_from_user(), copy_to_user(),
-   pte_get_phys() and phys_to_virt().
-
---------------------------------
-Test: MPI and OpenMP micro-bench
---------------------------------
-The performance figures of MPI and OpenMP primitives are compared with
-those of Linux by using Intel MPI Benchmarks and EPCC OpenMP Micro
-Benchmark.
-
-
-===================================
-What's new in V1.3.0 (Sep 30, 2017)
-===================================
-
---------------------
-Feature: Kernel dump
---------------------
-1. A dump level of "only kernel memory" is added.
-
-The following two levels are available now:
-   0: Dump all
-  24: Dump only kernel memory
-
-The dump level can be set by -d option in ihkosctl or the argument
-for ihk_os_makedumpfile(), as shown in the following examples:
-
-   Command:		ihkosctl 0 dump -d 24
-   Function call:	ihk_os_makedumpfile(0, NULL, 24, 0);
-
-2. Dump file is created when Linux panics.
-
-The dump level can be set by dump_level kernel argument, as shown in the
-following example:
-
-   ihkosctl 0 kargs "hidos dump_level=24"
-
-The IHK dump function is registered to panic_notifier_list when creating
-/dev/mcdX and called when Linux panics.
-
------------------------------
-Feature: Quick Process Launch
------------------------------
-
-MPI process launch time and some of the initialization time can be
-reduced in application consisting of multiple MPI programs which are
-launched in turn in the job script.
-
-The following two steps should be performed to use this feature:
-1. Replace mpiexec with ql_mpiexec_start and add some lines for
-   ql_mpiexec_finalize in the job script
-2. Modify the app so that it can repeat calculations and wait for the
-   instructions from ql_mpiexec_{start,finalize} at the end of the
-   loop
-
-The first step is explained using an example. Assume the original job
-script looks like this:
-
-/* Execute ensamble simulation and then data assimilation, and repeat this
-   ten times */
-for i in {1..10}; do
-
-     /* Each ensamble simulation execution uses 100 nodes, launch ten of them
-        in parallel */
-    for j in {1..10}; do
-         mpiexec -n 100 -machinefile ./list1_$j p1.out a1 & pids[$i]=$!;
-    done
-
-    /* Wait until the ten ensamble simulation programs finish */
-    for j in {1..10}; do wait ${pids[$j]}; done
-
-    /* Launch one data assimilation program using 1000 nodes */
-    mpiexec -n 1000 -machinefile ./list2 p2.out a2
-done
-
-The job script should be modified like this:
-
-for i in {1..10}; do
-    for j in {1..10}; do
-        /*  Replace mpiexec with ql_mpiexec_start */
-        ql_mpiexec_start -n 100 -machinefile ./list1_$j p1.out a1 & pids[$j]=$!;
-    done
-
-    for j in {1..10}; do wait ${pids[$j]}; done
-
-    ql_mpiexec_start -n 1000 -machinefile ./list2 p2.out a2
-done
-
-/* p1.out and p2.out don't exit but are waiting for the next calculation.
-   So tell them to exit */
-for j in {1..10}; do
-   ql_mpiexec_finalize -machinefile ./list1_$i p1.out a1;
-done
-ql_mpiexec_finalize -machinefile ./list2 p2.out a2;
-
-
-The second step is explained using a pseudo-code.
-
-    MPI_Init();
-    Prepare data exchange with preceding / following MPI programs
-loop:
-    foreach Fortran module
-        Initialize data using command-line argments, parameter files,
-	environment variables
-    Input data from preceding MPI programs / Read snap-shot
-    Perform main calculation
-    Output data to following MPI programs / Write snap-shot
-    /* ql_client() waits for command of ql_mpiexec_{start,finish} */
-    if (ql_client() == QL_CONTINUE) { goto loop; }
-    MPI_Finalize();
-
-qlmpilib.h should be included in the code and libql{mpi,fort}.so
-should be linked to the executable file.
-
-
-========================
-Restrictions on McKernel
-========================
-
- 1. Pseudo devices such as /dev/mem and /dev/zero are not mmap()ed
-    correctly even if the mmap() returns a success. An access of their
-    mapping receives the SIGSEGV signal.
-
- 2. clone() supports only the following flags. All the other flags
-    cause clone() to return error or are simply ignored.
-
-    * CLONE_CHILD_CLEARTID
-    * CLONE_CHILD_SETTID
-    * CLONE_PARENT_SETTID
-    * CLONE_SETTLS
-    * CLONE_SIGHAND
-    * CLONE_VM
-
- 3. PAPI has the following restriction.
-
-    * Number of counters a user can use at the same time is up to the
-      number of the physical counters in the processor.
-
- 4. msync writes back only the modified pages mapped by the calling process.
-
- 5. The following syscalls always return the ENOSYS error.
-
-    * migrate_pages()
-    * move_pages()
-    * set_robust_list()
-
- 6. The following syscalls always return the EOPNOTSUPP error.
-
-    * arch_prctl(ARCH_SET_GS)
-    * signalfd()
-
- 7. signalfd4() returns a fd, but signal is not notified through the
-    fd.
-
- 8. set_rlimit sets the limit values but they are not enforced.
-
- 9. Address randomization is not supported.
-
-10. brk() extends the heap more than requestd when -h
-    (--extend-heap-by=)<step> option of mcexec is used with the value
-    larger than 4 KiB.  syscall_pwrite02 of LTP would fail for this
-    reason. This is because the test expects that the end of the heap
-    is set to the same address as the argument of sbrk() and expects a
-    segmentation violation occurs when it tries to access the memory
-    area right next to the boundary. However, the optimization sets
-    the end to a value larger than the requested. Therefore, the
-    expected segmentation violation doesn't occur.
-
-11. setpriority()/getpriority() won't work. They might set/get the
-    priority of a random mcexec thread. This is because there's no
-    fixed correspondence between a McKernel thread which issues the
-    system call and a mcexec thread which handles the offload request.
-
-12. mbind() can set the policy but it is not used when allocating
-    physical pages.
-
-13. MPOL_F_RELATIVE_NODES and MPOL_INTERLEAVE flags for
-    set_mempolicy()/mbind() are not supported.
-
-14. The MPOL_BIND policy for set_mempolicy()/mbind() works as the same
-    as the MPOL_PREFERRED policy. That is, the physical page allocator
-    doesn't give up the allocation when the specified nodes are
-    running out of pages but continues to search pages in the other
-    nodes.
-
-15. Kernel dump on Linux panic requires Linux kernel CentOS-7.4 and
-    later. In addition, crash_kexec_post_notifiers kernel argument
-    must be given to Linux kernel.
-
-16. setfsuid()/setfsgid() cannot change the id of the calling thread.
-    Instead, it changes that of the mcexec worker thread which takes
-    the system-call offload request.
-
-17. mmap (hugeTLBfs): The physical pages corresponding to a map are
-    released when no McKernel process exist. The next map gets fresh
-    physical pages.
-
-18. Sticky bit on executable file has no effect.
-
-19. Linux (RHEL-7 for x86_64) could hang when offlining CPUs in the
-    process of booting McKernel due to the Linux bug, found in
-    Linux-3.10 and fixed in the later version.  One way to circumvent
-    this is to always assign the same CPU set to McKernel.
-
-20. madvise:
-    * MADV_HWPOISON and MADV_SOFT_OFFLINE always returns -EPERM.
-    * MADV_MERGEABLE and MADV_UNMERGEABLE always returns -EINVAL.
-    * MADV_HUGEPAGE and MADV_NOHUGEPAGE on file map returns -EINVAL
-      (It succeeds on RHEL-8 for aarch64).
-
-21. brk() and mmap() doesn't report out-of-memory through its return
-    value. Instead, page-fault reports the error.
-
-22. Anonymous mmap pre-maps requested number of pages when contiguous
-    pages are available. Demand paging is used when not available.
-
-23. Mixing page sizes in anonymous shared mapping is not allowed. mmap
-    creates vm_range with one page size. And munmap or mremap that
-    needs the reduced page size changes the sizes of all the pages of
-    the vm_range.
-
-24. ihk_os_getperfevent() could time-out when invoked from Fujitsu TCS
-    (job-scheduler).
-
-25. The behaviors of madvise and mbind are changed to do nothing and
-    report success as a workaround for Fugaku.
-
-26. mmap() allows unlimited overcommit. Note that it corresponds to
-    setting sysctl ``vm.overcommit_memory`` to 1.

--------------------------
-
-IHK/McKernel is a light-weight multi-kernel operating system designed for high-end supercomputing. It runs Linux and McKernel, a light-weight kernel (LWK), side-by-side inside compute nodes and aims at the following:
-
-- Provide scalable and consistent execution of large-scale parallel scientific applications, but at the same time maintain the ability to rapidly adapt to new hardware features and emerging programming models
-- Provide efficient memory and device management so that resource contention and data movement are minimized at the system level
-- Eliminate OS noise by isolating OS services in Linux and provide jitter free execution on the LWK
-- Support the full POSIX/Linux APIs by selectively offloading (slow-path) system calls to Linux

-## Background and Motivation
-
-With the growing complexity of high-end supercomputers, the current system software stack faces significant challenges as we move forward to exascale and beyond. The necessity to deal with extreme degree of parallelism, heterogeneous architectures, multiple levels of memory hierarchy, power constraints, etc., advocates operating systems that can rapidly adapt to new hardware requirements, and that can support novel programming paradigms and runtime systems. On the other hand, a new class of more dynamic and complex applications are also on the horizon, with an increasing demand for application constructs such as in-situ analysis, workflows, elaborate monitoring and performance tools. This complexity relies not only on the rich features of POSIX, but also on the Linux APIs (such as the */proc*, */sys* filesystems, etc.) in particular.
-
-
-##### Two Traditional HPC OS Approaches
-
-Traditionally, light-weight operating systems specialized for HPC followed two approaches to tackle scalable execution of large-scale applications. In the full weight kernel (FWK) approach, a full Linux environment is taken as the basis, and features that inhibit attaining HPC scalability are removed, i.e., making it light-weight. The pure light-weight kernel (LWK) approach, on the other hand, starts from scratch and effort is undertaken to add sufficient functionality so that it provides a familiar API, typically something close to that of a general purpose OS, while at the same time it retains the desired scalability and reliability attributes. Neither of these approaches yields a fully Linux compatible environment.
-
-
-##### The Multi-kernel Approach
-
-A hybrid approach recognized recently by the system software community is to run Linux simultaneously with a lightweight kernel on compute nodes and multiple research projects are now pursuing this direction. The basic idea is that simulations run on an HPC tailored lightweight kernel, ensuring the necessary isolation for noiseless execution of parallel applications, but Linux is leveraged so that the full POSIX API is supported. Additionally, the small code base of the LWK can also facilitate rapid prototyping for new, exotic hardware features. Nevertheless, the questions of how to share node resources between the two types of kernels, where do device drivers execute, how exactly do the two kernels interact with each other and to what extent are they integrated, remain subjects of ongoing debate.
-
-
-
-## Architectural Overview
-
-At the heart of the stack is a low-level software infrastructure called Interface for Heterogeneous Kernels (IHK). IHK is a general framework that provides capabilities for partitioning resources in a many-core environment (e.g.,CPU cores and physical memory) and it enables management of lightweight kernels. IHK can allocate and release host resources dynamically and no reboot of the host machine is required when altering configuration. IHK also provides a low-level inter-kernel messaging infrastructure, called the Inter-Kernel Communication (IKC) layer. An architectural overview of the main system components is shown below.
-
-
-![arch](https://www.sys.r-ccs.riken.jp/members_files/bgerofi/mckernel.png)
-
-
-McKernel is a lightweight kernel written from scratch. It is designed for HPC and is booted from IHK. McKernel retains a binary compatible ABI with Linux, however, it implements only a small set of performance sensitive system calls and the rest are offloaded to Linux. Specifically, McKernel has its own memory management, it supports processes and multi-threading with a simple round-robin cooperative (tick-less) scheduler, and it implements signaling. It also allows inter-process memory mappings and it provides interfaces to hardware performance counters.
-
-### Functionality
-
-An overview of some of the principal functionalities of the IHK/McKernel stack is provided below.
-
-#### System Call Offloading
-
-System call forwarding in McKernel is implemented as follows. When an offloaded system call occurs, McKernel marshals the system call number along with its arguments and sends a message to Linux via a dedicated IKC channel. The corresponding proxy process running on Linux is by default waiting for system call requests through an ioctl() call into IHK’s system call delegator kernel module. The delegator kernel module’s IKC interrupt handler wakes up the proxy process, which returns to userspace and simply invokes the requested system call. Once it obtains the return value, it instructs the delegator module to send the result back to McKernel, which subsequently passes the value to user-space.
-
-#### Unified Address Space
-
-The unified address space model in IHK/McKernel ensures that offloaded system calls can seamlessly resolve arguments even in case of pointers. This mechanism is depicted below and is implemented as follows.
-
-
-![unified_ap](https://www.sys.r-ccs.riken.jp/members_files/bgerofi/img/unified_address_space_en.png)
-
-
-First, the proxy process is compiled as a position independent binary, which enables us to map the code and data segments specific to the proxy process to an address range which is explicitly excluded from McKernel’s user space. The grey box on the right side of the figure demonstrates the excluded region. Second, the entire valid virtual address range of McKernel’s application user-space is covered by a special mapping in the proxy process for which we use a pseudo file mapping in Linux. This mapping is indicated by the blue box on the left side of the figure.
-
-
-## Installation

+
+Watchdog timer to detect hang of McKernel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+mcexec prints out the following line to its stderr when a hang of McKernel is detected.
+
+::
+   
+       mcexec detected hang of McKernel
+
+The watchdog timer is enabled by passing -i <timeout_in_sec> option to mcreboot.sh. <timeout_in_sec> specifies the interval of checking if McKernel is alive.
+
+For example, specify ``-i 600`` to detect the hang with 10 minutes interval:
+
+::
+
+   mcreboot.sh -i 600
+
+The detailed step of the hang detection is as follows.
+   #. mcexec acquires eventfd for notification from IHK and perform epoll() on it.
+   #. A daemon called ihkmond monitors the state of McKernel periodically with the interval specified by the -i option. It judges that McKernel is hanging and notifies mcexec by the eventfd if its state hasn't changed since the last check.

+Direct user-space access
+----------------------------------
+Code lines using direct user-space access (e.g. passing user-space
+pointer to memcpy()) becomes more portable across processor
+architectures. The modification follows the following rules.
+
+1. Move the code section as it is to the architecture dependent
+   directory if it is a part of the critical-path.
+2. Otherwise, rewrite the code section by using the portable methods.
+   The methods include copy_from_user(), copy_to_user(),
+   pte_get_phys() and phys_to_virt().

+===================================
+Version 1.3.0 (Sep 30, 2017)
+===================================
+
+--------------------
+Kernel dump
+--------------------
+#. A dump level of "only kernel memory" is added.
+
+The following two levels are available now:
+
++--+-----------------------+
+| 0|Dump all               |
++--+-----------------------+
+|24|Dump only kernel memory|
++--+-----------------------+
+
+The dump level can be set by -d option in ihkosctl or the argument
+for ihk_os_makedumpfile(), as shown in the following examples:
+
+::
+
+   Command:		ihkosctl 0 dump -d 24
+   Function call:	ihk_os_makedumpfile(0, NULL, 24, 0);
+
+#. Dump file is created when Linux panics.
+
+The dump level can be set by dump_level kernel argument, as shown in the
+following example:
+
+::
+
+   ihkosctl 0 kargs "hidos dump_level=24"
+
+The IHK dump function is registered to panic_notifier_list when creating /dev/mcdX and called when Linux panics.
+
+-----------------------------
+Quick Process Launch
+-----------------------------
+
+MPI process launch time and some of the initialization time can be
+reduced in application consisting of multiple MPI programs which are
+launched in turn in the job script.
+
+The following two steps should be performed to use this feature:
+#. Replace mpiexec with ql_mpiexec_start and add some lines for ql_mpiexec_finalize in the job script
+#. Modify the app so that it can repeat calculations and wait for the instructions from ql_mpiexec_{start,finalize} at the end of the loop
+
+The first step is explained using an example. Assume the original job script looks like this:
+
+.. code-block:: none
+   
+   /* Execute ensamble simulation and then data assimilation, and repeat this ten times */
+   for i in {1..10}; do
+   
+      /* Each ensamble simulation execution uses 100 nodes, launch ten of them in parallel */
+      for j in {1..10}; do
+         mpiexec -n 100 -machinefile ./list1_$j p1.out a1 & pids[$i]=$!;
+      done
+
+      /* Wait until the ten ensamble simulation programs finish */
+      for j in {1..10}; do wait ${pids[$j]}; done
+      
+      /* Launch one data assimilation program using 1000 nodes */
+      mpiexec -n 1000 -machinefile ./list2 p2.out a2
+   done
+   
+The job script should be modified like this:
+
+.. code-block:: none
+
+   for i in {1..10}; do
+      for j in {1..10}; do
+         /*  Replace mpiexec with ql_mpiexec_start */
+         ql_mpiexec_start -n 100 -machinefile ./list1_$j p1.out a1 & pids[$j]=$!;
+      done
+      
+      for j in {1..10}; do wait ${pids[$j]}; done
+      
+      ql_mpiexec_start -n 1000 -machinefile ./list2 p2.out a2
+   done
+   
+   /* p1.out and p2.out don't exit but are waiting for the next calculation. So tell them to exit */
+   for j in {1..10}; do
+      ql_mpiexec_finalize -machinefile ./list1_$i p1.out a1;
+   done
+   
+   ql_mpiexec_finalize -machinefile ./list2 p2.out a2;
+
+The second step is explained using a pseudo-code.
+
+.. code-block:: none
+
+   MPI_Init();
+   Prepare data exchange with preceding / following MPI programs
+   loop:
+   foreach Fortran module
+      Initialize data using command-line argments, parameter files, environment variables
+      Input data from preceding MPI programs / Read snap-shot
+      Perform main calculation
+      Output data to following MPI programs / Write snap-shot
+      /* ql_client() waits for command of ql_mpiexec_{start,finish} */
+      if (ql_client() == QL_CONTINUE) { goto loop; }
+      MPI_Finalize();
+
+qlmpilib.h should be included in the code and libql{mpi,fort}.so should be linked to the executable file.

+Architectural Overview
+======================
+
+At the heart of the stack is a low-level software infrastructure called
+Interface for Heterogeneous Kernels (IHK). IHK is a general framework
+that provides capabilities for partitioning resources in a many-core
+environment (e.g.,CPU cores and physical memory) and it enables
+management of lightweight kernels. IHK can allocate and release host
+resources dynamically and no reboot of the host machine is required when
+altering configuration. IHK also provides a low-level inter-kernel
+messaging infrastructure, called the Inter-Kernel Communication (IKC)
+layer. An architectural overview of the main system components is shown
+below.
+
+.. figure:: mckernel.png
+   :alt: arch
+
+McKernel is a lightweight kernel written from scratch. It is designed
+for HPC and is booted from IHK. McKernel retains a binary compatible ABI
+with Linux, however, it implements only a small set of performance
+sensitive system calls and the rest are offloaded to Linux.
+Specifically, McKernel has its own memory management, it supports
+processes and multi-threading with a simple round-robin cooperative
+(tick-less) scheduler, and it implements signaling. It also allows
+inter-process memory mappings and it provides interfaces to hardware
+performance counters.
+
+Functionality
+-------------
+
+An overview of some of the principal functionalities of the IHK/McKernel
+stack is provided below.
+
+System Call Offloading
+~~~~~~~~~~~~~~~~~~~~~~
+
+System call forwarding in McKernel is implemented as follows. When an
+offloaded system call occurs, McKernel marshals the system call number
+along with its arguments and sends a message to Linux via a dedicated
+IKC channel. The corresponding proxy process running on Linux is by
+default waiting for system call requests through an ioctl() call into
+IHK’s system call delegator kernel module. The delegator kernel module’s
+IKC interrupt handler wakes up the proxy process, which returns to
+userspace and simply invokes the requested system call. Once it obtains
+the return value, it instructs the delegator module to send the result
+back to McKernel, which subsequently passes the value to user-space.
+
+Unified Address Space
+~~~~~~~~~~~~~~~~~~~~~
+
+The unified address space model in IHK/McKernel ensures that offloaded
+system calls can seamlessly resolve arguments even in case of pointers.
+This mechanism is depicted below and is implemented as follows.
+
+.. figure:: unified_address_space_en.png
+   :alt: unified_ap
+
+First, the proxy process is compiled as a position independent binary,
+which enables us to map the code and data segments specific to the proxy
+process to an address range which is explicitly excluded from McKernel’s
+user space. The grey box on the right side of the figure demonstrates
+the excluded region. Second, the entire valid virtual address range of
+McKernel’s application user-space is covered by a special mapping in the
+proxy process for which we use a pseudo file mapping in Linux. This
+mapping is indicated by the blue box on the left side of the figure.

+Background and Motivation
+=========================
+
+With the growing complexity of high-end supercomputers, the current
+system software stack faces significant challenges as we move forward to
+exascale and beyond. The necessity to deal with extreme degree of
+parallelism, heterogeneous architectures, multiple levels of memory
+hierarchy, power constraints, etc., advocates operating systems that can
+rapidly adapt to new hardware requirements, and that can support novel
+programming paradigms and runtime systems. On the other hand, a new
+class of more dynamic and complex applications are also on the horizon,
+with an increasing demand for application constructs such as in-situ
+analysis, workflows, elaborate monitoring and performance tools. This
+complexity relies not only on the rich features of POSIX, but also on
+the Linux APIs (such as the */proc*, */sys* filesystems, etc.) in
+particular.
+
+Two Traditional HPC OS Approaches
+---------------------------------
+
+Traditionally, light-weight operating systems specialized for HPC
+followed two approaches to tackle scalable execution of large-scale
+applications. In the full weight kernel (FWK) approach, a full Linux
+environment is taken as the basis, and features that inhibit attaining
+HPC scalability are removed, i.e., making it light-weight. The pure
+light-weight kernel (LWK) approach, on the other hand, starts from
+scratch and effort is undertaken to add sufficient functionality so that
+it provides a familiar API, typically something close to that of a
+general purpose OS, while at the same time it retains the desired
+scalability and reliability attributes. Neither of these approaches
+yields a fully Linux compatible environment.
+
+The Multi-kernel Approach
+-------------------------
+
+A hybrid approach recognized recently by the system software community
+is to run Linux simultaneously with a lightweight kernel on compute
+nodes and multiple research projects are now pursuing this direction.
+The basic idea is that simulations run on an HPC tailored lightweight
+kernel, ensuring the necessary isolation for noiseless execution of
+parallel applications, but Linux is leveraged so that the full POSIX API
+is supported. Additionally, the small code base of the LWK can also
+facilitate rapid prototyping for new, exotic hardware features.
+Nevertheless, the questions of how to share node resources between the
+two types of kernels, where do device drivers execute, how exactly do
+the two kernels interact with each other and to what extent are they
+integrated, remain subjects of ongoing debate.

+"Traditionally, light-weight operating systems specialized for HPC "
+"followed two approaches to tackle scalable execution of large-scale "
+"applications. In the full weight kernel (FWK) approach, a full Linux "
+"environment is taken as the basis, and features that inhibit attaining "
+"HPC scalability are removed, i.e., making it light-weight. The pure "
+"light-weight kernel (LWK) approach, on the other hand, starts from "
+"scratch and effort is undertaken to add sufficient functionality so that "
+"it provides a familiar API, typically something close to that of a "
+"general purpose OS, while at the same time it retains the desired "

+"A hybrid approach recognized recently by the system software community is"
+" to run Linux simultaneously with a lightweight kernel on compute nodes "
+"and multiple research projects are now pursuing this direction. The basic"
+" idea is that simulations run on an HPC tailored lightweight kernel, "
+"ensuring the necessary isolation for noiseless execution of parallel "
+"applications, but Linux is leveraged so that the full POSIX API is "
+"supported. Additionally, the small code base of the LWK can also "
+"facilitate rapid prototyping for new, exotic hardware features. "
+"Nevertheless, the questions of how to share node resources between the "
+"two types of kernels, where do device drivers execute, how exactly do the"
+" two kernels interact with each other and to what extent are they "
+"integrated, remain subjects of ongoing debate."

+"McKernel is a lightweight kernel written from scratch. It is designed for"
+" HPC and is booted from IHK. McKernel retains a binary compatible ABI "
+"with Linux, however, it implements only a small set of performance "
+"sensitive system calls and the rest are offloaded to Linux. Specifically,"
+" McKernel has its own memory management, it supports processes and multi-"
+"threading with a simple round-robin cooperative (tick-less) scheduler, "
+"and it implements signaling. It also allows inter-process memory mappings"
+" and it provides interfaces to hardware performance counters."

+msgid ""
+"System call forwarding in McKernel is implemented as follows. When an "
+"offloaded system call occurs, McKernel marshals the system call number "
+"along with its arguments and sends a message to Linux via a dedicated IKC"
+" channel. The corresponding proxy process running on Linux is by default "
+"waiting for system call requests through an ioctl() call into IHK’s "
+"system call delegator kernel module. The delegator kernel module’s IKC "
+"interrupt handler wakes up the proxy process, which returns to userspace "
+"and simply invokes the requested system call. Once it obtains the return "
+"value, it instructs the delegator module to send the result back to "
+"McKernel, which subsequently passes the value to user-space."

+IHK/McKernel is a light-weight multi-kernel operating system designed
+for high-end supercomputing. It runs Linux and McKernel, a light-weight
+kernel (LWK), side-by-side inside compute nodes and aims at the
+following:
+
+-  Provide scalable and consistent execution of large-scale parallel
+   scientific applications, but at the same time maintain the ability to
+   rapidly adapt to new hardware features and emerging programming
+   models
+-  Provide efficient memory and device management so that resource
+   contention and data movement are minimized at the system level
+-  Eliminate OS noise by isolating OS services in Linux and provide
+   jitter free execution on the LWK
+-  Support the full POSIX/Linux APIs by selectively offloading
+   (slow-path) system calls to Linux

+Architectural Overview
+======================
+
+See `Quick Guide -- Architectural Overview <quick.html#architectural-overview>`__.
+
+Running Programs
+================
+
+You need to check if your application and pre-/post-processing programs are suited to run with McKernel.
+Follow the guide below to choose to run the whole on McKernel, or run the whole on Linux, or run pre-/post-processing on Linux and the application on McKernel:
+
+* Application
+
+  - Run the whole on Linux if it issues system calls frequently and becoming the bottleneck with McKernel, e.g., those performing many file I/O operations.
+  - Otherwise, run it on McKernel.
+
+* Pre-/Post-processing
+
+  - Run it on McKernel if it consumes a large amount of memory or the execution time isn't prolonged prohivitively with McKernel. The reason for the first condition is that the resource could be limited for Linux CPUs in the nodes for McKernel.
+  - Otherwise, run it on Linux.
+
+
+Modify job script
+-----------------
+
+When using job submission system, you need to modify the job scripts so that the job script itself is going to run on Linux.
+For example, with Fujitsu Technical Computing Suite (TCS), you need to specify ``jobenv=mck1`` by inserting the following line into the job script:
+
+.. code-block:: none
+
+   #PJM -L jobenv=mck1
+
+Insert ``mcexec`` into the command line
+---------------------------------------
+
+You need to insert ``mcexec`` into the command lines invoking the programs that you chose to run on McKernel:
+
+Non-MPI programs
+~~~~~~~~~~~~~~~~
+
+Insert ``mcexec`` before an executable:
+
+::
+
+   mcexec ./a.out
+
+MPI programs
+~~~~~~~~~~~~
+
+Insert ``mcexec -n <processes-per-node>`` **after mpirun** and before an
+executable:
+
+::
+
+   mpirun -n <number-of-MPI-processes> mcexec -n <processes-per-node> ./a.out
+
+``<processes-per-node>`` is the number of the processes per node and
+calculated by (number of MPI processes) / (number of nodes).
+
+For example, ``<processes-per-node>`` equals to 4 (=32/8) when
+specifying the number of processes and nodes as follows with
+Fujitsu Technical Computing Suite.
+
+.. code-block:: none
+
+   #PJM --mpi "proc=32"
+   #PJM -L "node=8"
+
+Limitations
+===========
+
+1.  Pseudo devices such as /dev/mem and /dev/zero are not mmap()ed
+    correctly even if the mmap() returns a success. An access of their
+    mapping receives the SIGSEGV signal.
+
+2.  clone() supports only the following flags. All the other flags cause
+    clone() to return error or are simply ignored.
+
+    -  CLONE_CHILD_CLEARTID
+    -  CLONE_CHILD_SETTID
+    -  CLONE_PARENT_SETTID
+    -  CLONE_SETTLS
+    -  CLONE_SIGHAND
+    -  CLONE_VM
+
+3.  PAPI has the following restriction.
+
+    -  Number of counters a user can use at the same time is up to the
+       number of the physical counters in the processor.
+
+4.  msync writes back only the modified pages mapped by the calling
+    process.
+
+5.  The following syscalls always return the ENOSYS error.
+
+    -  migrate_pages()
+    -  move_pages()
+    -  set_robust_list()
+
+6.  The following syscalls always return the EOPNOTSUPP error.
+
+    -  arch_prctl(ARCH_SET_GS)
+    -  signalfd()
+
+7.  signalfd4() returns a fd, but signal is not notified through the fd.
+
+8.  set_rlimit sets the limit values but they are not enforced.
+
+9.  Address randomization is not supported.
+
+10. brk() extends the heap more than requestd when -h (–extend-heap-by=)
+    option of mcexec is used with the value larger than 4 KiB.
+    syscall_pwrite02 of LTP would fail for this reason. This is because
+    the test expects that the end of the heap is set to the same address
+    as the argument of sbrk() and expects a segmentation violation
+    occurs when it tries to access the memory area right next to the
+    boundary. However, the optimization sets the end to a value larger
+    than the requested. Therefore, the expected segmentation violation
+    doesn’t occur.
+
+11. setpriority()/getpriority() won’t work. They might set/get the
+    priority of a random mcexec thread. This is because there’s no fixed
+    correspondence between a McKernel thread which issues the system
+    call and a mcexec thread which handles the offload request.
+
+12. mbind() can set the policy but it is not used when allocating
+    physical pages.
+
+13. MPOL_F_RELATIVE_NODES and MPOL_INTERLEAVE flags for
+    set_mempolicy()/mbind() are not supported.
+
+14. The MPOL_BIND policy for set_mempolicy()/mbind() works as the same
+    as the MPOL_PREFERRED policy. That is, the physical page allocator
+    doesn’t give up the allocation when the specified nodes are running
+    out of pages but continues to search pages in the other nodes.
+
+15. Kernel dump on Linux panic requires Linux kernel CentOS-7.4 and
+    later. In addition, crash_kexec_post_notifiers kernel argument must
+    be given to Linux kernel.
+
+16. setfsuid()/setfsgid() cannot change the id of the calling thread.
+    Instead, it changes that of the mcexec worker thread which takes the
+    system-call offload request.
+
+17. mmap (hugeTLBfs): The physical pages corresponding to a map are
+    released when no McKernel process exist. The next map gets fresh
+    physical pages.
+
+18. Sticky bit on executable file has no effect.
+
+19. Linux (RHEL-7 for x86_64) could hang when offlining CPUs in the
+    process of booting McKernel due to the Linux bug, found in
+    Linux-3.10 and fixed in the later version. One way to circumvent
+    this is to always assign the same CPU set to McKernel.
+
+20. madvise:
+
+    -  MADV_HWPOISON and MADV_SOFT_OFFLINE always returns -EPERM.
+    -  MADV_MERGEABLE and MADV_UNMERGEABLE always returns -EINVAL.
+    -  MADV_HUGEPAGE and MADV_NOHUGEPAGE on file map returns -EINVAL
+       except on RHEL-8 for aarch64.
+
+21. brk() and mmap() doesn’t report out-of-memory through its return
+    value. Instead, page-fault reports the error.
+
+22. Anonymous mmap pre-maps requested number of pages when contiguous
+    pages are available. Demand paging is used when not available.
+
+23. Mixing page sizes in anonymous shared mapping is not allowed. mmap
+    creates vm_range with one page size. And munmap or mremap that needs
+    the reduced page size changes the sizes of all the pages of the
+    vm_range.
+
+24. ihk_os_getperfevent() could time-out when invoked from Fujitsu TCS
+    (job-scheduler).
+
+25. The behaviors of madvise and mbind are changed to do nothing and
+    report success as a workaround for Fugaku.
+
+26. mmap() allows unlimited overcommit. Note that it corresponds to
+    setting sysctl ``vm.overcommit_memory`` to 1.
+
+27. mlockall() is not supported and returns -EPERM.
+
+28. munlockall() is not supported and returns zero.
+
+29. scheduling behavior is not Linux compatible. For example, sometimes one of the two processes on the same CPU continues to run after yielding.
