+msgid ""
+"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."

+#: ../../archtecture.rst:18
+msgid ""
+"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 Offloading"
+msgstr ""
+
+#: ../../archtecture.rst:37
+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."

+msgid "Unified Address Space"
+msgstr ""
+
+#: ../../archtecture.rst:51
+msgid ""
+"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."
+msgstr ""
+
+#: ../../archtecture.rst:58
+msgid ""
+"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."
