This is a response to a CEA's request.
- The tools directory is created under the mckernel directory.
- Some include files are now installed in the install directory,
but we should rethink of it.
- make should be $(MAKE)
- add + in front of rules spawning long-lasted make process in a
subshell. (This would not be needed with $(MAKE) -C .. target, but our
makefiles do not handle that because they use $(PWD))
- split the main 'all' rule as all 4 targets are independant
- fix dependencies where appropriate for parallelism
Extra, not speed-related changes:
- remove some double-colon for targets as they do not need it
This cuts build time from 5s to 1.5s on a laptop with -j4, and more
importantly from 85s to 35s on a KNL node.
As a bonus, the fixed dependencies removes the need to clean before
rebuilding all the time. Probably.
When rebooting:
1. Stop irqbalance
2. Modify /proc/irq/*/smp_affinity so that McKernel cores are not
included
3. Start irqbalance with McKernel cores and IHK IRQ banned from
load balancing
When stopping:
1. Stop irqbalance
2. Restore /proc/irq/*/smp_affinity
3. Restart irqbalance with the system default settings
refs #760
It decides the number of cores for McKernel by looking into the
"SHIMOS: CPU Status:" line of dmesg. It sets the amount of memory for
McKernel to one urth of the total memory obtained by "free -g".
