Hi Mikhail,
That's something you can achieve with Slurm, using what they call
Core Specialization. See http://slurm.schedmd.com/core_spec.html for
details.
Cheers,

Hi Mikhail,
I would guess your queueing system could take care of that.
With SGE you can define how many cores each node has. Thus, if you only want to
use 16 out of the 18 cores you simply define that.
Alternatively, at least OpenMPI allows you to underpopulate the nodes as well.
Having
New special supercomputer microprocessors (like IBM Power BQC and Fujitsu
SPARC64 XIfx) have 2**N +2 cores (N=4 for 1st, N=5 for 2nd), where 2 last cores
are redundant, not for computations, but only for other work w/Linux or even
for replacing of failed computational core.
Current Intel
The processor in the IBM BG/Q is actually a POWER A2.[1] I never
understood why Top500 listed them as BQC. The POWER A2 processor
actually has 18 cores: 16 for computations, 1 for the OS itself, and 1
'spare'. I believe the spare is not a hot spare, but is there to
increase the yield in chip

Current Intel Haswell E5 v3 may also have 18 = 2**4 +2 cores. Is there some
sense to try POWER BQC or SPARC64 XIfx ideas (not exactly), and use only 16
Haswell cores for parallel computations ? If the answer is yes, then how
to use this
