equivalence of openmpi --cpu-set 0-15 in intel mpi
Using htop, I can see processors' states (idling or runnning jobs), and
some idea of the memory usage.
I have been using --cpu-set in openmpi quite a lot and it is very
easy to specify a range of cores
to use. 0-n means core numbered 0 to n will be
used, comma separated syntax is useful if we are patient enough
to type out a list such 1, 3, 5, 7.
Now, I have installed an applications under
mpi implemented by intel (the free high
performance tools from intel website).
Even though it is good to go deep into the computer architecture
to know how compute nodes are organized, but it seems I just
want to use the natural index (0 to n-1) to tell me where I want my MPI
jobs to run.
Is there a simple equivalence of --cpu-set in intel mpirun command?
--cpu-set syntax is really easy to use. As long as I know a little
bit about the socket/node/core/thread arrangement, I can always
come up with a set of numbers to specify which core to use.
Any idea?
