OpenMPI Users,
I am using AMD processocers with CMT, where two cores constitute a
module, and there is only one FPU per module, so each pair of cores has
to share a single FPU. I want to use only one core per module so there
is no contention between cores in the same module for the single FPU. Is
this possible from the command-line using mpirun with the correct
binding specifications? If so, how would I do this?
I am using OpenMPI 1.10.3. I read the man page regarding the
bind-to-core options, and I'm not sure that will do exactly what I want,
so I figured I'd ask the experts here.
