You can specify the number of processes per host like so: mpiexec -hosts host1:4,host2:2 -n 6 ./mytask On 08/12/2016 10:43 AM, Doha Ehab wrote:
Hello,
I am running mpi code on host1(quad core) and host2(dual core)
mpiexec -hosts host1,host2 -n 6 ./mytask
I want to assign 4 processes for host1 and 2 for host2. I tried --map-by core but I found that the processes are distributed 3 for each.
Regards Doha
