Dear all,

 

I am working on a shared memory processor with 256 cores. I am working from the command line directly.

 

Can I restict the number of cores that I deploy.The command

 

mpirun -n 100 myprog

 

 

will automatically start on 100 cores. I wish to use only 10 cores and have 10 threads on each core. Can I do this with mpich ?  Rememebre that this an smp abd I can not identify each core individually(as in a cluster)

 

Regards, bob
