[mpich-discuss] Not able to run MPI program parallely...

[Albert Spade]

Hi Pavan,

Thanks alot for your help.
Can you please tell me how can I recompile with this new mpiexec?? As in ui
folder  I found mpiexec.c and mpiexec.h.
So whether first I have to compile mpiexec.c and create mpiexec. And then
use this mpiexec to compile my cpi.c program?
Sorry for my simple query. I am new to the field of clusters and MPI.

Thanks again.
