[mpich-discuss] Can I run MPI program without mpirun/mpiexec?

[Mário Costa]

Hi,

I have never done it but, I would say try it with mpiexec and print
the arv/arc contents then use the values sent by mpiexec to initialize
them inside your code, then pass them to MPI_Init()  ...

Let me know if it works ....

Regards,
Mário
