[mpich-discuss] Cannot use the main node to run a process of the programme

[Waruna Ranasinghe]

Hi,
I tried even mapping the drive as Jayesh mentioned, but the problem is still
the same.
If I run the programme only in the master node, then it will run. Otherwise
if I use other nodes including master node to run the programme, the
programme give the output but it won't exit (mpi finalize does not work or
called)

Please help me to over come this issue.

Regards,
Waruna Ranasinghe
