[mpich-discuss] mpiexec errors when running cpi

[Kelvin Wong]

Dear Pavan,

Yes, only these messages are shown and the command prompt is then returned. 

After trying to execute "locally" on both nodes, with accepting those SSH
authenticity of the hosts, and with login and logout the sessions, etc, it
now works! Yet I'm not so sure whether I'm done on the installation??

I shall see how I can re-produce it and then run with the verbose parm.

Regards,
Kelvin

Is the error message below complete? Can you also run mpiexec with -verbose
to send us the output?
