[mpich-discuss] MPI_Recv crashes with mpd ring

[Jain, Rohit]

I had:

set path = (<path_to_exec> $path) in my c-shell, which is equivalent of
$PATH.

It doesn't work for me.

Dave's suggestion of using `which a.exec` does work though.

Regards,
Rohit

If you have $PATH set in your working shell, Hydra should pick it up 
automatically. I'm assuming this is what you are doing:

% export PATH=<path_to_exec>:$PATH

% mpiexec.hydra -f hosts -n 1 a.exec arg1 : -n 1 a.exec arg2 : -n 1
a.exec arg3 : -n 1 a.exec arg4

I just tried this and it seems to work fine.
