[mpich-discuss] MPICH 2 script to MPICH 3

19 Jan 2015

      Hello,
I have been using Htcondor with MPICH 2 but I update MPICH 2 to MPICH 3 and now the MPD process manager has been deprecated and Hydra is de default process manager. 
The script I was using use some commands like mpdtrace, mpdallexit but they are not supported anymore.
Here is my script, is it any possibility to change this script code to be able to work with Hydra?
Thank you very much,
Livan Valladares Martell
Script:

#!/bin/sh
