[Swift-user] task parallel MPI

[Justin M Wozniak]

Ok, it looks to me like some kind srun thing: you can look in the log at 
the GridExec lines to find out what was passed to your execmpi script. 
The -e argument is the executable and the -a argument is the executable 
arguments.  You may also try to capture more debugging information in the 
execmpi script itself.
