[mpich-discuss] .pg files in mpich2

[Matthew Bettencourt]

That doesnt work, i want to run valgrind on Rank=0, what i used to do is 
create a .pg file and then run

valgrind options ./myjob

and rank0 would run through valgrind.

The same sort of thing, i could edit the myjob.pg file to run a script 
for one rank in particular

Thanks
M
