I think that you can do what you want if you use an appfile with something like this:
-host node1,node2,node3 -np 6 -wdir /WorkingDir/ appname
-host node4 -np 2 -wdir /DifferentWorkingDir/ appname
Then run your program using "mpirun --app appfilename".
Is there a way to specify different working directories for
different hosts ?. I mean for a single application launched
from one of them. Seems I can't do that in the hostfile ... :/.
Thanks in advance,
PS: I was unable to find the answer in the archives, sorry if
it's too trivial.
