Hello,
I have questions about MPICH jobs. Our site runs LCG2.3 on SL3 with the maui
scheduler and pbs.
- Does anybody know how to specify a NODENUMBER greater than the number of
WNs on a site, which has more than 1 CPU per WN? I want to use all available
CPUs (here: 2 CPUs per WN).
- How can I tell maui to reserve x nodes for me, but only one CPU per node?
In LCG2.2 times I specified nodenumber=x, then ran a script which started 2
mpich-processes on each of the x nodes. But with maui, I get x CPUs (every
2nd on the same WN), but not more.
Regards
