But I would be interested in a statement about a hostlist for singleton startups. Or whether it's honoring the tight integration nodes more by accident than by design. And as said: I see a wrong allocation, as the initial ./Mpitest doesn't count as process. I get a 3+1 allocation instead of 2+2 (what is granted by SGE). If started with "mpiexec -np 1 ./Mpitest" all is fine.
