Very surprising, given that this works when used from within Hydra. Without running qrsh independently (without Hydra), it's hard to figure out what's going wrong.

Reuti: any ideas on why this is happening?

Below is something I noticed, though that might or might not be a problem.

This doesn't seem to be set on the cluster where mpiexec doesn't work. Is this supposed to be the case?
