[gridengine users] Tight integration problem with mvapich2 2.0

Hi everyone,

I have noticed one difference in the behaviour of mvapich2 between 1.8 and
2.0rc1: with the former, hydra_pmi_proxy and all mpi processes are in the
same process group, but with the later version, they all have a different
pgid. Just killing hydra_pmi_proxy will terminate all mpi processes with
1.8 but not with 2.0rc1.

Any idea to work around this?

Regards, Götz
