[mpich-discuss] Fwd: jobs of mpich2 & mvapich2 on the same cluster?

[Sangamesh B]

Dear MPICH2 team,

        We've a Rocks-5.1 Linux HPC cluster. It has two set of nodes. But
the master node is common for both the sets of nodes. First set is connected
with Infiniband and the second with gigabit.

mpdboot works well for both MVAPICH2 and MPICH2( Version: 1.0.4p1) on the
two sets of nodes respectively, mpds are booted from the same master node.

Also the jobs run well with MVAPICH2 on INFINIBAND.

But the MPICH2 jobs fail with following error:

mpiexec_node28.local (mpiexec 371): no msg recvd from mpd when expecting ack
of request

Is this a bug with MPICH2? Or Is it not possible to run both mpich2 &
mvapich2 mpdboot from the same master node (from the same user)?

Thank you
