[mvapich-discuss] MVAPICH-0.9.8 lockup with OFED-1.1-rc3

[Andrew Dobbie]

Yes.  The application I use runs mpirun_rsh and has the same problem as
the benchmarks.  The hostnames I use point to IPoIB addresses of the
machines and all hosts have the same entries in /etc/hosts.  Specifying
which hosts to use on command line or from -hostfile doesn't seem to
matter.

Does that answer the question you were asking?
