Thanks for your post ... Hope your problems are short-lived :-)

viacheck.c is an internal file in the MVAPICH implementation. I have a
couple of questions which you could answer ...

1) How many nodes was this run attempted? I have run osu_bcast on
64-nodes/128 processes and it seems to be OK.

2) Can you run IMB (Intel MPI benchmarks)? They will also call
MPI_Bcast.

3) I'm wondering if you could run the other OSU benchmarks, such as
latency, bandwidth, bi-directional bandwidth?

Thanks,
Sayantan.
