[Darius Buntinas]

Oops, sorry I thought you said there was a seg fault.  Never mind getting a core dump.  What is the error message you're getting?

-d

What is different is that in this version of the app we are sending materially larger and more volume of data back to Node 0.  We develop and test in Windows 7 and we are suing smpd there, and things are bullet proof.  In the past problem were easily recreated, so this is really puzzling.  We are building with gcc and have not had any problems in the past in terms of MPI when we transition between RH and Window so the implications of this are dismaying.

If we run smpd in RH Linux there is no problem.  I suspect this has probably been seen before but I have had no luck in a Google search so my apologies if this has been answered before.  But could someone be so kind as to tell me what we have done to ourselves if this is a known problem.
