Hi Aaron,****
** **
This seams a problem with your MPI library setup with PVFS(2?).****
Maybe Rob will glance over this thread and can tell you what your problem
is.****
** **
The fact where you are saying that your program works with 1 process per
node puzzles me. This rules out the problem where the file is not visible
from other nodes.****
So I am not really sure what the problem here is.****
** **
Thanks,****
Mohamad****

Mohamad,****

Thanks for your help. ****

When I ran Simple_mpio.c with 2 nodes and 2 ppn, I again got segmentation
faults. It works fine when the processes are all on separate nodes. It
also works when all processes are on the same node.****
** **
What could cause this? What do I need to tell the system administrator
needs to be fixed?****
** **
I haven't been able to figure out a version number for myricom yet.****

How would I find the MPICH version for myricom? If there is a way to
query the system, I'll do that tomorrow when I re-run the mpio test (I've
run it before, but I don't know that I tried different ppn vs. node
distributions).****
****
[msc] maybe mpicc –version :-?****
****
Also for the configure and make output, can I simply send those as an
attachment with a reply email?****
****
[msc] Sure. ****
