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 From: Hdf-forum [mailto:[email protected]] On Behalf Of Aaron Friesz Sent: Saturday, October 19, 2013 5:12 PM To: HDF Users Discussion List Subject: Re: [Hdf-forum] H5Fcreate when using multiple nodes and multiple processors per node 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.

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.
