I would consider HDF to be pretty silly library if this were expected behavior. :) Clearly there is something wrong with how I have it set up or how the cluster is reacting to it. I just have no idea what it could be.
We use MPICH-MX <http://www.myricom.com/support/downloads/mx/mpich-mx.html>. I compile using GNU 3.4.3. The system uses PVFS. My compile is fairly simple: #!/bin/tcsh make clean #must make sure mpicc is in the path first setenv CC "mpicc" ./configure --prefix=[installDir] |tee hdf5cfg.log make |tee make.log make install prefix=[installDir] |tee make_install.log Again, any help or advice on fixing this is greatly appreciated.
