Dear all!
I encountered an issue with creating a hdf5 file parallely. On my local machine it works fine, but on the computation cluster it does not.
If I compile and run the simple example "Hyperslap_by_row.c" of the TUTOR page, I wont get past
file_id = H5Fcreate(H5FILE_NAME, H5F_ACC_TRUNC, H5P_DEFAULT, plist_id);
if I run it with more than one process. The function seems to be blocking, the file however is created with zero size.
I compiled hdf5-1.8.8 (tried 1.8.7 too) with mpicc of the HP implementation (hp-mpi-2.3.1) and tried both gnu and intel compilers.
Are there known issues with hp-mpi?
Any ideas? Any suggestions on how to better debug this problem?

Hi Tobias,
Dear all!

Is the file located on a file system accessible by all the nodes on your cluster?

Not that I know of. However, we do not test with hp-mpi. We test with mpich2, which uses ROMIO as the MPI-I/O implementation.
Any ideas? Any suggestions on how to better debug this problem?
How did you configure HDF5? Can you build it with debug enabled, and trace the calls internally in HDF5 to pin point where the problem is? I do not have access to any machine with hp-mpi to try it.
Thanks,
Mohamad
