Known Problems: Example Programs

This page includes example programs to help diagnose known problems.

Problem Reading A Collectively Written Dataset In Parallel

Following are examples that reproduce a problem of reading a dataset in parallel shortly after it has been written to collectively. (The problem appears to be due to certain MPI implementations and/or filesystems.) A detailed description of the problem can be found on the HDF5 Known Problems page.

Pure MPI Example: tmpi.c
Standalone HDF5 Example: t_mpi_bug_hdf5.c
