HDF5 issues in AMPI
The HDF5 library is available for AMPI at
This bug tracks several of the issues that are still needed for complete support.
#1 Updated by Matthias Diener 9 days ago
The issues to test and improve are:
- Test if applications work with the shared library (currently, only the static hdf5 library is built)
- This is currently blocked by the lack of a shared-library ROMIO
SMP mode(seems to work 07/16) Virtualization(seems to work 07/16)
- Some spurious crashes/segfaults at hdf5 library termination
- Test other architectures than linux/netlrts. Currently works with:
- netlrts-linux-x86_64 smp
'-tlsglobals' currently requires static linking: https://charm.cs.illinois.edu/redmine/issues/1220
For migration, the main concern is migrating with open files: so far we've told users to explicitly close and re-open files before and after migration (or if doing serial I/O, make that rank non-migratable), but we could potentially do that for them in our ROMIO and HDF5 distributions.
