Description

The HDF5 library is available for AMPI at
https://charm.cs.illinois.edu/gerrit/#/admin/projects/hdf5-ampi

This bug tracks several of the issues that are still needed for complete support.

History

#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)
  • Migration
  • Some spurious crashes/segfaults at hdf5 library termination
  • Test other architectures than linux/netlrts. Currently works with:
    - netlrts-linux-x86_64
    - netlrts-linux-x86_64 smp
    - multicore-linux-x86_64

#2 Updated by Sam White 7 days ago

'-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.
