Description

NOvA would like a product stack that includes hep_hpc. The version of hdf5 needs to match the version used by caffe.

Per Chris Green, we need hep_hpc v0_08_07. We probably also want to include the hep_hpc_toolkit bundle so that h5py is available.

Also, check and make sure this bundle includes the latest castxml.

#3 Updated by Lynn Garren over 1 year ago

caffe v1_0k has been made available. It is built with hdf5 v1_10_2a, protobuf v3_5_2, and lapack v3_8_0a.

#4 Updated by Lynn Garren over 1 year ago

Issues with NOvA code being unable to activate compression on HDF5 output datasets were identified, and Brandon has implemented the correct scheme in his code. Steven will propagate those changes to the modern code generation system within NOvA.

It was also noticed that NOvA is not activating the recommended HDF5 error handling mode. This should be done once per job:
    #include "hep_hpc/hdf5/errorHandling.hpp" 
    ...
      ErrorController::setErrorHandler(ErrorMode::EXCEPTION);

Errors were identified in hep_hpc which had contributed to the difficulty of tracing the issue:
  • Faulty logic in an assertion in hep_hpc::hdf5::setColumnProperties(), called by make_column().
  • Logic in hep_hpc::hdf5::PropertyList::isClass(), which returned true if the underlying call to H5Pequal() failed and the recommended error handling setting (see above) was not in place. It now returns false in this case.

Armor was applied to hep_hpc/Utilities/detail/compiler_macros.hpp to mitigate compiler notes in compilation units which also include (usually indirectly) cetlib/compiler_macros.h. Similar armor has been applied to cetlib, but as a workaround one should ensure that hep_hpc headers are included after any art framework headers.

There are new versions of hep_hpc (v0_08_09) and hep_hpc_toolkit (v00_08_09). There have been no changes to other dependencies.

hep_hpc_toolkit v00_08_09 is now available on SciSoft
