Darshan users,
Darshan version 3.4.5 is now officially available for download here: https://urldefense.us/v3/__https://www.mcs.anl.gov/research/projects/darsha… . This point release includes a couple of important new capabilities and bug fixes:
*
Added capability for Darshan's runtime library to properly shutdown in non-MPI applications that call _exit() directly
*
This behavior has been commonly observed in the Python multiprocessing package, which has traditionally prevented Darshan from properly instrumenting applications that use it (e.g., the PyTorch DataLoader)
*
Added optional integration with the LDMS data/metrics collection system, allowing realtime analysis of Darshan instrumented I/O operations
*
For more details, see https://urldefense.us/v3/__https://ovis-hpc.readthedocs.io/en/latest/ldms/l…
*
Contributed by Sara Walton and the LDMS team
*
Fixed bug preventing instrumentation of fscanf() calls on some systems
*
Fixed bug in HDF5 module causing any call to HDF5's H5Pset_fapl_mpio() routine to fail
We have also released PyDarshan 3.4.5.0 on PyPI, though this is just to track the 3.4.5 darshan-util library. There are no modifications to PyDarshan functionality.
Documentation for Darshan and PyDarshan is available here: https://urldefense.us/v3/__https://www.mcs.anl.gov/research/projects/darsha… .
