[Darshan-users] darshan-3.4.5 is now available

[Snyder, Shane]

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/darshan/download/__;!!G_uCfscf7eWS!e-k9hSpr5CKhQrCXpSHTk_aLnyfIsRQvJxAImXfFMXOQMY8bOnwGrAo4gSK7CFcqJMqfBRBR8RoECRsCmK_q0OL-l7rtxvw$ . 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/ldms-streams.html*darshan__;Iw!!G_uCfscf7eWS!e-k9hSpr5CKhQrCXpSHTk_aLnyfIsRQvJxAImXfFMXOQMY8bOnwGrAo4gSK7CFcqJMqfBRBR8RoECRsCmK_q0OL-nmp9lCg$ 
     *
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/darshan/documentation/__;!!G_uCfscf7eWS!e-k9hSpr5CKhQrCXpSHTk_aLnyfIsRQvJxAImXfFMXOQMY8bOnwGrAo4gSK7CFcqJMqfBRBR8RoECRsCmK_q0OL-XGfL6dY$ .
