Darshan-users,
Darshan version 3.4.6 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 enhancements to Darshan's Lustre instrumentation module to capture more extensive details on Lustre striping configurations
*
Lustre file records now composed of potentially multiple component counter sets (e.g., LUSTRE_COMP1_*, LUSTRE_COMP2_*, etc.)
*
Allows full characterization of newer Lustre striping features, including progressive file layouts , data-on-metadata, file-level redundancy, and self-extending layouts
*
Fixed bugs in Darshan's log compression/decompression routines that are triggered when using the zlib-ng software package, a new implementation of the zlib compression library
*
darshan-runtime bug fix corrects problematic log compression strategy
*
darshan-util bug fix corrects logs already generated with this issue
*
Fixed bug leading to hangs when parsing improperly formatted Darshan runtime library configuration settings
We have also released PyDarshan 3.4.6.0 on PyPI, though this is just to track the 3.4.6 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… >.
Please report any questions, issues, or concerns with this release on our Slack instance, using this mailing list, or by opening an issue on our GitHub.
Thanks!
