[Darshan-users] Darshan 3.4.7 release is now available

[Snyder, Shane]

Darshan users,
Darshan version 3.4.7 is now officially available for download HERE<https://www.mcs.anl.gov/research/projects/darshan/download/ >. This point release most notably includes new modules enabling detailed instrumentation of DAOS storage systems (e.g., on ALCF Aurora):

  *   There are 2 new modules that instrument the DAOS file system interface (DFS) and native object interfaces (DAOS).
  *   Darshan’s heatmap module also now supports capture of I/O activity across both of these new DAOS modules.

We have also released PyDarshan 3.4.7.0 on PyPI, which includes the following new capabilities:

  *   New PyDarshan CLI tools for extracting statistics from one or more input log files:
     *   job_stats: Overall job-level I/O statistics for each input Darshan log
     *
file_stats: Overall file-level I/O statistics for application files accessed across each input Darshan log
     *
Each tool offers command line options to control how jobs/files are sorted, statistics output format (CSV or Rich-style printing), Darshan module to analyze, etc.
  *   Support for reading DAOS module data, as well as integrations of DAOS data into PyDarshan summary reports.
  *   Support for PyDarshan ReportObject name filtering, enabling users to provide record name patterns to match when reading data from Darshan logs.
     *   Available via filter_patterns and filter_mode arguments to various ReportObject routines:
        *   filter_patterns: list of regexes to match
        *   filter_mode: “exclude” or “include” records matching provided regexes
