[Darshan-users] Darshan 2.3.1-pre2 release

[Phil Carns]

Darshan 2.3.1-pre2 is now available on the download 
<http://press3.mcs.anl.gov/darshan/download/> page for testing and 
feedback.  The most significant changes since 2.3.1-pre1 are better 
support for recent MPICH releases, examples and documentation for the 
-profile hooks in MPICH, and the addition of a regression testing 
framework.  Our plan is to feature freeze at this point and focus on 
platform testing for the final 2.3.1 release.

The full changelog since 2.3.0 is as follows:

darshan-2.3.1-pre2
=============
* added documentation and example configuration files for using the -profile
   or $MPICC_PROFILE hooks to add instrumentation to MPICH-based MPI
   implementations without generating custom wrapper scripts
* Add wrappers for mkstemp(), mkostemp(), mkstemps(), and mkostemps()
   (reported by Tom Peterka)
* Change OPEN_TIMESTAMP field to report timestamp right before open() is
   invoked rather than after timestamp after open is completed.
   NOTE: updated log format version to 2.06 to reflect this change.
* Change start_time and end_time fields in job record to use min and max
   (respectively) across all ranks
* Fix bug in write volume data reported in file system table in
   darshan-job-summary.pl (reported by Matthieu Dorier)
* Clean up autoconf test for zlib and make zlib mandatory (reported by 
Kalyana
   Chadalavada)
* add --start-group and --end-group notation to Darshan libraries for 
Cray PE
   2.x environment to fix link-time corner cases (Yushu Yao)
* improve y axis labels on time interval graphs in darshan-job-summary.pl
   (reported by Tom Peterka)
* misc. improvements to darshan-parser --perf output (reported by Shane
   Snyder)
   - indicate which rank was slowest in unique file results
   - label I/O vs. meta time more clearly
   - include unique file meta time in agg_perf_by_slowest calculation
* added regression test script framework in darshan-test/regression/
   - workstation-static and workstation-dynamic test environments supported
* update darshan-gen-fortran.pl and darshan-gen-cxx.pl to support new 
library
   naming conventions in MPICH 3.1.1 and higher
* update documentation to reflect known issues with some versions of MPICH

thanks,
