[Darshan-users] darshan 3.0.0 official release

[Shane Snyder]

Darshan users,

Darshan 3.0.0, the new modularized implementation of Darshan, is now 
officially ready to be released! This is the first stable release of the 
Darshan 3.0 fork and builds off the experimental pre-releases we have 
been providing over the last few months.  We encourage users to consider 
upgrading to this version in the near future as it contains numerous 
enhancements over older versions: logging of full file paths, clearer 
parser and job summary output, addition of a BG/Q specific 
instrumentation module, future proofing for any upcoming instrumentation 
modules, etc.

The following changes have been made between this official release and 
the last pre-release (darshan-3.0.0-pre3):

* fix bug causing compile errors when building external utilities that 
use the darshan-util API/library
* update docs to give debugging tips for cases where Darshan logs are 
not generated
* update darshan-runtime docs to give information on upgrading Darshan
* fix shared library regression test script to check for potential 
errors with Darshan symbols rather than failing silently in these cases
* bug fix for determining minimum non-zero counters in shared file 
reductions in all modules
* loosen Darshan’s PMPI symbol check to prevent inadvertent disabling of 
Darshan for some MPICH builds
* bug fix for resolving MPI_Gather and MPI_Barrier when LDPRELOADing 
Darshan’s shared libraries
* add more helpful error handling when opening 2.x version log files
* port darshan-diff utility over to new 3.0.0 log file format
* fix numerous configure bugs on Cray systems
* add synthetic benchmarking hooks for testing Darshan’s shutdown procedure

We have tested this version extensively on a number of platforms over 
the last few months and are satisfied with the new features and 
Darshan’s overall performance. Included in the darshan-runtime 
documentation (a link is provided below) is some information on how to 
best upgrade from a Darshan 2.x version to Darshan 3.0.0. As always, 
please let us know if you have any issues or questions (using either the 
Darshan users mailing list or by opening an issue on the Darshan GitLab 
page).
