[Darshan-users] Darshan 2.0.0 release

[Phil Carns]

The Darshan 2.0.0 release is now available for download.  From a user's 
perspective, the biggest difference is that you no longer have to run 
darshan-parser before darshan-job-summary.pl if you just want to see the 
summary report for a job.  The darshan-job-summary.pl script operates 
directly on the binary .gz files now.  We also introduced new 
characterization counters as well as some additional tables in the 
summary view.  Here is the full change log:

darshan-2.0.0
=============
* new output file format that is portable across architectures
   NOTE: Darshan 1.x output files are incompatible with the tools in this
   release unless they were generated on a ppc32 architecture (Blue Gene)
* 8 new counters that record the rank of the fastest and slowest process 
that
   opened each shared file, along with the number of seconds and number of
   bytes consumed by those processes.  It also reports the variance in both
   time and amount of data.
* new --with-jobid-env configure argument to support recording job 
identifiers
   from different schedulers
* job ID is now recorded within the Darshan log in addition to in the file
   name
* darshan-job-summary.pl:
   * opens output files directly without using intermediate 
darshan-parser output
   * table showing data usage per file system
   * table showing I/O variance in shared files
* Fixes for bugs reported by Noah Watkins:
   * avoid name collision in hashing function
   * divide by zero error in darshan-job-summary.pl
