Darshan 2.2.0 release

March 13th, 2012

Darshan 2.2.0 is now available for download.   The biggest change is that this release splits the code into separate components for instrumentation and analysis.  There are also several improvements in documentation, portability, and an assortment of bug fixes.

Changelog:

  • split darshan into separate packages:
    • darshan-runtime: for runtime instrumentation
    • darshan-utils: for processing darshan log files
  • changed default output file name for darshan-job-summary.pl to be based on input file name rather than summary.pdf
  • reorganized init and finalize routines so that can be linked separately (to allow for easier integration with other instrumentation tools)
  • add -cc, -cxx, -f77, -f90, and -fc support to compiler scripts generated by the darshan-gen-*.pl scripts
  • bug fixes:
    • potential MAX_BYTE overflow on 32 bit systems
    • incorrect pread and pwrite offset tracking
    • corrections to darshan-job-summary variance table
    • better runtime error handling if bzip or gnuplot tools are insufficient
    • improvements to time range in darshan-job-summary graphs
  • documentation:
    • improved documentation for both the darshan-runtime and darshan-util portions of Darshan can be found in the respective doc/ subdirectory for each
