Darshan version 3.1.0 is now available for release! This version
contains a number of general enhancements to the code base:<br>
<br>
* addition of a stdio I/O library instrumentation module<br>
- this handles more in-depth instrumentation of file stream I/O
functions like fopen(), fprintf(), fscanf(), etc.<br>
- this module also captures stats on the standard I/O streams
(stdin, stdout, & stderr)<br>
* addition of a Lustre instrumentation module<br>
- this module provides Lustre striping details (e.g., stripe
width, stripe size, list of OSTs a file is striped over) for files
stored on Lustre file systems<br>
* addition of a new mmap-based logging mechanism that allows Darshan
to generate output logs even in cases where applications don’t call
MPI_Finalize()<br>
- note that these logs are uncompressed and are per-process
rather than per-job<br>
* addition of the darshan-merge utility to darshan-util to allow
per-process logs generated by the mmap-based logging mechanism to be
converted into Darshan’s traditional compressed per-job log files<br>
* modification of the POSIX module timestamp counters to also
include a LAST_OPEN & FIRST_CLOSE counters to give more details
on application I/O intervals<br>
<br>
This version has been tested extensively on a number of platforms.
