There is a pre-release available for download today for a new
experimental version of Darshan! You can download it here: <a
class="moz-txt-link-freetext"
href="ftp://ftp.mcs.anl.gov/pub/darshan/releases/darshan-3.0.0-pre1.tar.gz">ftp://ftp.mcs.anl.gov/pub/darshan/releases/darshan-3.0.0-pre1.tar.gz</a>.<br>
<br>
Darshan 3.0.0 provides much of the same functionality of prior
versions, but with the following new enhancements and features:<br>
* hooks for developers to add their own instrumentation module<br>
implementations to capture new I/O characterization data<br>
- these instrumentation modules can be used to instrument
new<br>
I/O interfaces or gather system-specific parameters, for
instance<br>
* modularized log format allows new module-specific utilities to<br>
access their I/O characterization data independently<br>
- this new format also allows new counters to be added to
existing<br>
instrumentation modules without breaking existing
utilities<br>
* Darshan logs now contain a mapping of Darshan's unique record<br>
identifiers to full file names, instead of fix-sized file name<br>
suffixes<br>
* a new instrumentation module for capturing BG/Q-specific
parameters<br>
(BG/Q environment is automatically detected at configure time)<br>
* new darshan-parser and darshan-job-summary output to utilize
the<br>
new modularized log format<br>
<br>
This version is *not* intended for use in a production environment,
yet, so please just use for testing for now. We have had success in
the cross-platform testing we have done so far, but more thorough
testing is necessary before we are ready for to officially release
the new modularized implementation. Issues can be reported directly
to the mailing list or using the new issue tracking feature at the
Darshan GitLab page (<a class="moz-txt-link-freetext"

As always, we welcome any feedback you may have!<br>
