The official release for Darshan version 3.1.3 is now available for
download <a
href="ftp://ftp.mcs.anl.gov/pub/darshan/releases/darshan-3.1.3.tar.gz">here</a>.
We have tested this release extensively and believe it is stable and
ready for use in production. On top of the numerous new features and
bug fixes included in the darshan-3.1.3-pre1 release (listed in the
original email copied below), the official version has one
additional bug fix:<br>
<br>
* Instrumentation of mmap calls is now disabled for dynamically
linked applications (i.e., applications that LD_PRELOAD darshan)<br>
- this avoids potential deadlock issues on Cray systems when
using dynamically linked executables (reported by Cristian Simarro)<br>
<br>
You can find updated documentation for darshan-runtime and
darshan-util components <a
href="http://www.mcs.anl.gov/research/projects/darshan/documentation/">here</a>.
<br>
<br>

Darshan users,<br>
<br>
A new Darshan pre-release (3.1.3-pre1) is now available for
download <a moz-do-not-send="true"
href="ftp://ftp.mcs.anl.gov/pub/darshan/releases/darshan-3.1.3-pre1.tar.gz">here</a>.
Please be aware that this pre-release is experimental and *not*
recommended for full-time use in production yet. We hope to have
the official 3.1.3 release ready some time next week.<br>
<br>
Here is the list of new features and bug fixes in this release:<br>
<br>
* New DxT (Darshan eXtended Tracing) instrumentation modules that
provide fine-grained tracing data of read/write operations at the
POSIX & MPI-IO layers<br>
- This tracing module is not enabled by default, and it is
envisioned that it be enabled selectively at runtime for
applications of interest<br>
- This code was contributed by Cong Xu and Intel's High
Performance Data Division (HPDD)<br>
* Darshan now captures command line arguments for Fortran
applications<br>
- This fix was contributed by Cristian Simarro<br>
* Fix potential deadlock when using the Cray hugepages module and
Darshan<br>
- Reported by Glenn Lockwood & Cristian Simarro<br>
* Fix potential segmentation fault when Darshan exceeds the
maximum number of tracked access sizes/strides<br>
- Reported by Glenn Lockwood<br>
* Disable Darshan's HDF5 module by default to avoid potential ABI
compatibility issues with HDF5<br>
- New configure switches are provided to enable Darshan
support for specific HDF5 library versions<br>
- Problem report and initial patch provided by Karl-Ulrich
Bamberg<br>
* Add whitelist to Darshan's list of file path exclusions to
prevent I/O to/from Cray's Datawarp service from being filtered
out<br>
- Contributed by Glenn Lockwood<br>
<br>
Updated documentation related to using the DxT tracing modules can
be found in the source tree ('darshan-runtime/docs' for the
Darshan runtime library & darshan-util/docs for Darshan's
utilities). To summarize, DxT tracing can be enabled at runtime by
exporting the 'DXT_ENABLE_IO_TRACE' environment variable. DxT also
has a corresponding parser utility named 'darshan-dxt-parser' that
can be used to parse trace data out of Darshan log files.<br>
<br>
As always, let us know if you have any questions, issues, or
concerns using this mailing list, or by opening an issue on the <a
