<p>Dear Darshan Team,</p>
<p>I have installed the latest darshan version (3.3.0) for different
MPIs on our HPC JUWELS
(<a class="moz-txt-link-freetext" href="https://apps.fz-juelich.de/jsc/hps/juwels/configuration.html">https://apps.fz-juelich.de/jsc/hps/juwels/configuration.html</a>) and
would like to report two issues:<br>
</p>
<p>1. Intel (19.1.3.304) Compiler with IntelMPI/2019.8.254:<br>
- Configure Step fails for the new APMPI feature:<br>
<i>cd darshan-runtime; ./configure
--prefix=/path/to/darshan-runtime/3.3.0-iimpi-2020-APMPI
--with-mem-align=8 --with-log-path-by-env=DARSHAN_LOG_P</i><i><br>
</i><i>ATH --with-jobid-env=SLURM_JOBID CC=mpicc
--enable-hdf5-mod=$EBROOTHDF5 --enable-apmpi-mod
--enable-apmpi-coll-sync</i><br>
- Error msg: <i>configure: error: APMPI module requires MPI
version 3+</i><br>
- without the new APMPI Options the configure steps ends
successfully:<br>
<i>cd darshan-runtime; ./configure
--prefix=/p/software/juwels/stages/Devel-2020/software/darshan-runtime/3.3.0-iimpi-2020
--with-mem-align=8 --with-log-path-by-env=DARSHAN_LOG_PATH
--with-jobid-env=SLURM_JOBID CC=mpicc
--enable-hdf5-mod=$EBROOTHDF5<br>
</i><br>
<br>
2. GCC/9.3.0 Compiler with ParaStationMPI/5.4.7-1 (based on MPICH
3.3.2) (<a class="moz-txt-link-freetext" href="https://github.com/ParaStation/psmpi/">https://github.com/ParaStation/psmpi/</a>):<br>
- darshan-runtime configured with <i>--enable-apmpi-mod
--enable-apmpi-coll-sync</i><br>
- For a simple helloworld code (MPI + OMP) the application seems
to be hanging in the MPI_FINALIZE call. <br>
- if I open the *.darshan_partial file with `darshan-parser`, then
the following output is printed:<br>
<i>Error: incompatible darshan file.</i><i><br>
</i><i>Error: expected version 3.21, but got </i><i><br>
</i><i>Error: failed to read darshan log file header.<br>
</i>- There are no issues without APMPI.</p>
<p>3. Further questions:<br>
- Is it possible to switch on/off APMPI during runtime?<br>
- Are there any examples available that demonstrate the additional
value that can be achieved by using the new AutoPerf feature? <br>
- Can you confirm that APMPI works on none-Cray systems ?</p>
<p>Best regards,<br>
Thomas<br>
