<br>
You might need to use the --export option to srun to make sure
that the LD_PRELOAD environment variable is propagated to the
executable at run time. <br>

<br>
I'm not an expert on slurm, but I suspect that it isn't
propagating all of your environment variables by default.<br>
<br>
Also, is this by any chance a system where executables compiled
for the compute nodes will run correctly on the login node as
well? If so, then you might want to start by debugging a local
invocation of mpi-io-test by just running it without mpiexec or
slurm (i.e., "./mpi-io-test") to narrow down the problem. You
might also be able to do that in an interactive job on the compute
nodes.<br>

<div>Hi,</div>
<div>I'm having trouble when trying to run Darshan with Fortran.
I tried to dynamic link Darshan with mpich3.1.3(intel compiler
version 15.0.1) applications following the instructions here.
But there is no log file generated, and no error. Could you
give me any suggestion on how to fix it?</div>

<div><a class="moz-txt-link-rfc2396E" href="http://www.mcs.anl.gov/research/projects/darshan/docs/darshan-runtime.html"><http://www.mcs.anl.gov/research/projects/darshan/docs/darshan-runtime.html></a></div>
<div><br>
</div>
<div>Here is my steps:</div>
<div>1. Compile and install darshan 3.1.4</div>
<div>tar -xvzf darshan-3.1.4.tar.gz</div>
<div>cd darshan-3.1.4/darshan-runtime</div>
<div>./configure --with-mem-align=8 --with-log-path=<log
directory> --with-jobid-</div>
<div><br>
</div>
<div>env=SLURM_JOB_ID CC=mpicc --prefix=<install
directory> --with-zlib=<zlib </div>
<div><br>
</div>
<div>directory> --enable-HDF5-pre-1.10
--enable-group-readable-logs </div>
<div>make</div>
<div>make install</div>
<div>./prepare </div>
<div><br>
</div>
<div>2. Create log directory, which successfully create the
directory</div>
<div>perl darshan-mk-log-dirs.pl</div>
<div><br>
</div>
<div>3. Set up the environment</div>
<div>export PATH=/<darshan-3.1.4 install
directory>/bin:$PATH</div>
<div>export LD_LIBRARY_PATH=/<darshan-3.1.4 install
directory>/lib:$LD_LIBRARY_PATH</div>
<div>export INCLUDE=/<darshan-3.1.4 install
directory>/include:$INCLUDE</div>
<div>export CPATH=/<darshan-3.1.4 install
directory>/include:$CPATH</div>
<div>export
LD_PRELOAD=/path/to/mpi/used/by/executable/lib/libfmpich.so:/<darshan-3.1.4
install directory>/lib/libdarshan.so</div>
<div><br>
</div>
<div>4. Compile application (mpi-io-test.f90)</div>
<div>mpif90 mpi-io-test.f90 -o mpi-io-test</div>
<div><br>
</div>
<div>5. Run application</div>
<div>srun -n 24 -p partitionname application</div>
<div><br>
</div>
<div>When the application runs complete, no logs is generated. I
don't know what the problem is. Can you help me?</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Zhong</div>
</div>
