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