Hi, I have recently started working with Darshan 2.3.1 on my system. I have installed all the prerequisites: Perl, pdflatex, epstopdf, and gnuplot to enable darshan-job-summary.pl utility. I have few questions specified below regarding the use of darshan-summary-per-file.sh and darshan-job-summary.pl. System specification: Kernel Version: Linux 4.0.5-1.el7.elrepo.x86_64 Operating System: CentOS Linux release 7.1.1503 CPU: Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz (Haswell-EP) Architecture:x86_64 Compiler: GCC 5.1.0 MPI: Intel MPI #### BEGIN : output of darshan-summary-per-file.sh $ darshan-summary-per-file.sh carns_mpi-io-test-ppc64-2.3.1_id426989_3-13-61875-4723177368895607730_1.darshan.gz ../output Status: Generating summary for file 1 of 1: mpi-io-test.dat ======================================================= Slowest unique file time: 0 Slowest shared file time: 0.190554 Total bytes read and written by app (may be incorrect): 33554432 Total absolute I/O time: 0.190554 LaTeX generation (phase1) failed [256], aborting summary creation. error log: or enter new name. (Default extension: sty) Enter file name: ! Emergency stop. <read *> l.8 \usepackage {multirow}^^M ! ==> Fatal error occurred, no output PDF file produced! Transcript written on summary.log. ======================================================= darshan-summary-per-file.sh done. Results can be found in /nfs/fx/proj/coralhpctools/users/psuman/myBuilds/Darshan/gcc/0904_logs/out1/*.pdf. #### END: darshan-summary-per-file.sh I am using the few benchmarks and darshan-test/example-output files to test the installation. There is no PDF file generation while running the darshan-summary-per-file.sh or darshan-job-summary.pl utility. Here are few questions: a) Is the error message of darshan-summary-per-file.sh utility mentioned above linked to Darshan or PDFLatex? b) Is there any other dependency needed to enable darshan-summary-per-file.sh and other utilities? c) If this is not a dependency error, What could be the reason for the error? Will greatly appreciate your response. Thanks, Preeti
