[Bug report] Darshan and Fortran (mpif90)
by 8schroed＠informatik.uni-hamburg.de 21 Jul '11

21 Jul '11

Hello, I tried to run Darshan with Fortran. For testing I wrote a short program which is using MPICH2 and MPI-I/O (see the attachment hello-world-mpi.f90). After compiling the code with Darshan and running the executable, Darshan didn't generate a logfile. To find the cause I analysed the Mapfile "$tmpfile" which is created with the build. The main interesting part in this file shows the symbols of MPI-functions: 0x0000000000400b58 mpi_comm_rank_ 0x0000000000400b68 mpi_file_close_ 0x0000000000400b78 mpi_file_open_ .... 0x0000000000400bd8 mpi_file_write_ 0x0000000000400be8 mpi_init_ 0x0000000000400bf8 mpi_finalize_ 0x0000000000400c08 mpi_comm_size_ But in mpif90 (of Darshan) the "grep"-command in line 84 is searching for "MPI" in upper case even though "MPI" is written in lower case in the Mapfile: grep MPI $tmpfile As a result the script "mpif90" of MPICH2 is executed instead of Darshan, because "grep" sent an exitcode equal 1. By adding the "-i" option, "grep" ignores case distinctions and the exit code is equal 0. Now mpif90 of Darshan will be used and after running the program there is a logfile in the log directory. Please take note of this bug and fix it in your Darshan-mpif90 to avoid the problem of case sensitivity. Best regards, Sandra

darshan output from log

Hello, Now, I have been able to use Darshan as far as generating the Darshan log from the binary execution. However, when I try to generate the output.pdf report as shown in darshan wiki: ~/darshan-install/bin/darshan-job-summary.pl ketan_modftdock_id9643_5-24-42129-16735182948803816265_1.darshan.gz --output ~/job-summary.pdf I get the following: cp: cannot stat `/home/ketan/darshan-install/share/*.gplt': No such file or directory cp: cannot stat `/home/ketan/darshan-install/share/*.tex': No such file or directory Slowest unique file time: 0 Slowest shared file time: 0.058647 Total bytes read and written by app (may be incorrect): 243 Total absolute I/O time: 0.058647 Cannot open load file 'counts-eps.gplt' line 0: util.c: No such file or directory EPSTOPDF 2.9.3draft, 2003/04/20 - Copyright 1998-2002 by Sebastian Rahtz et al. !!!

Darshan installation question
by ketan 23 May '11

23 May '11

Hello, I am new to Darshan. Trying to install on ci login node with the following commandline from the INSTALL file: ./configure --with-mem-align=64 --with-log-path=$LOGPATH --prefix=$PREFIX However, I get the following: configure: error: must provide --with-mpi=<path> argument to configure if mpicc is not in path. The install file does not seem to mention mpi is mandatory. Is it possible to avoid the above flag while installation as our requirement does not include mpi. Thanks, Ketan
