I am finding, on linux, rhel7, with openmpi 1.8.8 and 1.10.3, that mpirun won't find apps that are specified on a relative path, i.e, if I have
PATH=dir/bin and I am in a directory which has dir/bin as a subdirectory, and an executable bir/bin/myprogram, I can't do mpirun myprogram I get the error message that mpirun was unable to find the specified executable file, and therefore did not launch the job. whereas if I put an absolute path, something like PATH=/home/me/dir/bin then it works. This causes some problematic silent failure, sometimes we use relative directories to override a 'base' release, so if I had PATH=dir/bin:/central/install/dir/bin and myprogram was in both dir/bin and /central/install/dir/bin, through mpirun, I would be running myprogram from the central install, but otherwise I would run it from my own directory. Do other people find this is the case? I wonder if it is a problem that got introduced through our installation of openmpi. We do create relocatable rpm's, and I'm also trying openmpi from a conda package that is relocatable, I think all the prefix paths in the binary and text files were corrected properly for the install - at least everything else seems to work. best, David Schneider SLAC/LCLS _______________________________________________ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users
