We currently build 4 versions of Open-MPI for the various Fortran compilers: gfortran, Intel, Pathscale and PGI.We modify the build so that the compiler name is part of the rpm filename. For the final install of the package we end up with the following:/opt/OpenMPI/openmpi-<version>-<compiler>/Users software environments are controlled via the Module package, thus a user will load her favorite flavor of compiler and Open-MPI module at login or some other time and LD_LIBRARY_PATH and PATH, etc, are set accordingly.

We would like to do thisvia rpms so we can easily push any changes out to the compute nodesand try to eliminate any versioning problems. I was thinking a different rpm nameand different locations and then users would have to adjust environmentvariables to use a particular build.Is this how other sites have handled this?Any suggestions or hists around this issue would be most appreciated.--Steve_______________________________________________users mailing list_______________________________________________users mailing list
