Hi All, I have a question similar (but not identical to) the one asked by Tom Fogel a week or so back...
I have a code that uses MPI_Comm_spawn to launch different processes. The executables for these use libraries in non-standard locations, so what I've done is add the directories containing them to my LD_LIBRARY_PATH environment variable, and then calling mpirun with "-x LD_LIBRARY_PATH". This works well for me on OpenMPI 1.6.3 and earlier. However, I've been playing with OpenMPI 1.7.3 and this no longer seems to work. As soon as my code MPI_Comm_spawns, all the spawned processes die complaining that they can't find the correct libraries to start the executable. Has there been a way that exported variables are passed to spawned processes between OpenMPI 1.6 and 1.7? Is there something else I'm doing wrong here? Best Regards, Tim
