When they are installed in the location where "--prefix=..." pointed to during `./configure` it will work. If you moved them afterwards to different locations, it might be necessary to point OPAL_PREFIX to the destination you moved it to before you call `mpiexec`. But you will have to have different compiled versions of your applications too. Between 1.6 and 1.7 the ABI may have changed, only the combination odd + next even major release of Open MPI is guaranteed to have the same ABI. -- Reuti > Grepping through the Open MPI installations for torque used during > installation gave me some hits in binaries like mpirun or the static libs. > I would appreciate any hints. > > Best regards > Christoph Niethammer > _______________________________________________ > users mailing list > us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/users
