I'm leaning towards fixing it - it came due to discussions on how to handle hostfile when there is an allocation.

Can you run 1.6.1 with the following on the mpirun cmd line: -mca ras_gridengine_debug 1 -mca ras_gridengine_verbose 10 -mca ras_base_verbose 10 My guess is that something in the pe_hostfile syntax may have changed and we didn't pick up on it. > -- Reuti > > >> >>> >>> == >>> >>> I configured with: >>> >>> ./configure --prefix=$HOME/local/... --enable-static --disable-shared >>> --with-sge >>> >>> and adjusted my PATHs accordingly (at least: I hope so). >>> >>> -- Reuti >>> _______________________________________________ >>> users mailing list >>> us...@open-mpi.org >>> http://www.open-mpi.org/mailman/listinfo.cgi/users >> >> >> _______________________________________________ >> users mailing list >> us...@open-mpi.org >> http://www.open-mpi.org/mailman/listinfo.cgi/users > > > _______________________________________________ > users mailing list > us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/users
