m_mem_free is part of Univa SGE (but not the various free ones of SGE AFAIK). Also: this syntax is for SGE, in LSF it's different. To have this independent from the actual queuing system, one could look into DRMAA V.2 (unfortunately not many are supporting this version of DRMAA). -- Reuti _______________________________________________ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users
