IIRC, the rationale behind adding the check was that someone using SGE wanted to specify a custom launch agent, and we were overriding it with qrsh. However, the check is incorrect as that MCA param cannot be NULL.
I have updated this on master - can you see if this fixes the problem for you? https://github.com/open-mpi/ompi/pull/1957 As for the blank in the cmd line - that is likely due to a space reserved for some entry that you aren’t using (e.g., when someone manually specifies the prefix). It shouldn’t cause any harm as the cmd line parser is required to ignore spaces The -ldl problem sounds like a configuration issue - you might want to file a separate issue about it > On Aug 11, 2016, at 4:28 AM, Reuti <re...@staff.uni-marburg.de> wrote: > > Hi, > > In the file orte/mca/plm/rsh/plm_rsh_component I see an if-statement, which > seems to prevent the tight integration with SGE to start: > > if (NULL == mca_plm_rsh_component.agent) { > > Why is it there (it wasn't in 1.10.3)? > > If I just remove it I get: > > [node17:25001] [[27678,0],0] plm:rsh: final template argv: > qrsh <template> orted --hnp-topo-sig ... > > instead of the former: > > /usr/sge/bin/lx24-amd64/qrsh -inherit -nostdin -V -verbose <template> orted > --hnp-topo-sig ... > > So, just removing the if-statement is not a perfect cure as the > $SGE_ROOT/$ARC does not prefix `qrsh`. > > == > > BTW: why is there blank before " orted" in the assembled command line - and > it's really in the argument when I check this on the slave nodes what should > be started by the `qrsh_starter`?
