I've just tried 1.5.3 under SGE with tight integration, which seems to be broken. I built and ran in the same way as for 1.4.{1,3}, which works, and ompi_info reports the same gridengine parameters for 1.5 as for 1.4.
The symptoms are that it reports a failure to communicate using ssh, whereas it should be using the SGE builtin method via qrsh. There doesn't seem to be a relevant bug report, but before I investigate, has anyone else succeeded/failed with it, or have any hints?
