I seem to recall that you have an IB-based cluster, right? >From a *very quick* glance at the code, it looks like this might be a simple >incorrect-finalization issue. That is:
- you run the job on a single server - openib disqualifies itself because you're running on a single server - openib then goes to finalize/close itself - but openib didn't fully initialize itself (because it disqualified itself early in the initialization process), and something in the finalization process didn't take that into account Nathan -- is that anywhere close to correct?
