I did some testing with this and concluded that the 7240 HCAs performed so much better with PSM that verbs was out of the question (or performed very bad with verbs if one wants to look at it that way). Essentially, they were ok as Qlogic-HCAs but not Infiniband-HCAs (IMHO). Using conservative OpenMPI settings (essentially treating all the HCAs like they were very old/simple) I did get a limited set of simple tests through ok. /Peter
