Also, my openib.conf is Thats the giveaway ... This uses the Centos 5.5 IB support. I don't know if the drivers in it were updated for your card. That ib_uverbs is loaded, but it doesn't support verbs suggests that the driver may not be fully functional. The IB in Centos 5.x is somewhere between 1.3 and 1.4 OFED. If you can get the openfabrics stack on there, say 1.5.1, you should be fine (1.5.2 has released, but we haven't played much with it yet, apart from some Qlogic cards, which didn't like it much). -- Joseph Landman, Ph.D Founder and CEO Scalable Informatics, Inc. email: landman at scalableinformatics.com web : http://scalableinformatics.com http://scalableinformatics.com/jackrabbit phone: +1 734 786 8423 x121 fax : +1 866 888 3112 cell : +1 734 612 4615
