Gilbert, as you have an SGI cluster, have you filed a support request to SGI? Also, which firmware do you have installed? I have Firmware version: 2.5.0 http://www.openfabrics.org/downloads/OFED/ofed-1.4/OFED-1.4-docs/mlx4_release_notes.txt Features that are enabled with FW 2.5.0 only: - Send with invalidate and Local invalidate send queue work requests. - Resize CQ support.
