MOFED 2.0 includes IPoIB RSS support for datagram mode. Try to upgrade your software to MOFED 2.0, then check your CPU utilization when running IPoIB datagram (echo datagram > /sys/class/net/ibX/mode).

Have you looked at SDP to just not use tcp all together? Has worked great for me a year or two ago
View ArticleRe: ConnectX-2: Enabling RSS (Receive Side Scaling) in IPoIB mode
