re: Achieve higher InfiniBand performance with on-load processing

Price and performance are the bottom line criteria for on-load vs. off-load choices in InfiniBand (IB). For transaction processing where roundtrip latency is a primary driver, one needs to look at the total cost of deploying either on-loaded or off-loaded setup and compare that against much lower cost version of Cat6A 10Gig fabric with off-load engines (TOE/POE). A good majority of the clusters are still using Cat6/6A fabric, often with no off-loading. If they can show matching performances in latency-sensitive applications, then it doesn't matter which version of IB is better! For throughput applications (like Ansys/CFD cited), it hardly matters whether your latency is a few milliseconds higher, it is more a bandwidth issue! Dr.MP Divakar
