IBM and Mellanox publish first RoCE-based STAC-M2 results

Audited STAC-M2 Benchmark of IBM LLM on an IBM-BNT G8264 switch, using IBM x3550 servers and Mellanox MNPH29C-XTR ConnectX®-2 EN with RoCE

STAC has just released an audited STAC-M2(TM) Benchmark of the following stack:

- IBM WMQ Low Latency Messaging v2.4.0.2
- Red Hat Enterprise Linux AS 5.5
- 2 x Quad-Core Intel Xeon X5570 2.93 GHz
- IBM x3550 M2 Model Servers
- Mellanox MNPH29C-XTR ConnectX®-2 EN with RoCE
- IBM-BNT G8264 10Gb/40Gb Ethernet Switch

Using standard Ethernet and RoCE protocols, at the base message rates set by the specs, the mean latency of the solution did not exceed 7 microseconds, while standard deviation of latency was measured at 1 microsecond. At the highest tested rate of 2.3 million messages/second, the mean latency of the solution was just 13 microseconds while the standard deviation of latency was measured at 2 microseconds.
