Fantastic news! Mellanox has released the beta 2 version of their WinIB 1.4 stack, which works with HPC Server 2008 beta 2 and has Network Direct providers for their latest ConnectX cards. The results announced at ISC 08 are outstanding:
- 2 microseconds' latency
- 2 GB/s throughput
Another outstanding result for HPC Server 2008 is the Umea cluster, at n. 39 in the Top 500 list:
- 46.04 TFlops
- 85.6% efficiency
Hats off to the Network Direct team. Now Windows HPC Server 2008 plays with the big boys :-)
