Interesting! The C6145s have dual IO hubs per node which should give better HBA->CPU performance than the 6100 with so many GPUs attached per node. That’s only true though if the NUMA related issues are sorted out (ie making sure that threads are properly matched to cores with the right IOH/GPU attached). I hope they publish some benchmarks on this setup with things like NAMD STMV with differing numbers of GPUs.

According to their detailed specs, Forge is based on AMD Opteron Magny-Cours 6136 2.4 GHz dual-socket eight-core. We regret the error.

Doesn’t the Poweredge C6145 have the opteron 6100′s instead of xeons? I think this is a typo in the story, it could mean Xeon 5600′s on Poweredge C6100′s instead. I just got a bunch of these 6100′s. That’s why i noticed this. Thanks
