[VCL Cluster] Recommend budget Infiniband hardware?
#1
Hi,
I'm building a cluster, first with 3 PCs:
PC 1: My old PC , 2x HD6990 Intel i7 6 cores , 32GB Ram
PC 2: New, just built, 3x HD7970 AMD 8 cores, 16GB Ram
PC 3: New, just built, 3x HD7970 AMD 8 cores, 16GB Ram (Still building, not ready yet)

I'm trying to run a cluster with PC1 and PC2 at computer node, a VM by VirtualBox on PC1 as host (12GB Ram) , and it get only about ~6500Mb/s on SHA1. This is very poor performance, with 3x HD7970 only run at ~600Mb/s . HD 6990 running as about 1200Mb/s x 2 which is pretty OKAY (I think because it is in local host)

I think the problem is because I'm connecting them by an Asus RT-N56U router (no internet connection).

-Can you please suggest any budget InfiniBand hardward (LAN + Switch). Or any other possible solution.
Please recommend a few brand, as in New Zealand, I don't have much choice Sad

-My target is about maximum 15 cards HD7970 on 5 PCs.

And if it is possible, please share any guide how to setup as well. I'm totally newbie on InfiniBand Sad To tell the truth, only heard them when searching on VCL cluster.

Thank you very much.
