<p>Dear QE users,<br>
</p>
I used to run QE on individual server and the computation speed is
quite limited.<br>
<br>
I am planning to build a small cluster with Intel CPUs and Nvidia
GPUs dedicated to QE and the cluster will be used by a few people
within the research group.<br>
<br>
The networking hardware that I already have: <br>
(1) Mellanox ConnectX-2 VPI Dual Port HCA Infiniband QDR adapter on
each server, <br>
(2) Mellanox 4036E 36 Port QDR switch, <br>
(3) 4 identical servers with same CPUs, memory and GPUs as computing
nodes, <br>
(4) QDR copper cables.<br>
<br>
My questions are: <br>
(1) how to configure the infiniband network on OpenSuSE 13.2?<br>
(2) how to compile QE to make use of the infiniband hardware?<br>
(3) how to compile and run GPU (pw-gpu.x) across the cluster?<br>
<br>
Thank you,<br>
Rolly<br>
