</span> Huhh? I don't think one can just run on the CPU's of this machine. You are throwing away 90+ percent of the machine! Did someone in authority tell you it is fine to just use the CPUs in this machine? Hell, I need to talk to them :-)<br>

They will probably have about 30K (2D linear FE) equations per 40 Tflop node. 10% (4 Tflops) is too much resources for 30K equations as it is. No need to try utilize the GPU as far as I can see. </div></div></div></div>
