Hello, We are currently in the process of buying several servers which will include GPU accelerato. Because of the price / performance balance in case of our limited funds we have to choose between K40 and K20X tesla accelerators. Initially, we wanted 2 GPU's/node (dual Xeon E5-2680v2 2.8GHz) but as expected the funds were enough for only 1 K40 per node. Instead, it may be feasible to be able to put 2 K20x in each node.
We tried to make a test through NVidia TestDrive but the things take too long. (still :) ) My question is if anybody can make a suggestion of which should be more convenient for GROMACS performance: 2 x K20x versus 1 K40 per node. In the absence of any testing opportunity any suggestion is extremely valuable to us. Many thanks! *Dr. Andrei Neamtu, PhD, Lecturer Department of Physiology "Gr. T.
