As part of its now usual advanced products launch strategy, NVIDIA is offering free test drives of its latest accelerator, the Tesla K40, via remote access. Scientists and engineers have the possibility of evaluating their own codes or testing already installed applications, among which AMBER, NAMD, GROMACS, and ACEMD. To do so, an on-line application has to be filled out, after which all reasonable requests should be eligible. A quick reminder: the K40 theoretically performs 40% better than the K20X thanks to a larger internal memory of 12 GB and the GPU Boost technology, which basically “overclocks” graphics processors on demand.
