The two newest Volta nodes have 40 cores so the number of cores requested per GPU should be adjusted upwards accordingly, i.e. you can use 5 CPU cores per GPU. They also have NVLINK, which can provide huge benefits for situations where memory bandwidth between GPUs is the bottleneck. | The two newest Volta nodes have 40 cores so the number of cores requested per GPU should be adjusted upwards accordingly, i.e. you can use 5 CPU cores per GPU. They also have NVLINK, which can provide huge benefits for situations where memory bandwidth between GPUs is the bottleneck. If you want to use one of these NVLINK nodes, you should request it directly by adding the <tt>constraint=cascade,v100</tt> parameter to the job submission script. | ||
