1) Message boards : News : New Poll Regarding GPU Application of N-Body (Message 70999) Posted 22 Jul 2021 by Ironslug Post: My current AMD GPUs complete a Separation 1.46 WU in about 2.5 minutes. My 16-Core AMD CPU takes approximately 57 minutes to complete a single WU. If you are suggesting the adoption of a GPU implementation that will keep my GPU tied up for nearly an hour to only complete only one WU I would consider it a considerable waste of power and efficiency. Please correct me if I'm missing something here, but I'm failing to see advantage in throughput or efficiency. Both CPU and GPU tasks are similar computational size (approximately 42.6 GFLOPs) and my GPUs are each powering through 24-plus WUs and hour. I run several projects and at the moment MilkyWay@home is primarily a GPU-focused task for me precisely because of the efficiency of the GPU work. I suppose that I will have to wait until you actually release your GPU product to test it live, but if I lose the efficiency I'm presently estimating, I will likely have to push my GPUs into other distributed-science projects.
