I saw a post recently with someone saying something to the effect of my Ryzen can run 32 WUs in the time it takes GPU to run run one WU. (I can't find it now.) I think it may be a false equivalence to compare WUs per unit time for a CPU to a GPU. As I understand it using a GPU is for parallel processing. I wonder if Light Curves solved per hour wouldn't be a better comparison. I don't know what's inside a WU but I suspect a CPU WU may have one or a few Light Curves to solve whereas a GPU WU may have dozens. A photon for your thoughts. |

Each day some of my computers stop running Linux 102.15 GPU WUs. Yet Tasks by Application, with only a single line, says there are over 255000 WUs available. With a couple dozens aps that could mean anything. How can I know A@H has run out of my flavor? Is there some other rule that cuts me off, e.g. maximum number of WUs to a computer per day? |
