Cupy fallback to cpu
WebSep 11, 2024 · An alternative approach would be to get some control over the work submission. Create a wrapper work submission function, which 1. acquires global lock 2. launches work 3. launch callback to release global lock. If you can acquire the global lock from the GUI thread, launch there. Else, use CPU. – Robert Crovella Sep 11, 2024 at 16:27 WebJan 12, 2024 · Cupy is much faster when reduction is performed on one axis at a time. In stead of: x.sum () prefer this: x.sum (-1).sum (-1).sum (-1)... Note that the results of these computations may differ due to rounding error. Here are faster mean and var functions:
