Synchronize cpu with gpu
WebSep 27, 2024 · Compute it in GPU. To ask GPU’s CUDA to perform the same computation, I simply replace .to(‘cpu’) to .cude(). Besides, considering the operations in CUDA are asynchronous, I also need to add a synchronization statement to ensure printing the used time after all CUDA tasks are done. WebTo solve this issue, we need to explicitly synchronize all threads in a block, so that memory operations are also finalized and visible to all. To synchronize threads in a block, we use …
