WebIn the context of CUDA, stream refers to a single operation sequence on a GPU device. Every CUDA kernel is invoked on an independent stream; not always true for other … unless you use streams and some other constructs, all of your cuda calls (kernels, cudamemCpy, etc.) will be issued in the default stream and they will be blocking (will not begin until previous cuda calls complete). As long as you don't switch streams, cudaMemcpy will not return control to the CPU thread until it is complete. digital exclusion meaningWebApr 13, 2024 · This work’s second contribution is applying these ideas to improve the synchronization-free resolution kernel presented in [10, 12].
