Web30 jan. 2024 · rL352799: [CUDA] add support for the new kernel launch API in CUDA-9.2+. Summary Instead of calling CUDA runtime to arrange function arguments, the new API constructs arguments in a local array and the kernels are launched with __cudaLaunchKernel (). The old API has been deprecated and is expected to go away in … Web3 jun. 2024 · So here I go over the HIP-specific launch bounds and try to generalize them to cover CUDA, too. The long term goal is to eventually not need to resort to somewhat ad-hoc adaptations like the reduction of block size discussed in pytorch#8103 , but have good coverage of our kernels with launch bound annotations. the northman poster art https://sexycrushes.com
