Maximum threads per block cuda

http://home.ustc.edu.cn/~shaojiemike/posts/cudaprogram/ WebIf this factor is limiting active blocks, occupancy cannot be increased. For example, on a GPU that supports 64 active warps per SM, 8 active blocks with 256 threads per block (8 warps per block) results in 64 active warps, and 100% theoretical occupancy.

cuda - maximum number of threads per block - Stack Overflow

WebThe number of thread blocks in a cluster can be user-defined, and a maximum of 8 thread blocks in a cluster is supported as a portable cluster size in CUDA. Note that on GPU hardware or MIG configurations which are too small to support 8 multiprocessors the maximum cluster size will be reduced accordingly. WebEarly CUDA cards, up through compute capability 1.3, had a maximum of 512 threads per block and 65535 blocks in a single 1-dimensional grid (recall we set up a 1-D grid in this code). In later cards, these values increased to 1024 threads per block and 2 31 - 1 blocks in a grid. It’s not always clear which dimensions to choose so we created ... christian hartleb
