WebJan 31, 2024 · One of the staples of CUDA-enabled GPU computing was the lockstep fashion in which 32 threads in a warp execute instructions. Is this still the case in the more recent versions of CUDA? If this is not the case, can you please share with me good links that point me to where I need to go read/get educated about this? WebNov 25, 2012 · 1. You still need __syncthreads () even if warps are being executed in parallel. The actual execution in hardware may not be parallel because the number of cores within a SM (Stream Multiprocessor) can be less than 32. For example, GT200 architecture has 8 cores in each SM, so you can never be sure all threads are in the same point in …
WebSummary. Shared memory is a powerful feature for writing well optimized CUDA code. Access to shared memory is much faster than global memory access because it is located on chip. Because shared memory is shared by threads in a thread block, it provides a mechanism for threads to cooperate. WebFeb 27, 2024 · CUDA reserves 1 KB of shared memory per thread block. Hence, the A100 GPU enables a single thread block to address up to 163 KB of shared memory and GPUs with compute capability 8.6 can address up to 99 …

WebNov 25, 2016 · Threads in a Block are grouped in Warps of 32 Threads and warps are executed parallel. Warps from different Blocks can by executed on one SM. Can threads from different blocks be in the same warp? How many threads are executed on one SP? Intuitively I would say 1. If so, then 192/32= 6 Warps maximum parallel executed on the …
WebSep 6, 2024 · A group of threads is called a CUDA block. CUDA blocks are grouped into a grid. A kernel is executed as a grid of blocks of threads (Figure 2). Each CUDA block is executed by one streaming multiprocessor (SM) and cannot be migrated to other SMs in GPU (except during preemption, debugging, or CUDA dynamic parallelism).
