WebFeb 4, 2011 · At runtime, threads are divided into groups and each group (warp) includes 32 threads which run together. Each MP (only 8 cores) could have as many as 32 warps, ie, 1024 threads (!). There seems no way that 1024 threads run on only 8 … WebOne full warp consists of a bundle of 32 threads with consecutive thread indexes. The threads in a warp are then processed together by a set of 32 CUDA cores. This is analogous to the way that a vectorized loop on a CPU is chunked into vectors of a fixed size, then processed by a set of vector lanes.
