WebFeb 24, 2009 · A block is made up of warps. A warp is what executes on each SM at any given timestep. Jamie_K February 24, 2009, 8:15am 3 Shared memory is shared among all threads in a block. Synchronization occurs at the block level. So the block is the ‘scope’ within which sets of threads can communicate. WebCUDA C++ supports such collective operations by providing warp-level primitives and Cooperative Groups collectives. The Cooperative Groups collectives ( described in this previous post ) are implemented on top of the warp primitives, on which this article focuses. Part of a warp-level parallel reduction using shfl_down_sync ().

WebA thread block is a programming abstraction that represents a group of threads that can be executed serially or in parallel. For better process and data mapping, threads are grouped into thread blocks. The number of threads varies with available shared memory.
