WebNov 15, 2011 · CUDA Threads Now that we’ve seen the specific architecture of a Fermi GPU, let’s analyze the more general CUDA thread execution model. Each kernel function is executed in a grid of threads. This grid is divided into blocks also known as thread blocks and each block is further divided into threads. Cuda Execution Model WebThe CUDA analogs of threadid and nthreads are called threadIdx and blockDim, respectively; one difference is that these return a 3-dimensional structure with fields x, y, and z to simplify cartesian indexing for up to 3-dimensional arrays. Consequently we can assign unique work in the following way:

WebOnce a kernel is launched, the CUDA runtime system generates the corresponding grid of threads. As discussed in the previous section, these threads are assigned to execution resources on a block-by-block basis. In the current generation of hardware, the execution resources are organized into Streaming Multiprocessors (SMs). WebThe threads are executed inside the blocks. Threads and blocks can be one, two, and three dimensional, and they have an index space, as indicated in Fig. 3. In order to launch a kernel, there...

WebThe variable id is used to define a unique thread ID among all threads in the grid. The if statement ensures that we do not perform an element-wise addition on an out-of-bounds array element. In this program, blk_in_grid equals 4096, but if thr_per_blk did not divide evenly into N, the ceil function would increase blk_in_grid by 1.
