WebJul 2, 2012 · Threads can compute their global index within an array of thread blocks by accessing the built-in variables blockIdx , blockDim, and threadIdx, which are assigned by the hardware for each thread and block. WebMay 23, 2024 · threadID is a misleading term in your example. The value calculated is actually an index into an array that the current thread will read or write. If your kernel is …
threadIdx.x is the x dimension of the thread identifier Thus ‘i’ will have values ranging from 0 to 511 that covers the entire array. If we want to consider computations for an array that is larger than 1024 we can have multiple blocks with 1024 threads each. Consider an example with 2048 array elements. See more A 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 … See more 1D-indexing Every thread in CUDA is associated with a particular index so that it can calculate and access memory locations in an array. Consider an … See more • Parallel computing • CUDA • Thread (computing) • Graphics processing unit See more CUDA operates on a heterogeneous programming model which is used to run host device application programs.
