WebExplanation. SMyBuffer is a stack of elements ( data []) with a count of the current number of elements. When a certain condition is met, the compute shader increments the count atomically. This operation returns the previous index which is used to index data [] to store the new element. This guarantees that no two shader invocations overwrite ... WebHere, each of the N threads that execute VecAdd() performs one pair-wise addition.. 2.2. Thread Hierarchy . For convenience, threadIdx is a 3-component vector, so that threads can be identified using a one-dimensional, two-dimensional, or three-dimensional thread index, forming a one-dimensional, two-dimensional, or three-dimensional block of threads, …
