Wait Sample Clauses

Wait. In the final phase, one simply waits for the kernel invoked in the first phase to finish its computations (blocking call). The iterative compute-and-copy processing of the chunks can be implemented via two (OpenCL) command queues [13]: For the first chunk, phase (1) and (3) are instantiated via command queue A, whereas the copy process (2) is instantiated via command queue B (non-blocking for both (1) and (2)). For the second chunk, phases (1) and (3) are instantiated via command queue B and (2) via command queue A. This process continues until all chunks have been processed. In essence, the use of two command queues allows the copy phase (2) to run in parallel with the brute-force computation phases (1) and (3).
