wait (GPUDevice)

Wait for GPU calculation to complete

Syntax

wait(gpudev)


Description

wait(gpudev) blocks execution in MATLAB^® until the GPU device identified by the GPUDevice object gpudev completes its calculations. This can be used before calls to toc when timing GPU code that does not gather results back to the workspace. When gathering results from a GPU, MATLAB automatically waits until all GPU calculations are complete, so you do not need to explicitly call wait in that situation.
