The end() method of the GPUComputePassEncoder interface completes recording of the current compute pass command sequence.
end()None.
None (undefined).
The following criteria must be met when calling end(), otherwise a GPUValidationError is generated and the GPUComputePassEncoder becomes invalid:
GPUComputePassEncoder is open (i.e., not already ended via an end() call).pushDebugGroup() calls made on this encoder have a corresponding popDebugGroup() call before end() is called.In our basic compute demo, several commands are recorded via a GPUCommandEncoder. Most of these commands originate from the GPUComputePassEncoder created via GPUCommandEncoder.beginComputePass().
const BUFFER_SIZE = 1000;
// …
// Create GPUCommandEncoder to encode commands to issue to the GPU
const commandEncoder = device.createCommandEncoder();
// Initiate compute pass
const passEncoder = commandEncoder.beginComputePass();
// Issue commands
passEncoder.setPipeline(computePipeline);
passEncoder.setBindGroup(0, bindGroup);
passEncoder.dispatchWorkgroups(Math.ceil(BUFFER_SIZE / 64));
// End the render pass
passEncoder.end();
// Copy output buffer to staging buffer
commandEncoder.copyBufferToBuffer(
output,
0, // Source offset
stagingBuffer,
0, // Destination offset
BUFFER_SIZE,
);
// End frame by passing array of command buffers to command queue for execution
device.queue.submit([commandEncoder.finish()]);
// …
