GPUComputePassEncoder: end() method

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The end() method of the GPUComputePassEncoder interface completes recording of the current compute pass command sequence.

Syntax

js

end()

Parameters

None.

Return value

None (Undefined).

Validation

The following criteria must be met when calling end(), otherwise a GPUValidationError is generated and the GPUComputePassEncoder becomes invalid:

Examples

In our basic compute demo, several commands are recorded via a GPUCommandEncoder. Most of these commands originate from the GPUComputePassEncoder created via GPUCommandEncoder.beginComputePass().

js

const BUFFER_SIZE = 1000;

// ...

// Create GPUCommandEncoder to encode commands to issue to the GPU
const commandEncoder = device.createCommandEncoder();

// Initiate render 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()]);

// ...
