GPUQueue: submit() method

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

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

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Note: This feature is available in Web Workers.

The submit() method of the GPUQueue interface schedules the execution of command buffers represented by one or more GPUCommandBuffer objects by the GPU.

Syntax

js
submit(commandBuffers)

Parameters

commandBuffers

An array of GPUCommandBuffer objects containing the commands to be enqueued for processing by the GPU. The array must not contain duplicate GPUCommandBuffer objects — each one can only be submitted once per submit() call.

Return value

None (Undefined).

Validation

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

Examples

In our basic render demo, a number of commands are recorded via a GPUCommandEncoder:

js
// ...

// Create GPUCommandEncoder
const commandEncoder = device.createCommandEncoder();

// Create GPURenderPassDescriptor to tell WebGPU which texture to draw into, then initiate render pass

const renderPassDescriptor = {
  colorAttachments: [
    {
      clearValue: clearColor,
      loadOp: "clear",
      storeOp: "store",
      view: context.getCurrentTexture().createView(),
    },
  ],
};

const passEncoder = commandEncoder.beginRenderPass(renderPassDescriptor);

// Draw a triangle

passEncoder.setPipeline(renderPipeline);
passEncoder.setVertexBuffer(0, vertexBuffer);
passEncoder.draw(3);

// End the render pass

passEncoder.end();

// ...

The commands encoded by the GPUCommandEncoder are recoded into a GPUCommandBuffer using the GPUCommandEncoder.finish() method. The command buffer is then passed into the queue via a submit() call, ready to be processed by the GPU.

js
device.queue.submit([commandEncoder.finish()]);

Note: Study the WebGPU samples to find more queue examples.
