The setPipeline() method of the
{{domxref("GPUComputePassEncoder")}} interface sets the {{domxref("GPUComputePipeline")}} to use for this compute pass.
setPipeline(pipeline)
pipeline
None ({{jsxref("Undefined")}}).
In our basic compute demo, several commands are recorded via a {{domxref("GPUCommandEncoder")}}. Most of these commands originate from the {{domxref("GPUComputePassEncoder")}} created via beginComputePass(). The setPipeline() call is used as appropriate to set the pipeline to use for this pass.
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()]);
// …
