Why not combine the good parts of atomics and the good parts of the speed of local variables sitting in the CPU register? Here we are:
// worker.jslet sharedMem;addEventListener('message', ({data}) => { //console.log(data); if(data.message == 'sab') { sharedMem = data.memory; console.log('Memory ready'); } if(data.cmd == 'start') { console.log('Iterations ready'); startCounting(data.iterations); }});function startCounting(limit) { const arr = new Uint32Array(sharedMem); let count = 0; for(let i=0;i<limit;i++) { count += 1; } Atomics.add(arr, 0, count); postMessage('done')}
Here, from our last implementation, we took Atomics.add out of the loop to avoid calling it a billion times. Instead, we performed the work assigned to ...
