I made this little code to try perf on a method :

var gpu = new GPU();

var add = gpu.createKernel(function(){
    var a = 0;
    for(var i=0; i < 100000000000; ++i)
    {
        if(i < 100)
        {
            a = a + 1;
        }else{
            break;
        }
    }
    return a;
}).dimensions([1]);

function bench()
{
    add.mode("GPU");
    console.time("GPU");
    console.log(add());
    console.timeEnd("GPU");

    add.mode("CPU");
    console.time("CPU");
    console.log(add());
    console.timeEnd("CPU");
}

bench result :

bench();
GPU: 107.860ms
CPU: 3.080ms
bench();
GPU: 2.212ms
CPU: 2.339ms
bench();
GPU: 1.749ms
CPU: 2.439ms
bench();
GPU: 1.607ms
CPU: 2.013ms
bench();
GPU: 1.963ms
CPU: 2.250ms

@PicoCreator we already have loops with variables

var add = gpu.createKernel(function(){
    var a = 0; var b = 100;
    for(var i=0; i < b; i++)
    {
        a = a + 1;
    }
    return a;
}).dimensions([1]).loopMaxIterations(100000000000);

function bench()
{
    add.mode("GPU");
    console.time("GPU");
    console.log(add());
    console.timeEnd("GPU");

    add.mode("CPU");
    console.time("CPU");
    console.log(add());
    console.timeEnd("CPU");
}

from gpu.js.

@fuzzie360 bows

@Drulac, would that be good enough? : Now you just need to be able to create fixed arrays in GPU/JS code right?

from gpu.js.

This doesn't work I think (I havent the time to test)

var add = gpu.createKernel(function(b){
    var a = 0;
    for(var i=0; i < b; i++)
    {
        a = a + 1;
    }
    return a;
}).dimensions([1]).loopMaxIterations(100000000000);

function bench()
{
    add.mode("GPU");
    console.time("GPU");
    console.log(add(100));
    console.timeEnd("GPU");

    add.mode("CPU");
    console.time("CPU");
    console.log(add(100));
    console.timeEnd("CPU");
}
