Description
What is wrong?
The random number distribution is Normal instead of Uniform[0,1]
Where does it happen?
Ex. In GPU.js when I run Math.random inside a gpu.createKernel(function() in Node.js on my pc windows 10 and Nvidia GPU
NB If mode is set to cpu, all else equal, the numbers are Unifom
How do we replicate the issue?
const { GPU } = require('gpu.js');
const gpu = new GPU({ mode: 'gpu' });
const nobs=10000;
const kernel = gpu.createKernel(function() {
const y=Math.random();
return y;
}, { output: [nobs] });
const data = kernel();
How important is this (1-5)?
5
Expected behavior (i.e. solution)
the data should be uniform
Other Comments
Probably, in the plugin you should have chosen nrandom instead of n4random.
