Get CPU/GPU/memory information
I need to get any information about the CPU/GPU/memory.The number of cores, memory value, memory and cpu usage... I found a way to do this for IE:How to Use JavaScript to Find Hardware Information
solutions for other browsers I do not know. Any idea how to do it? maybe webgl has access to information about your computer? or flash? or any other technology?
Thank you very much
Answer
This code will print GPU infos an will list all info you can have with the performance object of this browser (there is no standard for the BOM so it changes for each browser).
<html>
<body>
<canvas id="glcanvas" width="0" height="0"></canvas>
<script>
var performance = window.performance || window.mozPerformance || window.msPerformance || window.webkitPerformance || {};
document.write("<br>");
for (var value in performance) {
document.write(value + "<br>");
}
document.write("<br><br><br>");
var canvas;
canvas = document.getElementById("glcanvas");
var gl = canvas.getContext("experimental-webgl");
document.write(gl.getParameter(gl.RENDERER) + "<br>");
document.write(gl.getParameter(gl.VENDOR) + "<br>");
document.write(getUnmaskedInfo(gl).vendor + "<br>");
document.write(getUnmaskedInfo(gl).renderer + "<br>");
function getUnmaskedInfo(gl) {
var unMaskedInfo = {
renderer: '',
vendor: ''
};
var dbgRenderInfo = gl.getExtension("WEBGL_debug_renderer_info");
if (dbgRenderInfo != null) {
unMaskedInfo.renderer = gl.getParameter(dbgRenderInfo.UNMASKED_RENDERER_WEBGL);
unMaskedInfo.vendor = gl.getParameter(dbgRenderInfo.UNMASKED_VENDOR_WEBGL);
}
return unMaskedInfo;
}
</script>
