Intensive calculation. WASM? WEBGL?

One of my app needs a run a small calculation that takes 1 min on a classic browser.

It there a way with Meteor/Cordova to access the GPU and process a specific function using all the potential of the device?

I think Webassembly is disabled in iOS? Does Crosswalk help in this case?

Maybe something like this helps? https://hackernoon.com/introducing-gpu-js-gpu-accelerated-javascript-ba11a6069327

Looks very good thanks.Do you know if it works on mobile?

I don’t see any problem since its server side anyway

Ok thanks. I should have specified that I am looking for client slide.

Any equivalent to Metal on iOS?
