wasm-big-mult

big-mult

Extremely fast, low error, sampling based matrix multiplaction algorithm for giant matrices. Implemented in AssemblyScript and tested with as-pect;

Usage

• Import and stream the wasm module using the async function buildMultiplier.
• Run giantMult using the module you built.

import { giantMult, buildMultiplier } from "wasm-big-mult";
 
// Trivially small matrices just to show usage
const a = [[1, 2], [1, 2], [1, 2], [1, 2], [1, 2]];
const b = [[1, 2, 3, 4, 5], [1, 2, 3, 4, 5]];
const samples = 3;
 
buildMultiplier()
  .then(wasmModule => {
    console.log(giantMult(wasmModule, a, b, samples));
  })
  .catch(err => console.log(err));

Note

Functionality is not currently defined when the dimensions of a and b are not valid, the function will throw descriptive errors in future versions

Warnings

• Parcel does not support assemblyscript, please use webpack if you wish to use this package.
• Due to js memory limitations the biggest matrices supported right now are 1000x1000. WIth some improvements to way this package manages memory the cap will increase in the future.
