native-wasm-c's Introduction

native-wasm-c

Compares performance of the single precision BLAS saxpy routine between WebAssembly (using AssemblyScript), TypeScript, C (Node.js addon) and nblas. Here is the reference implementation for the saxpy routine.

Files:

  • src/saxpy.ts – TypeScript implementation
  • c/saxpy.cc – C implementation
  • assembly/saxpy.ts – AssemblyScript implementation
  • assembly/index.ts – Entry point for AssemblyScript compilation
npm install
npm run build
npm test

Test output:

ts:empty x 862,129,693 ops/sec ±0.68% (91 runs sampled)
ts x 36.17 ops/sec ±3.34% (48 runs sampled)
wasm:empty x 53,163,899 ops/sec ±0.83% (93 runs sampled)
wasm x 12.46 ops/sec ±2.25% (35 runs sampled)
wasm optimized:empty x 52,309,689 ops/sec ±1.73% (88 runs sampled)
wasm optimized x 13.48 ops/sec ±0.31% (37 runs sampled)
