Vectorize.js

Vectorize.js is a javascript library for automatically vectorizing javascript using Mozilla's SIMD.js. Vectorize.js works by converting a function to a string, parsing it with Esprima, transforming it to use SIMD vectors, and regenerating the code using Escodegen.

Example Usage

Have a function you want to vectorize? It's as easy as this:

vectorFunction = vectorize.me(scalarFunction);

Currently Vectorize.js supports the following language features for operating on vectors:

• Binary Operators: +, -, *, /, <, <=, ==, >=, >
• Unary Operators: ++, --
• Reductions: +, -, *, /
• Nested loops

We are currently in the process of adding support for:

• Conditionals and Conditional Expressions.
• Inlining and vectorizing function calls.
• min/max operators/reductions.

Vectorize.js relies on the following libraries to process and transform the Javascript:

• Esprima
• Escodegen
• Estraverse
• Esrecurse

Disclaimers

Javascript is a complicated language with lots of features and hence lots of edge cases! Vectorize.js tries its best to not break your functions but we make no guarantees.
