What is Torch? Torch is a scientific computing framework with wide support for machine learning algorithms that puts GPUs first. It is easy to use and efficient, thanks to an easy and fast scripting language, LuaJIT, and an underlying C/CUDA implementation. A summary of core features: a powerful N-dimensional array lots of routines for indexing, slicing, transposing, … amazing interface to C, via

FAQ Are you really porting the entire Lua VM? Yes: The entire Lua 5.2.2 codebase written in C is compiled to JavaScript here, including a full incremental GC and everything else. It fits in 200K of gzipped JavaScript. How can a VM running in a VM be fast? Lua is implemented in portable C. It is possible to run C compiled to JavaScript at speeds approaching that of a native build (using the asm.js
