my biggest annoyance with LuaJIT is the lack of 64-bit addressing, and there's no easy fix for this. Mike Pall said he'd fix it in LuaJIT 3.0 (with an overhaul of the GC), whenever that'll be. http://hacksoflife.blogspot.com/2012/12/integrating-luajit-with-x-plane-64-bit.html http://hacksoflife.blogspot.com/2012/12/integrating-luajit-w... Edit: to clarify, this does not mean torch cant use more than 2GB, but native lua allocations cant be more than 2GB, so ffi-based or C based allocations (which is how torch tensors are allocated) have no such limits.

This is a big annoyance for me as well. I use jemalloc to make sure that my FFI allocations don't 'steal' this lower memory from my pure Lua allocations. It works great on Linux, but only so-so on OSX. http://www.canonware.com/pipermail/jemalloc-discuss/2014-February/000740.html http://www.canonware.com/pipermail/jemalloc-discuss/2014-Feb... https://gist.github.com/neomantra/9122165 https://gist.github.com/neomantra/9122165
