KissThreading.jl

This package is WIP and not fully tested. Use with care (tmap! should be safe to use).

Simple patterns supporting working with threads in Julia. Functionalities:

• tmap!, tmapreduce functions. They are designed for relatively expensive mapping f;
• trandjump and TRNG are for random number generators ready for threading
• getrange is a function returning a range of indices to traverse in a given thread it is designed for cases when we handcode loop inside @threads macro (usually when mapping f is cheap and e.g. can benefit from @simd); see test/summation.jl for example usage

Comparison of performance tmap! threading with copied random number generators and standard @Threading.threads. Tests run on 16 core AWS c4.4xlarge instance by running src/runtests.sh. We measure time using @time so tmap! has more of precompilation overhead reported.
