Project Picasso - a multi-threaded runtime for Nim

"Good artists borrow, great artists steal." -- Pablo Picasso

Introduction

The Nim destructors and new runtime were introduced to provide GC-less path forward for Nim libraries and applications where it made sense. One of their explicit use case is making threading easier.

mratsim

import
  # STD lib
  os, strutils, threadpool, strformat
  # bench
  # ../wtime

# Using Nim's standard threadpool
# Compile with "nim c --threads:on -d:release -d:danger --outdir:build benchmarks/fibonacci/stdnim_fib.nim"
#
# Note: it breaks at fib 16.
