Comparison to OCaml

If you come from OCaml or are a newcomer reading a tutorial written on OCaml, this guide's for you! But don't forget that reason-tools can convert between OCaml and Reason syntax on the fly.

Vim, Vundle and ConEmu on Windows

Let's start by getting it out on the table: Sublime Text is great, and version 3 should no longer be considered "abandonware" as of build 3065. Sublime Text served me very, very well over the years. That said, trying out new things is a major part of leveling-up, and in that vein Vim deserves a go. (And have you seen some of those thoughtbot guys flying around in Vim? It's awesome!)

Getting Vim up-and-running on your Windows machine doesn't have to be an all-day project. In this post, we'll walk through:

Installing gVim, which gives us both the "classic" command line version as well as the graphical version
Installing Vundle, the best way to handle Vim-enhancing packages
Installing ConEmu, a supercharged command line emulator for Windows

	program myalltoall
	!Program to show a simple implementation of a deadlock avoiding mpi loop among all processes which,
	!in principle, is similar to an alltoall loop. However, the main purpose of the technique shown here is to
	!properly reorder shortest (i.e., each process with just few others) non-blocking communication loops,
	!in order to alleviate the burden on the communication side (as each exchange is matched, everything
	!is exchanged very quickly). Here, it is tested against the the mpi_allreduce intrinsic with MPI_SUM
	!on a single real variable, but IT IS NOT a replacement for allreduce (nor alltoall or any other intrinsic).
