Chapel is a parallel programming language designed for productivity at scale.

If you’re new to Chapel, you may want to:

• read a short introductory blog article
• read a more in-depth overview paper
• watch a video or browse the slides for a recent Chapel overview talk
• download the release
• browse six versions of “Hello, world!” in Chapel and learn how to trivially write distributed-memory computations like this

  use CyclicDist;             // use the Cyclic distribution library
  config const n = 100000;    // override default using ./a.out --n=<val>
  
  forall i in {1..n} dmapped Cyclic(startIdx=1) do
    writeln("Hello from iteration ", i, " of ", n, " running on node ", here.id);
