Introduction

The Chapel is an open-source programming language designed for productive parallel computing at scale. The Chapel compiler is written in C and C++14. The backend is LLVM, written in C++. The goal of Chapel is to improve the programmability of parallel computers in general.

Installation

Basic

Variables

Variables are declared with the var keyword. Variable declarations must have a type, initializer, or both. 

     var myVariable1: int;
     writeln("myVariable1 = ", myVariable1);

const and param can be used to declare runtime constants and compile-time constants respectively. A const must be initialized in place, but can have its value generated at runtime. A param must be known at compile time. 

     const myConst: real = sqrt(myVariable2);
     param myParam = 3.14;
     writeln("myConst = ", myConst, ", myParam = ", myParam);
