Programming Details

C# is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming. Although originally developed by Microsoft for their own platform it has been standardised and a Linux version called MONO has been developed and matured.

The Mono project provides an open-source C# compiler, a complete open-source implementation of the Common Language Infrastructure including the required framework libraries as they appear in the ECMA specification, and a nearly complete implementation of the Microsoft proprietary .NET class libraries up to .NET 3.5. Note at this time Windows Presentation Foundation (WPF) does not exist.


Programming example

using System;
using MPI;

class Ring
{
    static void Main(string[] args)
    {
        using (new MPI.Environment(ref args))
        {
            Intracommunicator comm = Communicator.world;
            if (comm.Rank == 0)
            {
                // program for rank 0
            }
            else // not rank 0
            {
                // program for all other ranks
            }
        }
    }
}


Modules Available

The following modules are available:

  • module add mono/4.4.1


Compilation

The program would be compiled in the following way:

[username@login01 ~]$ module add mono/4.4.1
[username@login01 ~]$ mcs -out:cDEMO.exe cDEMO.cs
