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 standardized 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 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
- module add mono/5.12.0
- module add mono/5.16.0.220
Compilation
The program would be compiled in the following way:
[username@login01 ~]$ module add mono/5.12.0 [username@login01 ~]$ mcs -out:cDEMO.exe cDEMO.cs
