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/5.2.0
Compilation
The program would be compiled in the following way:
[username@login01 ~]$ module add mono/5.2.0 [username@login01 ~]$ mcs -out:cDEMO.exe cDEMO.cs
