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 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 } } } }
using System; using System.Linq; using System.Threading; using System.Threading.Tasks; using System.Collections.Concurrent; class MatrixCalc { static void Main(string[] args) { Random rnd = new Random(); int size = int.Parse(args[0]); int maxVal = 255; double[,] m1 = new double[size, size]; double[,] m2 = new double[size, size]; double[,] res = new double[size, size]; for (int i = 0; i < size; i++) { for (int j = 0; j < size; j++) { m1[i, j] = rnd.Next(0, maxVal); m2[i, j] = rnd.Next(0, maxVal); } } int para = Environment.ProcessorCount; var watch = System.Diagnostics.Stopwatch.StartNew(); Parallel.For(0, para, worker => { var max = size * (worker + 1) / para; var start = size * worker / para; for (int row = start; row < max; row++) { for (int col = start; col < max; col++) { double temp = 0; for (int ele = start; ele < max; ele++) { temp += m1[row, ele] * m2[ele, col]; } res[row, col] = temp; } } }); watch.Stop(); var elapsedMs = watch.ElapsedMilliseconds; System.Console.WriteLine(elapsedMs); } }
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
