There are two ways to go about debugging MPI applications using Microsoft Visual Studio. There’s the easy way, and the hard way. Unfortunately for many, the easy way is only available for the professional versions of Microsoft Visual Studio. If you right click on your project, select properties, select the debugging page, you can simply choose to use the MPI Cluster Debugger. If you don’t have a professional version of visual studio, don’t panic, you can still debug your applications.

MPI, or Message Passing Interface, is a library of functions for C,C++, and even Fortran. The purpose of this library is for you to easily create an application that fully utilizes multiple processors. Not only can you utilize multiple processors with MPI, but you can even run a single instance of a single application across multiple computers with MPI. Continue reading ‘What is MPI?’ »

The main strong point of CUDA is highly parallel number crunching. Fortunately, this is a very common type of problem encountered in many high performance computing problems. Here is a list of some example applications which have been created using CUDA to achieve maximum performance that is simply not possible on a CPU alone.

CUDA stands for Compute Unified Device Architecture, and is an extension of the C programming language and was created by nVidia. Using CUDA allows the programmer to take advantage of the massive parallel computing power of an nVidia graphics card in order to do general purpose computation. Continue reading ‘What is CUDA?
