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.
