Debugging MPI Applications on an HPC Cluster

Visual Studio 2010

With the MPI Cluster Debugger, you can debug parallel applications that are running on a Windows® HPC Server 2008 cluster and that communicate through Microsoft® Message Passing Interface (MPI). The MPI Cluster Debugger extends the Microsoft remote debugger functionality, simplifying the process of debugging multiple cooperating processes that are running on a remote cluster.

The MPI Cluster Debugger does the following:

  • Deploys your application files to the cluster nodes

  • Deploys any additional files that you specify

  • Launches the remote debugger on each node that is used for the debugging session

  • Cleans up after the debugging session ends

In this section

Walkthrough: Launching the MPI Cluster Debugger in Visual Studio 2010

Describes how to set up and launch an MPI Cluster Debugger session on your local computer and on a Windows HPC Server 2008 cluster. This walkthrough includes the steps and the sample code that you need to create an application that uses MPI, Open Multi-Processing (OpenMP), and Parallel Patterns Library (PPL) application programming interfaces (APIs).
