The second service pack to the HPC Pack 2008 R2 software is now available!
This update includes a number of great new features, including
For more information on those, and other, new features available in Service Pack 2 please see our documentation on TechNet.
The single SP2 installer applies to both Express and Enterprise installations, as well as the standalone 'Client Utilites' and 'MS-MPI' packages. You can download it from the Microsoft Download Center.
An important note is that this service pack can not be uninstalled by itself. Uninstalling the service pack will also uninstall the HPC Pack itself, so you'll need to take a full backup (including the sql databases) before installation if you want to be able to 'roll back.'
If you do not have an HPC Pack 2008 R2 cluster, you can download a free Windows HPC Server 2008 R2 evaluation version. Before you install, you can try out the new Installation Preparation Wizard which can help analyze your environment for common issues and provide some best practice guidance to help ensure an easy HPC cluster setup.
