The Microsoft HPC team is pleased to announce that Service Pack 1 (SP1) is now available!
This release has improvement to the reliability of the cluster, increased performance of certain operations, increased security, and a more robust disaster recovery experience.
You can find the update at:

It is suggested that this be installed on all machines in your cluster as well as workstations that you have installed the 'client utilities' on.
Along with the application update there is an updated version of the SDK available at:
http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=3fe15731-b1b6-42de-b278-5ccd46c0863b The SDK is not a 'patch' it is a full install of the SDK, so you need to uninstall the previous HPC Pack 2008 SDK from your machine (via the 'Add/Remove Programs' or 'Uninstall a program' Control Panel, depending on your OS)
Both of these supercede the other post-RTM fixes that we have previously released for each product.
