Note 1: Windows HPC Server 2008 Compatibility with previous versions
All of the command-line tools in Windows Compute Cluster Server
2003 (such as Cluscfg for configuration, and
Clusrun for running commands remotely on one or
more nodes) are still included.
Windows HPC Server 2008 provides API-level compatibility for
applications integrated with Windows Compute Cluster Server 2003.
These applications might, however, require changes to run on Windows
Server® 2008. If you encounter problems running your application on
Windows Server 2008, you should consult your software vendor.
Windows HPC Server 2008 supports job submission from Windows
Compute Cluster Server 2003 clients, including the command-line
tools, the Compute Cluster Job Manager, and the COM APIs.
The Windows HPC Server 2008 client tools, including the cluster
administration console (HPC Cluster Manager), the job scheduling
console (HPC Job Manager), the command-line tools, and the APIs
cannot be used to manage or submit jobs to a Windows Compute Cluster
Server 2003 cluster.
Clusters that have Windows Compute Cluster Server 2003 nodes and
Windows HPC Server 2008 nodes are not supported.
Note 2: considerations
A side-by-side installation of Windows HPC Server 2008 and
Windows Compute Cluster Server 2003 on the same computer is not
supported. This includes the Windows HPC Server 2008 client
utilities.
The upgrade of a Windows Compute Cluster Server 2003 head node
to a Windows HPC Server 2008 head node is not supported.
The installation of HPC Pack 2008 adds the following server
roles to the head node:
DHCP
Windows Deployment Services
File Services
Network Policy and Access Services, which enables Routing
and Remote Access so that NAT services can be provided to the
cluster nodes.
