If I’ve tested HPC software to run on Windows Server 2003 64-bit Standard Edition, should I test separately on Windows Compute Cluster Edition?
A. Windows Server 2003 Compute Cluster Edition (CCE) and Windows Server 2003 64-bit Standard Edition have the same code base and therefore, you do not need to re-test the HPC applications on CCE if you’ve already tested them on Windows Server 2003 64-bit Standard Edition. Patches and service packs are also the same across the 64-bit versions of Windows Server 2003 Standard, Enterprise and Compute Cluster editions. Please note that Windows Server 2003 Compute Cluster Edition has a different code base than Windows Server 2003 R2.
