How does a Windows-based compute cluster compare with a cluster running UNIX or Linux?
A. There is little substantive difference, but UNIX-based solutions should be fully ported to Windows to realize the full benefits of the Windows operating system. There are several differences between UNIX-based operating systems and Windows. For example, I/O operations and threading are different on UNIX-based systems than they are on Windows. I/O intensive applications will benefit from using Windows native I/O APIs rather than UNIX style I/O APIs.
