Abstract:

This paper describes our experiences in porting the VMMC user-level communication architecture from Linux to Windows NT. The original Linux implementation required no operating system changes and was done entirely using device drivers and user-level libraries. Porting the Linux implementation to NT was fairly straightforward and required no kernel modifications. Our measurements show that the performance of both platforms is fairly similar for the common data transfer operations because they bypass the OS. But Linux performs better than NT on operations that require OS support.
