Porting a user-level communication architecture to NT: experiences and performance

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. 1 Introduction The primary goal of the SHRIMP project is to investigate how to design high-performance servers by leveraging commodity PC hardware and commodity PC software. A key research component is to design and implement a communication mechanism whose performance is competitive with or better than that of custom-designed multicomputers. The challenge is to achieve good communication performance without r...
