TY - JOUR AU - Vogels, W. AB - U-Net: A User-Level Network Interface Computing for Parallel and Distributed Thorsten von Eicken, Anindya Basu, Vineet Buch, Science and Werner Vogels Department of Computer University NY 14853 Cornell Ithaca, Abstract The U-Net communication architecture prowdes processeswith a virtual view of a network interface to enable userIevel accessto high-speed communication dewces. The architecture, implemented on standard workstations using offthe-shelf ATM communication hardware, removes the kernel from the communication path, while stall prowdmg full The model presented by U-Net allows for the construction of protocols at user level whose performance is only limited by the capabilities of network. The architecture is extremely flexible in the sensethat traditional protocols like TCP and UDP, as well as novel abstractions like Active Messages can be implemented efficiently. AU-Net prototype on an 8node ATM cluster of standard workstations offers 65 microseconds round-trip latency and 15 Mbytes/see bandwidth. It achieves TCP performance at maximum network bandwidth and demonstrates performance equivalent to Meiko CS-2 and TMC CM-5 supercomputers on a set of Split-C benchmarks. 1 Introduction The increased shifted availability of high-speed local area networks from path has the bottleneck of network in local-area fabrics communication software the limited by bandwidth messages to the traversed ends.
