How Applications Influence Systems, and Vice Versa

Date: October 07, 1993

Abstract: Interesting things can happen when systems designers take the time to study the properties of real applications. Careful attention to application properties can lead to new ideas in systems, as well as better applications. This talk describes some recent results from parallel systems researchers at Carnegie Mellon that are a direct result of this synergy between systems and applications: the notion of direct access to programmable connections, a new pipelined FFT algorithm for iWarp that outperforms the best published FFT for the CRAY Y/MP, network connections that can be switched in and out on demand, and a deposit model of message passing for parallelizing compilers.
