A mechanistic performance model for superscalar out-of-order processors
Stijn Eyerman, Lieven Eeckhout, Tejas Karkhanis, James E. Smith
Article No.: 3
DOI: 10.1145/1534909.1534910

A mechanistic model for out-of-order superscalar processors is developed and then applied to the study of microarchitecture resource scaling. The model divides execution time into intervals separated by disruptive miss events such as branch...

Practical and low-overhead masking of failures of TCP-based servers
Dmitrii Zagorodnov, Keith Marzullo, Lorenzo Alvisi, Thomas C. Bressoud
Article No.: 4
DOI: 10.1145/1534909.1534911

This article describes an architecture that allows a replicated service to survive crashes without breaking its TCP connections. Our approach does not require modifications to the TCP protocol, to the operating system on the server, or to any of...
