The Case of the Missing Supercomputer Performance: Achieving Optimal Performance on the 8,192 Processors of ASCI Q
TL;DR: This paper describes how to improved the effective performance of ASCI Q, the world's second-fastest supercomputer, to meet expectations and provides insight into performance analysis that is immediately applicable to other large-scale supercomputers.
Proceedings ArticleDOI
High Performance Messaging on Workstations: Illinois Fast Messages (FM) for Myrinet
TL;DR: The FM messaging primitives and the critical design issues in building a low-latency messaging layers for workstation clusters are described and detailed measurements show how each of these features contribute to high performance.
Proceedings ArticleDOI
Entering the petaflop era: the architecture and performance of Roadrunner
Kevin J. Barker,Kei Davis,Adolfy Hoisie,Darren J. Kerbyson,Michael Lang,Scott Pakin,José Carlos Sancho +6 more
TL;DR: A detailed architectural description of Roadrunner and a detailed performance analysis of the system are presented and a case study of optimizing the MPI-based application Sweep3D to exploit Roadrunner's hybrid architecture is also included.
Journal ArticleDOI
Fast messages: efficient, portable communication for workstation clusters and MPPs
TL;DR: Implementations on a Cray T3D and a Myrinet-based workstation cluster demonstrate that FM can deliver much of the underlying hardware's performance to both higher-level messaging layers and applications.
