Roadrunner Architectural Presentations

• Roadrunner and Hybrid Computing (8/22/2007)

  This presentation by Ken Koch, Roadrunner Technical Manager, for the Weapons Science and Engineering Capability Review, covers Roadrunner goals and thrusts, an explanation of hybrid computing and the Cell processor, Roadrunner system and Cell-acceleration architecture, an overview of programming concepts, and an overview of algorithms and applications.

• Roadrunner Summary (3/12/2007)

  Roadrunner is outlined in this very brief set of slides.  The presentation covers the microprocessor and system trends leading to a Roadrunner hybrid architecture, the goals and timeline for the Roadrunner supercomputer at LANL, the Cell chip roadmap and some specifics of the actual Roadrunner architecture and configuration, and tools and issues for programming the machine as a hybrid architecture.LA-UR-07-1687  Presenter: Kenneth Koch, CCS Div., LANL

• Roadrunner Presentation at SC06 (11/14-17/2006)

  This talk covers the goals for the  Roadrunner supercomputer at LANL, the details of the actual machine architecture, plans and issues for programming the machine as a hybrid architecture., and plans and experiences to date for algorithms and applications of interest to LANL.  The talk is targeted to introduce prospective Hybrid Alliance Program partners to the Roadrunner architecture and the timelines for the system.  The talk also covers some of the hybrid programming issues and outlines LANL’s plans and experiences in looking at algorithms and applications running on the accelerated Roadrunner system.LA-UR-06-8276 Presenter: Kenneth Koch, CCS Div., LANL

• Roadrunner Talk at UT Cell Workshop (10/25-26/06)

  Roadrunner is described and hybrid programming issues are covered in this talk.  Roadrunner will be deployed in multiple phases.  This talk introduces the actual machine architecture from the current Base System now being delivered through the final Cell-accelerated system in early 2008.  There will be an emphasis on the hardware and software of the Cell-accelerated final system configuration.  The talk also discusses how one might plan to program this hybrid/heterogeneous architecture of Roadrunner  and how that will be more complicated than simply programming a single Cell processor.

• LACSI 2006 Heterogeneity Panel (10/18/2006)

  Some unique aspects of heterogeneous computing are highlighted in this short talk for the Los Alamos Computer Science Institute (LACSI) panel on Heterogeneous Computing.  Various forms of heterogeneous computer developments and trends  are presented followed by a depiction of the Roadrunner Final Cell-Accelerated System heterogeneous-hybrid architecture.  Similarities and differences in programming these heterogeneous systems compared to conventional computer systems are highlighted.  The talk wraps up by acknowledging that heterogeneous supercomputers have existed in the past and that many of the programming techniques of the past can be leveraged to help with programming concepts needed for modern heterogeneous computer systems.
