Title:
Talk 1--Adapting Codes for a Heterogeneous Multi-core Red Storm Speaker:
Talk 1--Doug Doerfler, 1422 Date/Time: Monday, October, 20, 2008, 3:00 PM Location: CSRI Building , Room 90 (Sandia NM) Brief Abstract: Talk 1--Sandia and Cray have recently upgraded a large fraction of Red Storm's compute partition to quad-core processors, while the rest remains dual-core. The quad-core processors differ from the dual-core in clock rate, memory specifications, and FLOPS per clock. This presentation will show our experience with running applications on both processor types and will discuss what we have done to HPL on the whole machine in a manner that tries to use the processors in the most efficient manner. Brief Abstract: Talk 2--Future generations of scalable computers will rely on multicore nodes for a significant portion of overall system performance. Presently most applications and libraries cannot exploit multiple cores beyond running addition MPI processes per node. In this talk we discuss important multicore architecture issues, programming models, algorithms requirements and software design related to effective use of scalable multicore computers. In particular, we focus on important issues for library research and development, making recommendations for how to effectively develop libraries for future scalable computer systems.
