ANL/MCS Seminar Announcement
"Past Predications, the Present, and Future Trends in HPC Microarchitectures"

DATE: March 7, 2007
TIME: 10:00 am
SPEAKER: Peter M. Kogge, Associate Dean for Research, University of Notre Dame
LOCATION: Building 221 Conference Room A216, Argonne
HOST: Bill Gropp

Description:
When we look at the prehistory for microarchitectures and execution models for HPC computers we see two trends, increasing intra-CPU instruction-level parallelism and various incantations of multiple CPU systems, most recently in the multi-core arena. This led to the articulation of the "memory wall" and power as two fundamental roadblocks, and a recent surge in memory system techniques that attack one aspect of the wall - namely bandwidth.

In this talk I will use the ITRS roadmap to explore exactly what this means as we extrapolate current "killer micro" architectures, with a focus on some surprising conclusions. I will also explore the potential of two alternative evolutionary possibilities: the rapidly maturing development of explicit multi-threading as a baseline, and a more speculative, but perhaps more interesting, possibility where it is the computation, and not the data, that may move around the system.
