LANS Informal Seminar
"Is there an easy route to reach the peak of performance?"
DATE: July 14, 2011
TIME: 15:00:00 - 16:00:00 Description:
SPEAKER: Jesse Wang, Chicago State University
LOCATION: Bldg 240 Conference Center 1416, Argonne National Laboratory
The gap between modern computer architectures and software performance speed rate has been ever increasing rapidly. The reason being is that compilers often cannot generate efficient object codes. In this presentation, we will re-visit Jim Cody's (Argonne Scientist) concepts of subroutine library functions. And a LMG(lean, mean, and green) algorithm that can produce loop-less computer codes to reach peak performance on any targeted computer systems for any well-defined computational tasks will be presented. The algorithm can be applied to produce codes for several kernel functions to improve the performance of some DOE scientific application packages. Some performance results will be shown.
TIME: 15:00:00 - 16:00:00
