Scalable Computing in the Multicore Era
Multicore architecture has become the trend of high performance processors. While it is generally accepted that we have entered the multicore era, concerns exist on scaling multicore processors. Technology is available, but major vendors are hesitant in entering the multicore market with processors that have large number of cores, citing Amdahls law.This is a very interesting phenomenon, where history seems to repeat itself on the scalability debate of parallel processing occurred 20 years ago. Following the scalable computing concept, especially the fixed-time and memory-bounded speedup metrics, in this study, we argue that the scalability of multicores is not limited by Amdahls law. We study two speedup models of multicore architecture from the scalable computing point of view. These two models show that multicores have a good scalability and add a new dimension of scalable computing.
