Dualcore processors are already ubiquitous, quadcore processors will spread out this year, systems with a larger number of cores exist, and more are planned. Some cores even execute multiple threads. Are these processors just SMP systems on a chip? Is OpenMP ready to be used for these architectures? We take a look at the cache and memory architecture of some popular modern processors using kernel programs and some application codes which have been developed for large shared memory machines beforehand.
