General purpose CPUs with dozens of computing cores are currently reaching the market. Some researchers even expect chips with thousands of computing cores to be available in the foreseeable future. In this talk we will discuss the architectures of some current multi- and many-core CPUs with an emphasis on understanding the hardware foundation of today's parallel computing systems. In particular we will concentrate on the memory hierarchy of these CPUs and the inherent cost of sharing in cache-coherent multi-core systems. Additionally, we will examine typical problems that system designers and application programmers have to solve when they try to utilize such hardware architectures effectively.
