This document appears to be slides from a lecture on advanced operating systems given in the fall of 2012. It discusses computational biology, physics simulations, limitations of wire communications speeds and heat dissipation, examples of high-performance computer systems, shared memory architectures, message passing between processes, cache hit rates, and directory-based cache coherence. The document is attributed to Van Hoang Nguyen from the Department of Computer Science at HUA.
