Roadmap • Threads: Resource ownership and execution • Symmetric multiprocessing (SMP). • Microkernel • Case Studies of threads and SMP: – Windows – Solaris – Linux
Traditional View • Traditionally, the computer has been viewed as a sequential machine. – A processor executes instructions one at a time in sequence – Each instruction is a sequence of operations • Two popular approaches to providing parallelism – Symmetric MultiProcessors (SMPs) – Clusters (ch 16)
