• Parallelizing Programs • Goal: speed up programs using multiple processors/cores 2 When is speedup important? • Applications can finish sooner – Search engines – High-res graphics – Weather prediction – Nuclear reactions – Bioinformatics Types of parallel machines • General purpose – GPU – Shared-memory multiprocessor (“multicore”) – Distributed-memory multicomputer • SIMD: single instruction,
Peer-to-peer (p2p) systems • Idea: create distributed systems out of individually owned, unreliable machines – Also different administrative domains – This has been tried with parallel computers in several projects, including “Grid Computing” • In p2p systems, the primary problem is lookup – given a data item stored at one or more places, find it

File Servers • Basic idea is simple – Clients open/read/write/close files indirectly, by going through servers, who access the disk – A client must be matched with a server – Clients do not store (permanent) files; servers do – Clients cache parts of (or whole) files Picture of File Server, Many Channels Basic Idea—Client Note:

Parallel Scientific Programming • Definitions – Speedup: Ts/Tp, where Ts is the sequential time and Tp is the time when using p cores • “Perfect speedup” is p, which really should be called “linear speedup” • Typically, speedup is less than p—but it can be larger because of memory hierarchy effects – Efficiency: Speedup/p •

Critical Sections: Implementing Logical Atomicity • Critical section of code is one that: – must be executed by one thread at a time • otherwise, there is a race condition – Example: linked list from before • Insert/Delete code forms a critical section • What about just the Insert or Delete code? – is that
