Parallel Performance: Optimize Managed Code For Multi-Core Machines
Multi-processor machines are now becoming standard while the speed increases of single processors have slowed down. The key to performance improvements is therefore to run a program on multiple processors in parallel. Unfortunately, it is still very hard to write algorithms that actually take advantage of those multiple processors. In fact, most applications use just a single core and see no speed improvements when run on a multi-core machine. We need to write our programs in a new way.
