Dotnaught writes "A paper (PDF) to be presented later this month at the IEEE International Parallel and Distributed Processing Symposium in Atlanta describes a new approach to memory management that allows software applications to run up to 20% faster on multicore processors. Yan Solihin, associate professor of electrical and computer engineering at NCSU and co-author of the paper, says that using the technique is just a matter of linking to a library in a program that makes heavy use of memory allocation. The technique could be especially valuable for programs that are difficult to parallelize, such as word processors and Web browsers."
