Feature: 'Debugging Concurrency'

In today's second feature article, Philippe Paquet, the Core Technology Manager for Driv3r and Stuntman creator Reflections, discusses the tricky and increasingly important issue of debugging code on multi-core processors. Paquet comments in his introduction to the piece: "In July 2000 Apple brought dual-processing to its PowerMac line and symmetric multiprocessing (SMP) became officially mainstream. Less than 4 years later, Intel introduced a feature called "Hyperthreading" to their IA-32 processor line and simultaneous multithreading (SMT) became mainstream too. Before the end of the year, we will see Intel, AMD and Microsoft introducing multi-core processors to the masses. Multithreaded applications are now a fact of life and probably the only way toward maximum performance. Unfortunately, with multithreaded applications come a new class of bugs which challenge even the most experienced programmers."
