The new SPEC benchmark suite SPEC CPU2006 got released today. I've been involved in the development of the suite for the last couple of years - it's been a privilege to work with a bunch of talented people from other computer companies on this. Particular highlights were a couple of week long events (unfortunately in not-terribly-exotic places) were we spent the time enclosed in small rooms, surrounded by hot servers, figuring out why benchmark Z was giving us a hard time.
The benchmark suite is much bigger (in terms of lines of code, and required memory) than CPU2000. It contains much more C++ code, and some of this code pushes the language quite hard. So it has been very entertaining to work with such a large code base :)
