Re: That's multiprocessing, not multithreading
True, make -j 32 on our 64-core Opteron machine does absolutely fly through big builds, but that is indeed multi-processing rather than multi-threading proper. We do write code that scales well up to 64 threads (up to 50x speed-up), but that only really works if you have serious compute loads (like multi Gpixel images) to process. Many applications don't use multiple threads very heavily.
