What is a logical processor aka LP?
A logical processor is what we call anything that shows up in Windows as a processor in task manager. More precisely it is the “number processors * number of cores * 2 if you are running Hyper Threading (HT) or now called Symmetric Multi Threading (SMT).” For example a dual proc quad core system with SMT enabled has 2 * 4 * 2 = 16 LP. A quad proc dual core system has 4 * 2 = 8 LP. Leading the 24LP effort was a blast and it is also why my blog has been pretty quiet recently.
