Coreinfo

Coreinfo is a command-line utility that shows you the mapping between logical processors and the physical processor, NUMA node, and socket on which they reside, as well as the cache s assigned to each logical processor. It uses the Windows  GetLogicalProcessorInformation function to obtain this information and prints it to the screen, representing a mapping to a logical processor with an asterisk e.g. ?* . Coreinfo is useful for gaining insight into the processor and cache topology of your system.
