Coreinfo v3.21

Coreinfo is a useful tool from Sysinternals that displays 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 is a command line tool so you should be familiar with working with such tools before you try to use it.

It was developed by Mark Russinovich for Sysinternals (now part of Microsoft). It uses the GetLogicalProcessorInformation function in the Windows operating system to obtain the info and print it.
