Using CoreInfoįor each resource it shows a map of the OS-visible processors InstallationĮxtract the archive to a directory and then run Coreinfo by typing from that directory Coreinfo in the console on a 32 bit Windows version or Coreinfo64 for a 64 bit version. Coreinfo is useful for gaining insight into the processor and cache topology of your system. 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 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.
