Coreinfo 3.31

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.

Installation

You run Coreinfo by typing "coreinfo”.

Using CoreInfo

For each resource it shows a map of the OS-visible processors
that correspond to the specified resources, with '*' representing the
applicable processors. For example, on a 4-core system, a line in the
cache output with a map of shared by cores 3 and 4.

Usage: coreinfo [-c][-f][-g][-l][-n][-s][-m][-v]

All options except -v are selected by default.
