Coreinfo show the useful dump information regarding your physical processor, 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.

Usage: coreinfo [-c][-g][-l][-m][-n][-s]
-c Dump information on cores.
-g Dump information on groups.
-l Dump information on caches.
-m Dump NUMA access cost.
-n Dump information on NUMA nodes.
-s Dump information on sockets.

Coreinfo Output:
The following output is from an 2-socket, quad-core system, AMD Opteron system. Note how each socket corresponds to a NUMA node, and each CPU has its own L1 instruction and data cache and L2 unified cache.
