Tools for System Internals

While googling on some SQL Server internals, I found a site which has lots of tools to get vital information about your system. I've used some of them and they are very useful.  


One of such tools is "Coreinfo.exe".
"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’ GetLogicalProcessorInformationfunction 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. "
