I'm looking for a way to have a precise architecture information about Xeon E5420. This processor have 4 cores and 2x6Mo cache, so 2 cores shares a 6Mo cache.
I'm working on machines that have 2 processors xeon, thus have 8 cores, and looking at /proc/cpuinfo just gives me indication about which core is on which processor.
Usually odd cores are on a processor and even cores are on the other but I didn't find a way to know which two cores on the same processor shares the 6Mo cache.
Any clue?
