Hi, (please CC on replies, thanks) for the ganglia project (http://ganglia.sourceforge.net/) we are trying to find a heuristics to determine the number of physical CPU "cores" as opposed to virtual processors added by enabling HT. The method should work on 2.4 and 2.6 kernels.
So far it seems that looking at the "physical id", "core id" and "cpu cores" of /proc/cpuinfo is the way to go. In 2.6 I would try to find the distinct "physical id"s and and sum up the corresponding "cpu cores". The question is whether this would work for 2.4 based systems. Does anybody recall when the "physical id", "core id" and "cpu cores" were added to /proc/cpuinfo ?
