I'm not sure I'm quite following. I tried making the changes you
suggested, but it still looks the same. Linux still identifies it as a
single socket with two cores. I've rechecked the performance and it
still looks like a single socket with two cores (measuring memory
latencies and bandwidth). Any other ideas?
