It is:
detected        Intel(R) Xeon(R) CPU E5-4650 0 @ 2.70GHz
but the timing is kinda misleading because there are 4 of these cpu's in the system. When the threads can be spread out over multiple cpus then there isn't as much of a memory bandwidth bottleneck. If I force it to use one node (8 cores) with numactl then I get 11.8 seconds.
