Note that it's probably a bad idea to do this; I've resorted to this evil because of suspicion about CPU being defective or physically damaged.

./cpu_topology.sh - lists what virtual cores correspond to the same physical core
You need to adjust other scripts according to ./cpu_topology.sh results, they are given for typical 4 cores with HT case
