Bob,
>I no longer disable HT, I just make sure to use 1 thread per physical core and >let the O/S (Linux in my case) make certain that each physical thread runs on >its own physical core...

Can you elaborate a bit more?

Are you meaning you are setting affinity for crafty to use physical cores?

Just to go slightly off topic: Can the HT cores be used to manage cluster overheads?
Have you done any tests using HT for clusters?
