I suspect it might be because you have a CPU which supports HyperThreading (HT). If this is the case then there is nothing to worry about. My understanding (correct me if I am wrong), is that HT essentially makes you computer think there are two CPUs (look in your System properties). If you are just seeing 50% usage then it just means that Stata does not support HT and so does not have any performance boost as a result of this.

If you disable HT (which you can typically do in the BIOS) then I would expect that CPU usage would shoot up to 100%. However, the actual performance which you get will be the same.

Hello all,

I was puzzled by one annoying thing of my computer and I don't know whether I should fault Stata or my computer.

Basically, I am running computational intensive Monte Carlo simulations on Stata under Windows XP on a brand new Dell Inspiration laptop. Somehow my Task Manager shows that the computer is using 50% of its CPU usage on this computer. It is weird because the same program always use 100% of the CPU on my old machine.

I suspect it is the problem of my computer rather than my Stata, though I am not 100% sure. Anyone has any ideas to release the remaining 50% CPU power of my computer? I really appreciate your help!
