xeon x5500

[stll]

Hi There,

I am using a xeon x5500 6.67GHz quad core processor for simulation.
When run my program, I noticed that the CPU is occupied 25% only, and the usage of the 4 cores looks the same (all at about 25% level usage).

May I know if anybody experienced that and what should I do to use the max power of the processor, or even one core. I did several test and it looks that this processor (benchmark score ~3000) runs my program about 3 times faster than my old pentium duo core (benchmark score ~300). I think it should/could be faster.

Thank you very much for your help!
