Hi Georgi, I think that the 50% is an average measure and that Gate uses only one core but at 100%. Because Gate is not actually able to split itself on two processors. If you want to use all your CPU power, you have to split your simulation in two peaces along the time and launch both at the same time. Cheers, Simon <div>2007/7/26, Georgi Gerganov <<a href="mailto:ggerganov@gmail.com">ggerganov@gmail.com</a>>:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hello everyone, I have installed Gate v3.1.1 on a Dual Core CPU Machine, but it seems that the simulations do not use all the CPU power. During a simulation both Cores are about 50% idle. Is there any way to make Gate use all the potential of the machine?
