[Systeme] Computer where i could make simulations

Hello, I'm Paolo Parisen Toldin, phd student in visit. I'd like to know, is there some computer here that i could use to run a simulation ? I mean, something like at least a quad-core computer that will never turned off. My simulation probably will run for 5 days, more or less, (i have to calculate more or less 4^25 multiplications of matrix ) so i need something a bit powerful and be sure that no one is going to turning off. Do you have it?
