I'm not sure the best place to post this so I'm going general, feel free to move it if needed.

I've got an existing install of Ubuntu Server x64 12.04 running on a Dell Precision T7500 presently using 1 CPU (with 4 cores) and since I'm maxing out the CPU I am going to pick up the riser and add a second processor. Is there anything special I need to do with my install either prior to, or after the install to make sure it will see and utilize the additional processor?
