New to cuda

Hi I just installed cuda 5.0 on my box with two tesla 2050’s

while compiling the samples I logged started a new ssh session
and was wanting to try checking the stats… using nvidia-smi -l

nothing ever shows for utilization or processes … my questions are …
When making the samples shouldn’t the utilization and mem usage move from 0?
