> When I took a tour of the Oak Ridge Leadership Computing Facility a few years ago, Buddy Bland, who is Project Director, told me he could tell when he comes to the Lab in the morning if they are running the LINPACK benchmark by looking at how much steam is coming out of the cooling towers.

Different programs consume dramatically different amounts of power.

That is true. But very few super computers track power consumption for different codes and do power aware scheduling. SuperMUC and IBM actually do a lot of research on this, because it is a rather new field in HPC.
