It's a calling a duck a duck issue. "Warehouse computing" looks a lot
like ethernet-connected HPC clusters, only larger. I can't afford to
waste a couple of days running Linpack, so my clusters don't appear on
the Top500. I do a mix of embarrassingly parallel jobs and
tightly-coupled parallel computations. It looks a lot like how the oil
& gas industry uses clusters.
