Dongarra is one of the authors of the Linpack computing benchmark, introduced way back in 1979. With this benchmark, supercomputing sites can rate computers' relative performance at solving a set of linear equations.
Dongarra's group has ported Linpack to the iPad 2 to see how fast it really is, accordi
