From a New York Times story by Cade Metz headlined “Turing Award Won by Programmer Who Paved Way for Supercomputers”:

In the late 1970s, as a young researcher at Argonne National Laboratory outside Chicago, Jack Dongarra helped write computer code called Linpack.

Linpack offered a way to run complex mathematics on what we now call supercomputers. It became a vital tool for scientific labs as they stretched the boundaries of what a computer could do. That included predicting weather patterns, modeling economies and simulating nuclear explosions.
