What Do They Run on America's Fastest SuperComputer?

In July I paid a visit to Lawrence Livermore National Labs which hosts the fastest supercomputer in the US, a couple of months earlier it was the fastest supercomputer in the world, but Moore's law means computer supremacy is fleeting. El Capitan is an exaflop scale system, meaning is can run 10^18 calculations per second (a billion, billion), and this is measured by benchmarks that require tight cooperation between it's thousands of cores. There are datacenters with many more processors, but t
