What do you do with the world's fastest, verified supercomputer?

What do you do with the world’s fastest, verified supercomputer? This week, Technology Now looks further into the world of supercomputers and explores what the world’s fastest, verified supercomputer, El Capitan, and its sister machine, Tuolumne, are used for. Rob Rieben, a computational physicist at Lawrence Livermore National Laboratory, tells us more.

This is Technology Now, a weekly show from Hewlett Packard Enterprise. Every week, hosts Michael Bird and Aubrey Lovell look at a story that's been making headlines, take a look at the technology behind it, and explain why it matters to organizations and what can be learnt from it.
