In this episode we are looking at computers going fast. ‘Exascale’ means a computer is running a billion, billion operations every second.

At the 2024 ISC high-performance conference in Hamburg, Germany, the world’s second exascale machine was officially recognised: The Aurora supercomputer at Argonne National Laboratory officially broke the exascale barrier at 1.012 exaflops. So why does exascale matter, and why is it so difficult to achieve? Joining us to discuss is Susan Coghlan, Project Director of the Aurora exascale computer at the Argonne Leadership Computing Facility at Argonne National Laboratory in Lemont, Illinois.

In this episode we are taking a break from the norm to bring you a few of the amazing stories from the world of science and technology that haven’t quite made it into the podcast recently.

Our goal is to bring you a lot of amazing stories and important technological developments on this podcast, but the little stories in the middle where we take a break don’t always get the attention they deserve. So, this week, we’re bringing you some of the stories from around the world that haven’t quite made the podcast yet. And, of course, you’ll find details of all the stories we feature today in the show notes.

Don’t worry, this isn’t a regular thing - we’ll be back to normal next week.

This is Technology Now, a weekly show from Hewlett Packard Enterprise. Every week we 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 we can learn from it.

In this episode we are looking at why people are moving away from Virtual Private Networks, or VPNs, and are navigating towards Zero Trust Network Access, or ZTNAs.

VPNs have largely been unchallenged as the go-to cyber security option for organisations since they first came about in the mid-1990s. However, they do have security flaws which have been exploited by hackers and cyber criminals, leading many to ask whether there’s a more secure solution.

Joining us to discuss why ZTNA is becoming a more popular security option for organisations is Jaye Tillson, HPE’s Director of Strategy in Cyber Security.
