World’s first exascale supercomputer is the world’s fastest

The first true exascale supercomputer, Frontier, is now the fastest in the world, toppling Fugaku, which held the title for the past two years, according to the latest TOPP500 list of the best performing supercomputers.An exascale computer is one that can perform 1018 (one quintillion) floating point operations per second (1 exaFLOPS), and Frontier, installed at Oak Ridge National Laboratory in Tennessee, weighed in at 1.12 exaFLOPS.

Use bash to change an IP address from dynamic to static on Linux

Changing the IP address of a Linux system from dynamic to static is not difficult, but requires a little care and a set of commands that you likely rarely use. This post provides a bash script that will run through the process, collect the needed information and then issue the commands required to make the changes while asking as little as possible from the person running it.The bulk of the script focusses on making sure that the correct settings are used. For example, it collects the 36-charater universally unique identifier (UUID) from the system so that you never have to type it in or copy and paste it into place.

Opening Up The Future “Venado” Grace-Hopper Supercomputer At Los Alamos

There are many interpretations of the word venado, which means deer or stag in Spanish, and this week it gets another one: A supercomputer based on future Nvidia CPU and GPU compute engines, and quite possibly if Los Alamos National Laboratory can convince Hewlett Packard Enterprise to support InfiniBand interconnects in its capability class “Shasta” Cray EX machines, Nvidia’s interconnect as well. …

Opening Up The Future “Venado” Grace-Hopper Supercomputer At Los Alamos was written by Timothy Prickett Morgan at The Next Platform.

Join me at PlatformCon 2022 to learn how to secure could-native applications using open source tools

PlatformCon 2022 is just around the corner and I’m excited to be speaking at the conference alongside other platform practitioners and pioneers. My talk, Using open-source software to secure cloud-native applications, will examine—you guessed it—how to use open-source software like Kubernetes to secure cloud-native applications.

I’m looking forward to giving this talk because I think this topic is extremely relevant to the Platform Engineering community. Cloud-native microservices applications bring so many amazing advantages for many software application needs, but they also bring lots of security challenges, and if those are handled incorrectly it can be a minefield. Ephemeral workloads appear and disappear, workload network addressing is transient, and traditional firewalls can’t police the data path effectively.

Open-source orchestration solutions like Kubernetes define an application-centric component called ‘NetworkPolicy,’ but they do not implement it. In my session I’ll discuss how, with a change of tools and mindset, open-source software can help to implement security for cloud-native applications whilst still allowing the user to benefit from all the advantages. I’m excited to help people understand how to get on the right path and give them enough information to make their own informed decision on how to proceed
