All in all, Intel claims a 2x to 3x improvement in AI workloads, a 2.8x boost in memory throughput, and a 2.9x improvement in the DeepMD+LAMMPS AI inference workload.To read this article in full, please click here

Getting started on the Linux (or Unix) command line, Part 1

To get started as a Linux (or Unix) user, you need to have a good perspective on how Linux works and a handle on some of the most basic commands. This first post in a “getting started” series examines some of the first commands you need to be ready to use.On logging in When you first log into a Linux system and open a terminal window or log into a Linux system from another system using a tool like PuTTY, you’ll find yourself sitting in your home directory. Some of the commands you will probably want to try first will include these:pwd -- shows you where you are in the file system right now (stands for “present working directory”) whoami – confirms the account you just logged into date -- show the current date and time hostname -- display the system’s name Using the whoami command immediately after logging in might generate a “duh!” response since you just entered your assigned username and password. But, once you find yourself using more than one account, it’s always helpful to know a command that will remind you which you’re using at the moment.To read this article in full, Continue reading

LiquidStack expands into single-phase liquid cooling

LiquidStack, one of the first major players in the immersion cooling business, has entered the single-phase liquid cooling market with an expansion of its DataTank product portfolio.Immersion cooling is the process of dunking the motherboard in a nonconductive liquid to cool it. It's primarily centered around the CPU but, in this case, involves the entire motherboard, including the memory and other chips.Immersion cooling has been around for a while but has been something of a fringe technology. With server technology growing hotter and denser, immersion has begun to creep into the mainstream.To read this article in full, please click here

Aurora enters TOP500 supercomputer ranking at No. 2 with a challenge for reigning champ Frontier

Frontier maintained its top spot in the latest edition of the TOP500 for the fourth consecutive time and is still the only exascale machine on the list of the world's most powerful supercomputers. Newcomer Aurora debuted at No. 2 in the ranking, and it’s expected to surpass Frontier once the system is fully built.Frontier, housed at the Oak Ridge National Laboratory (ORNL) in Tenn., landed the top spot with an HPL score of 1.194 quintillion floating point operations per second (FLOPS), which is the same score from earlier this year. A quintillion is 1018 or one exaFLOPS (EFLOPS). The speed measurement used in evaluating the computers is the High Performance Linpack (HPL) benchmark, which measures how well systems solve a dense system of linear equations.To read this article in full, please click here

How to determine RTOs and RPOs for backup and recovery

When evaluating the design of your backup systems or developing a design of a new backup and recovery system, there are arguably only two metrics that matter: how fast you can recover, and how much data you will lose when you recover. If you build your design around the agreed-upon numbers for these two metrics, and then repeatedly test that you are able to meet those metrics in a recovery, you’ll be in good shape.The problem is that few people know what these metrics are for their organization. This isn’t a matter of ignorance, though. They don’t know what they are because no one ever created the metrics in the first place. And if you don’t have agreed upon metrics (also known as service levels), every recovery will be a failure because it will be judged against the unrealistic metrics in everyone’s heads. With the exception of those who are intimately familiar with the backup and disaster recovery system, most people have no idea how long recoveries actually take.To read this article in full, please click here

UK to house three new supercomputers by 2025

How to calculate factorials in Linux

In this video transcript, Sandra Henry-Stocker discusses how to calculate factorials on a Linux system. She explains that factorials are the multiplication of numbers starting with a specified number and decreasing incrementally until reaching 1. To calculate factorials on Linux, you can use commands like "seq" and "bc." The "seq" command is used to generate a list of sequential numbers, and the "bc" command is used to perform the factorial calculations.

Using the Linux compgen bash builtin

Linux’s compgen command is not actually a Linux command. In other words, it’s not implemented as an executable file, but is instead a bash builtin. That means that it’s part of the bash executable. So, if you were to type “which compgen”, your shell would run through all of the locations included in your $PATH variable, but it just wouldn’t find it.$ which compgen /usr/bin/which: no compgen in (.:/home/shs/.local/bin:/home/shs/bin:/usr/local/bin: /usr/bin:/usr/local/sbin:/usr/sbin) Obviously, the which command had no luck in finding it.If, on the other hand, you type “man compgen”, you’ll end up looking at the man page for the bash shell. From that man page, you can scroll down to this explanation if you’re patient enough to look for it.To read this article in full, please click here

Cisco and Aviz coordinate support for enterprise SONiC networks

Cisco is teaming with Aviz Networks to offer an enterprise-grade SONiC offering for large customers interested in deploying the open-source network operating system.Under the partnership, Cisco’s 8000 series routers will be available with Aviz Networks’ SONiC management software and 24/7 support. The support aspect of the agreement may be the most significant portion of the partnership, as both companies attempt to assuage customers’ anxiety about supporting an open-source NOS.While SONiC (Software for Open Networking in the Cloud) is starting to attract the attention of some large enterprises, deployments today are still mainly seen in the largest hyperscalers. With this announcement, Cisco and Aviz are making SONiC more viable for smaller cloud providers, service providers, and those very large enterprises that own and operate their own data centers, said Kevin Wollenweber, senior vice president and general manager with Cisco networking, data center and provider connectivity.To read this article in full, please click here

Security startup Airgap Networks brings telco technologies to the LAN

AI-generating malware, deep fake identity spoofing, and state-sponsored ransomware are just a few of the latest methods that attackers are using to bypass traditional cybersecurity tools. Ritesh Agrawal, CEO of cybersecurity startup Airgap Networks, noticed that many of the attacks that compromise enterprise networks fail to penetrate telco and service provider networks.“Even though they’re deploying the same routers, switches, and firewalls, there’s something fundamentally different about telco networks that shields them from many threats to enterprise LANs,” Argawal said. Agrawal has 20 years of experience with cybersecurity, enterprise networking, and cloud computing, most of that time spent with Juniper Networks focusing on telco and large enterprise clients.To read this article in full, please click here
