The International Supercomputer Conference (ISC) kicked off in Hamburg, Germany this week with the release of the TOPP500 list of the fastest supercomputers, with a computer named Frontier taking first place.Deployed at the US Department of Energy’s Oak Ridge National Labs, it is the first exascale machine (1018 floating point operations per second)—an HPE-Cray EX system powered by AMD Epyc CPUs and Instinct MI250 GPUs.Intel had hoped to win the exascale battle with an other DoE computer called Aurora, but AMD beat it to the punch. Frontier also beat out competitors from China and Japan that had hoped to win the exascale race.To read this article in full, please click here
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.Frontier also captured the title of most energy efficient supercomputer, generating 62.68 GFLOP per watt.Frontier’s speed bumps down Fugaku at the RIKEN Center for Computational Science (R-CCS) in Kobe, Japan, from number 1 on the TOPP500 list last fall to number 2 now. Fugaku scored 442 peta FLOPS (PFLOPS) on 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

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.

Malware targeting Linux environments has increased massively in the past year, with threat actors using a variety of techniques to carry out operations.
When you think of data-center networking, you almost certainly think of Ethernet switches. These gadgets have been the foundation of the data-center network for decades, and there are still more Ethernet switches sold into data-center applications than any other technology. Network planners, though, are starting to see changes in applications, and those changes are suggesting that it’s time to think a bit harder about data center network options. Your data center is changing, and so should its network.To read this article in full, please click here
It's quite easy to get bash to concatenate strings and do simple math on Linux, but there are a number of options for you to use. This post focusses on concatenating strings, but also shows how one of the operators (+=) also plays a primary role in incrementing numbers.Concatenating strings
In general, the only time that you'd want to concatenate strings on Linux is when one string is already defined and you want to add more to it. For example, if you have a script that greets the person running it, you might set up a string in the script to prepare the greeting and then add the person's username or name before displaying it.

Semiconductor manufacturer and infrastructure software giant Broadcom will acquire virtualization and enterprise cloud vendor VMware in a deal worth roughly $61 billion in stock and cash, the companies announced on Thursday. Broadcom will also assume $8 billion of VMware net debt as part of the deal.The deal, which is still subject to customary regulatory approval and closing conditions, will see the existing Broadcom Software Group fully rebranded as VMware.The deal is the latest in Broadcom's years-long pattern of high-profile acquisitions. The company acquired network switching vendor Brocade in 2016 for almost $6 billion, development and security software firm CA Technologies in 2018 for $19 billion, and security firm Symantec's enterprise security business in 2019 for over $10 billion.To read this article in full, please click here
A VLAN is a logical subnetwork of devices in a broadcast domain that is partitioned by network switches and/or network management software to act as its own distinct LAN. Switches that support VLANs give network managers the ability to create flexible virtual network segments that are independent of the underlying physical wired or wireless topology.VLANs operate at either Layer 2 (data-link layer) or Layer 3 (network layer), depending on the design of the network. Several different network protocols support VLANs, most notably Ethernet and Wi-Fi.To read this article in full, please click here
Nvidia unveiled high-performance computing (HPC) reference designs and new water-cooling technology for its GPUs at the annual Computex tradeshow in Taipei, Taiwan.The reference designs employ Nvidia's forthcoming Grace CPU and Grace Hopper Superchips, due next year. Grace is an Arm-based CPU – Nvidia’s first for the server market. Hopper is Nvidia’s next generation of GPU processors.

If chipmaker Broadcom buys virtualization and multi-cloud vendor VMware as rumored, enterprise customers should watch out for whether the deal hampers the software vendor’s innovation, experts say.Others say the purchase—valued to be about $60 billion by the The Wall Street Journal—could be a boon for Broadcom by moving forward its years-long efforts to acquire enterprise technology.To read this article in full, please click here
IBM has added a new member to its Spectrum Scale Enterprise Storage Server (ESS) portfolio that featuers a faster controller CPU and more throughput and that is designed to work with Nvidia’s DGX dense compute servers for AI training.The new ESS 3500 is a 2U design with 24 drive bays and a maximum raw capacity of 368TB. But it can achieve up to 1PB through LZ4 compression, a first for the series that earlier ESS versions do not have. The ESS 3500 can achieve up to 91GB/s of throughput performance, better than the 80GB/s of the older models.To read this article in full, please click here

Pure Storage and data-warehouse developer Snowflake have partnered to bring Snowflake’s cloud-based data-warehousing technology on-premises.Under the new relationship, the Snowflake Data Cloud compute engine will be run on Pure Storage’s FlashBlade file- and object-storage array. Pure has another line of storage devices, called FlashArray, but those serve a different purpose, notes Rob Lee, CTO of Pure Storage.“I look at FlashArray as our scale-up platform, and FlashBlade as our scale out platform,” he said. “We tend to see FlashArray applied much more to transactional database-type workloads, like OLTP, trading databases, billing databases, where you have high update rates, and we tend to see FlashBlade applied to data warehouses or analytics types of environments where you don't have a ton of transactional change, but you've got a lot of analysis, a lot of read-type workloads,” he said.To read this article in full, please click here
There are many ways to extract substrings from lines of text using Linux and doing so can be extremely useful when preparing scripts that may be used to process large amounts of data. This post describes ways you can take advantage of the commands that make extracting substrings easy.Using bash parameter expansion
When using bash parameter expansion, you can specify the starting and ending positions for the text that you want to extract. For example, you can create a variable by assigning it a value and then use syntax like that shown below to select a portion of it.To read this article in full, please click here
In this Linux tip, learn how to use the strace and ltrace commands. They provide information on the system and library calls that a Linux process makes and this information can help when you're troubleshooting a process that's not behaving as you'd expect.
Private clouds make efficient use of storage, compute, and memory resources, can provide faster response times for enterprise applications, and help comply with regulations about where data is stored.What is a private cloud?
The concept of a private cloud is relatively simple and straightforward. NIST defined it in its NIST Cloud Computing Standards Roadmap back in 2013 with this description: “The private cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units).”To read this article in full, please click here
