Arm creates virtual IoT chips to accelerate development

It can take years for a CPU to go from design to silicon, so Arm is helping developers get a jump on things by putting virtual models of its chip designs in the cloud. The virtual models will allow developers to write and test applications before the actual silicon ships.Dubbed Arm Total Solutions for IoT, the project is a full-stack solution intended for Internet of Things applications and use cases. Arm says the early access for developers, OEMs and service providers, as well as the reduction in product design cycles, could accelerate deployments by up to two years.Arm doesn’t make chips the way Intel and AMD do. It makes designs and licenses them to more than 800 OEMs, which are responsible for everything from embedded devices to servers. Once Arm releases the basic chip design to its partners, the partners then add their own IP to differentiate from the competition, which takes time.To read this article in full, please click here

Using the xargs command on Linux to simplify your work

The xargs command on Linux can make it easier to build and execute commands. If you want to run the same command for a group of files or users, xargs can often make that process easier. Here's a very simple example of xargs that creates or updates the update time on some files.$ echo file1 file2 file3 | xargs touch $ ls -l total 0 -rw-r--r--. 1 shs shs 0 Oct 15 12:41 file1 -rw-r--r--. 1 shs shs 0 Oct 15 12:41 file2 -rw-r--r--. 1 shs shs 0 Oct 15 12:41 file3 The command below is similar, but creates a file with blanks in its name because the -d specifies the input termination character.To read this article in full, please click here

Mid-band spectrum for 5G growing, with fits and starts

A new auction for enormously valuable mid-band spectrum and a rollback of availability for a different piece of it illustrates the uneven progress of 5G rollouts in the U.S. and represents a challenge for enterprises looking to take advantage of 5G technology. 5G resources What is 5G? Fast wireless technology for enterprises and phones How 5G frequency affects range and speed Private 5G can solve some problems that Wi-Fi can’t Private 5G keeps Whirlpool driverless vehicles rolling 5G can make for cost-effective private backhaul CBRS can bring private 5G to enterprises The mid-band is valuable because it’s in a “Goldilocks” zone of the wireless spectrum—its frequencies are high enough to support higher throughput, while also being low enough to propagate effectively across relatively large areas.To read this article in full, please click here

Windows Subsystem for Linux is ready for Windows 11

Microsoft has just made the Windows Subsystem for Linux (WSL) available in the Microsoft Store for Windows 11 systems. WSL is the application that allows Windows users to run a GNU/Linux environment directly on Windows without the overhead of a virtual machine or dual-boot setup.One good aspect is that it installs as a separate app, decoupled from the OS. This means that users can update the app without having to wait for Windows OS updates to become available.Summarizing your command-line usage on Linux The app in the Microsoft Store is not a new version of WSL. It’s still WSL 2, but is a preview version that was added as an option for end users to get the latest features faster and more conveniently. The binaries will no longer be part of the Windows image.To read this article in full, please click here

Marvell announces some very smart SmartNIC processors

Marvell has begun to sample the Octeon 10, a server microprocessor aimed at intelligent network management that has up to 24 Arm-compatible cores, making it as powerful as any server processor.Marvell refers to the Octeon processor line as data processing units (DPUs). They are designed to run high-throughput data in the cloud and on-premises. The DPU is more commonly called the SmartNIC because it can offload non-computational tasks from the CPU like network packet processing, data encryption and compression. That frees up CPU cores to run general-purpose applications.The Octeon 10 has a few firsts. It's the first processor made by TSMCs 5nm manufacturing process and the first processor to feature Arm’s Neoverse N2 core. The N2 core uses the new Armv9 architecture that the company claims can deliver 40% more single-threaded performance for a variety of workloads vs. the N1, but still retains the same level of power and area efficiency as N1.To read this article in full, please click here

The Dell/VMware relationship remains strong despite split

VMware is in the process of spinning out from Dell Technologies, but the working relationship remains as strong as ever with a bunch of announcements from VMworld.All told, the pair made four significant announcements at the show, the first being that VMware Cloud will be sold on systems acquired through Dell's Apex pay-as-you-go program.

Very quietly, Oracle ships new Exadata servers

You have to hand it to Larry Ellison, he is persistent. Or maybe he just doesn’t know when to give up. Either way, Oracle has shipped the latest in its Exadata server appliances, making some pronounced boosts in performance.Exadata was the old Sun Microsystems hardware Oracle inherited when it bought Sun in 2010. It has since discontinued Sun’s SPARC processor but soldiered on with servers running x86-based processors, all of them Intel despite AMD’s surging acceptance in the enterprise.When Oracle bought Sun in 2010, it was made clear they had no interest in low-end, mass market servers. In that regard, the Oracle Exadata X9M platforms deliver. The new Exadata X9M offerings, designed entirely around Oracle’s database software, include Oracle Exadata Database Machine X9M and Exadata [email protected] X9M, which Oracle says is the only platform that runs Oracle Autonomous Database in customer data centers.To read this article in full, please click here

Edge computing: The architecture of the future

As technology extends deeper into every aspect of business, the tip of the spear is often some device at the outer edge of the network, whether a connected industrial controller, a soil moisture sensor, a smartphone, or a security cam.This ballooning internet of things is already collecting petabytes of data, some of it processed for analysis and some of it immediately actionable. So an architectural problem arises: You don’t want to connect all those devices and stream all that data directly to some centralized cloud or company data center. The latency and data transfer costs are too high.That’s where edge computing comes in. It provides the “intermediating infrastructure and critical services between core datacenters and intelligent endpoints,” as the research firm IDC puts it. In other words, edge computing provides a vital layer of compute and storage physically close to IoT endpoints, so that control devices can respond with low latency – and edge analytics processing can reduce the amount of data that needs to be transferred to the core.To read this article in full, please click here

Intel: Under attack, fighting back on many fronts

At first glance, Intel doesn’t look like a company under siege. In its last fiscal year, it recorded $77.8 billion in sales and $20 billion in profit. Its market capitalization is $220 billion as of mid-September 2021.And yet it is. When you’re the leader, all your competition is gunning for you. Intel is wrestling with a loss of leadership in manufacturing and process nodes, it’s losing share to a very resurgent AMD, an unrelenting Nvidia is challenging Intel for AI dominance, the Atom processor failed spectacularly against Arm in the mobile market, and it’s on its third CEO in three years. More about Intel: A closer look at two newly announced Intel chips Intel shifts to a multiarchitecture model Intel revises its chip terminology and branding CEO Gelsinger shakes up Intel But Intel revels in the competition. “Our success in so many markets makes us targets for lots of companies,” said Lisa Spelman, corporate vice president and general manager of the Xeon and memory group. “So it’s not a surprise that we have competitors that want a piece of that.” To read this article in full, please click here
