You've seen the Raspberry Pi CM4 in a mini-ITX case. Now here's four in a mini-ITX case

How to coordinate 16 Arms

Keen on Kubernetes? It has been a long wait, but the Turing Pi 2 is finally close to shipping.

A year and a bit after the Raspberry Pi Compute Module 4 shipped, and one of our crafty commenters noticed that a new version was coming, the Turing Pi 2 board is close enough to shipping that zealous Pi-related YouTuber Jeff Geerling has got his hands on one.

Unlike the Alftel Seaberry we covered last month, this is not a Pi CM4 in a mini-ITX case. No, it's four Pi CM4s in a mini-ITX case. No need to imagine a Beowulf cluster of these: it's specifically designed to build such a thing, or more contemporaneously, a Kubernetes cluster of them.

Turing Pi 2

Turing Pi 2

The Turing 2 is the successor to the Turing 1, which let you cluster up to seven Pi 1, Pi 3 or Pi 3+ Compute Modules. The snag was that even the CM3+ was a bit feeble, with only a gig of RAM and four 1.2 MHz Cortex-A53 cores. Even seven of them wouldn't form a very powerful cluster. Although it holds fewer boards, the Turing 2 is significantly beefier, with two Mini-PCIe slots, two SATA III ports, 12Gbps of interconnect bandwidth and a managed switch to manage intra-cluster communications.

A less apparent advantage over the Turing Pi 1 is greater choice of boards. While the older Pi Compute Modules presented an SoDIMM-style edge connector, the CM4 needs a carrier board. But that means that a number of devices with compatible connectors are available, so that the Turing Pi 2 isn't limited to Pi Compute Modules. You can also use the Nvidia Jetson Nano, Pine64 SOQuartz, or Radxa ROCK3 Computing Module.

This isn't a desktop computer, and although you could certainly use it as one, it would be a waste of the device's potential. But it will make a fine inexpensive local K8s cluster, or as the manufacturers suggested back when it was announced, for prototyping workloads to deploy onto Amazon's ARM-powered AWS Graviton service.

You could be forgiven for forgetting, but there's more to life than Linux, of course. There are an assortment of other OSes for the Pi hardware, and with a little adaption, some would be ideal for this. There's a preliminary but usable port of the newly independent (from Nokia's Bell Labs) Plan 9 for the Pi 4. The successor to Plan 9, Inferno, is also cluster-capable, and there's an existing, lavishly documented RasPi port of that too. Some assembly required, though.

Looking for an idea for a radical tech startup? Port Google's Gvisor onto Plan 9's APE to make a super-lightweight K8s killer. Your correspondent just asks for a 1 per cent cut. ®

  • Lonestar plans to put datacenters in the Moon's lava tubes
    How? Founder tells The Register 'Robots… lots of robots'

    Imagine a future where racks of computer servers hum quietly in darkness below the surface of the Moon.

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality. Lonestar Data Holdings has a unique mission unlike any other cloud provider: to build datacenters on the Moon backing up the world's data.

    "It's inconceivable to me that we are keeping our most precious assets, our knowledge and our data, on Earth, where we're setting off bombs and burning things," Christopher Stott, founder and CEO of Lonestar, told The Register. "We need to put our assets in place off our planet, where we can keep it safe."

  • Conti: Russian-backed rulers of Costa Rican hacktocracy?
    Also, Chinese IT admin jailed for deleting database, and the NSA promises no more backdoors

    In brief The notorious Russian-aligned Conti ransomware gang has upped the ante in its attack against Costa Rica, threatening to overthrow the government if it doesn't pay a $20 million ransom. 

    Costa Rican president Rodrigo Chaves said that the country is effectively at war with the gang, who in April infiltrated the government's computer systems, gaining a foothold in 27 agencies at various government levels. The US State Department has offered a $15 million reward leading to the capture of Conti's leaders, who it said have made more than $150 million from 1,000+ victims.

    Conti claimed this week that it has insiders in the Costa Rican government, the AP reported, warning that "We are determined to overthrow the government by means of a cyber attack, we have already shown you all the strength and power, you have introduced an emergency."

  • China-linked Twisted Panda caught spying on Russian defense R&D
    Because Beijing isn't above covert ops to accomplish its five-year goals

    Chinese cyberspies targeted two Russian defense institutes and possibly another research facility in Belarus, according to Check Point Research.

    The new campaign, dubbed Twisted Panda, is part of a larger, state-sponsored espionage operation that has been ongoing for several months, if not nearly a year, according to the security shop.

    In a technical analysis, the researchers detail the various malicious stages and payloads of the campaign that used sanctions-related phishing emails to attack Russian entities, which are part of the state-owned defense conglomerate Rostec Corporation.

    Trade watchdog, and President, reminds that COPPA can ban ya

    The US Federal Trade Commission on Thursday said it intends to take action against educational technology companies that unlawfully collect data from children using online educational services.

    In a policy statement, the agency said, "Children should not have to needlessly hand over their data and forfeit their privacy in order to do their schoolwork or participate in remote learning, especially given the wide and increasing adoption of ed tech tools."

    The agency says it will scrutinize educational service providers to ensure that they are meeting their legal obligations under COPPA, the Children's Online Privacy Protection Act.

  • Mysterious firm seeks to buy majority stake in Arm China
    Chinese joint venture's ousted CEO tries to hang on - who will get control?

    The saga surrounding Arm's joint venture in China just took another intriguing turn: a mysterious firm named Lotcap Group claims it has signed a letter of intent to buy a 51 percent stake in Arm China from existing investors in the country.

    In a Chinese-language press release posted Wednesday, Lotcap said it has formed a subsidiary, Lotcap Fund, to buy a majority stake in the joint venture. However, reporting by one newspaper suggested that the investment firm still needs the approval of one significant investor to gain 51 percent control of Arm China.

    The development comes a couple of weeks after Arm China said that its former CEO, Allen Wu, was refusing once again to step down from his position, despite the company's board voting in late April to replace Wu with two co-chief executives. SoftBank Group, which owns 49 percent of the Chinese venture, has been trying to unentangle Arm China from Wu as the Japanese tech investment giant plans for an initial public offering of the British parent company.

  • SmartNICs power the cloud, are enterprise datacenters next?
    High pricing, lack of software make smartNICs a tough sell, despite offload potential

    SmartNICs have the potential to accelerate enterprise workloads, but don't expect to see them bring hyperscale-class efficiency to most datacenters anytime soon, ZK Research's Zeus Kerravala told The Register.

    SmartNICs are widely deployed in cloud and hyperscale datacenters as a means to offload input/output (I/O) intensive network, security, and storage operations from the CPU, freeing it up to run revenue generating tenant workloads. Some more advanced chips even offload the hypervisor to further separate the infrastructure management layer from the rest of the server.

    Despite relative success in the cloud and a flurry of innovation from the still-limited vendor SmartNIC ecosystem, including Mellanox (Nvidia), Intel, Marvell, and Xilinx (AMD), Kerravala argues that the use cases for enterprise datacenters are unlikely to resemble those of the major hyperscalers, at least in the near term.
