Turing Pi 2 crowdfunding goal smashed within a day

Go host yourself with a tiny low-powered Arm cluster in a box for $219

The Turing Pi 2 crowdfunding campaign has soared passed its $64,000 goal in a single day, currently standing at $1,027,428 with more than 3,400 backers.

Early-bird backers will be able to build their own Arm cluster in a box for $199 (compute modules come extra). Now the entry-level pledge stands at $219 for one Turing Pi 2 Cluster Board.

We covered the Turing Pi 2 at the end of last year and at last the waiting is over – in principle at least. It has been a year and a half since Turing Machines initially announced the product, and a good nine months since it published the specifications.

The Turing Pi 2 supports the Raspberry Pi 4 Compute Module (CM4) via a $10 carrier board. However, the CM4 is out of stock at most places we looked, so unless you happen to have a couple just lying around, you might need to look towards some of the other supported processor modules.

The good news is that there are a variety of them, and some of them are in stock in a few places online. The bad news is that they cost substantially more than the budget Raspberry Pi range… which may, of course, be why they are still in stock.

Alongside the RasPi CM4, Turing Machines' latest announcement also described its own RK1 processor module, which is to have a Rockchip RK3588 SoC, with four Arm Cortex-A76 performance cores and four Cortex-A55 efficiency cores and up to 32GB of RAM. We don't yet have definite pricing for this, but the company told us that they hoped it would be in the region of $150 for a module, with 16GB of LPDDR4 RAM and 16GB of eMMC onboard storage.

As well as these, the Turing Pi 2 also supports three different Nvidia Jetson development boards: the Nano, TX2 NX, and Xavier NX. We found the latter two models on sale online at a bargain-tastic $260 and $730 respectively.

This is a Kickstarter campaign so you should not expect shipping to be immediate. Possibly, by the time stock is available, there will be a selection of brains to choose from.

According to the company's short list of FAQs, it is possible to run with a mixture of dissimilar boards, and Turing Machines confirmed to us that "you can start even with one compute module, though it does not make much sense."

It added: "In order to build a Kubernetes cluster, it's recommended to have at least three nodes. Getting the CM4 is a bit challenging right now; however, we are building relationships with the largest suppliers and the RPi Foundation to be able to secure compute modules for every backer who needs them."

In addition to the board and some compute modules, you will also need a mini-ITX case to house the system, a power supply, and probably some additional shared storage for your micro-cluster.

This isn't going to be the cheapest way to build your own K8s cluster, but on the other hand, it will be one of the smallest, quietest, and lowest power-consumption clusters out there, so it will be one of the cheapest to run. ®

  • Restructure at Arm focused on 'non-engineering' roles
    Meanwhile, CEO wants to vacuum up engineering talent amid return to stock market

    Updated Arm today told The Reg its restructuring ahead of its return to the stock market is focused on cutting "non-engineering" jobs.

    This is after we queried comments made this morning by Arm chief executive Rene Haas in the Financial Times, in which he indicated he was looking to use funds generated by the expected public listing to expand the company, hire more staff, and potentially pursue acquisitions. This comes as some staff face the chop.

    This afternoon we were told by an Arm spokesperson: "Rene was referring more to the fact that Arm continues to invest significantly in its engineering talent, which makes up around 75 percent of the global headcount. For example, we currently have more than 250 engineering roles available globally."

  • Arm says its Cortex-X3 CPU smokes this Intel laptop silicon
    Chip design house reveals brains of what might be your next ultralight notebook

    Arm has at least one of Intel's more capable mainstream laptop processors in mind with its Cortex-X3 CPU design.

    The British outfit said the X3, revealed Tuesday alongside other CPU and GPU blueprints, is expected to provide an estimated 34 percent higher peak performance than a performance core in Intel's upper mid-range Core i7-1260P processor from this year.

    Arm came to that conclusion, mind you, after running the SPECRate2017_int_base single-threaded benchmark in a simulation of its CPU core design clocked at an equivalent to 3.6GHz with 1MB of L2 and 16MB of L3 cache.

  • Intel is running rings around AMD and Arm at the edge
    What will it take to loosen the x86 giant's edge stranglehold?

    Analysis Supermicro launched a wave of edge appliances using Intel's newly refreshed Xeon-D processors last week. The launch itself was nothing to write home about, but a thought occurred: with all the hype surrounding the outer reaches of computing that we call the edge, you'd think there would be more competition from chipmakers in this arena.

    So where are all the AMD and Arm-based edge appliances?

    A glance through the catalogs of the major OEMs – Dell, HPE, Lenovo, Inspur, Supermicro – returned plenty of results for AMD servers, but few, if any, validated for edge deployments. In fact, Supermicro was the only one of the five vendors that even offered an AMD-based edge appliance – which used an ageing Epyc processor. Hardly a great showing from AMD. Meanwhile, just one appliance from Inspur used an Arm-based chip from Nvidia.
