Today we are thrilled to announce the Turing Pi V2. The Turing Pi V2 is s compact cluster in a mini ITX form factor with 4 x cluster nodes, 2x mini PCIe (Gen 2) ports, 2x SATA (Gen 3) ports, and new Raspberry Pi compute modules 4 support. The Turing Pi 2 cluster is architecturally similar to the AWS Graviton clusters. The CM4 processor uses the ARMv8 architecture. You can build images and applications for AWS instanc…

This is very neat.

I’m sorry if I missed it, but have you announced pricing?

Stupid question, how do these 4 SoCs share the 2x SATA ports? Do you assign them to a specific processor somehow? Are the other machines booting off of PXE boot?

The blog post[0] answers that: peripherals spread between nodes.

Besides academic uses to perhaps teach distributed systems on these are there any real world use cases for these clusters?

I use mine to host some non-revenue-generating websites (they are super cheap for that purpose), and also for some ARM image builds that I integrate into my Docker/Kubernetes pipeline. I haven't yet moved to ARM CPUs on AWS for some of my projects, but may be able to more quickly if I can have a local cluster like this for testing that isn't as slow as the CM3+-based one the Turing Pi V1 supported.

i often see people claim raspberry pi cheap but in reality it's not. a cluster like this is probably not cheap and performance wise, it's slower than, say an AMD x86 system.

IT's amazing device!

For now i'm running a few RPi devices and i was dream about such device to put them in for more processing power.

Earlier quoted context omitted.

You could get an off-the-shelf x86 machine in the same form factor and run the cluster nodes in VMs, for instance. Maybe you could argue that four RPis on a network are more reliable than a single x86 with VMs, but that doesn't seem to be the point of this machine.

That's one of the point too. We have industrial customers who deploy apps in the places with a limited access to the internet, so increased reliability something important to them. Another thing is that they can host apps with different purposes on different nodes in containers. Besides that all the infrastructure could be managed with a tool like Kubernetes and organically work with existing cloud infrastructure. An…

That's really nice. There are high-end products out there with redundant backplanes (dual or triple) and redundant PSUs (2 or more). To match that level of redundancy it seems you would need 4x Turing Pi, to be able to survive a simultaneous failure of 1x arbitrary PSU and failure of 1x arbitrary backplane (ie. the integrated RTL8370 GigE switch).

The 2x external GigE ports on the Turing Pi helps a lot, in that each cluster can connect simultaneously to 2 external GigE switches, in case one of those things fails.

Could be an interesting exercise to set up and get it all working, in particular K3s + dynamic routing might be a fun challenge.

Out of curiosity, does the firmware in the Compute Module allow for PXE boot?

Would be a neat way to handle corruptions of the SD / eMMC. Flick the power off through the Turing Pi's I2C, have one of the other nodes act as a PXE server, flick the power on again to the affected node, and have it pull in a tiny kernel and init-script through PXE that flashes the SD / eMMC with an image from the PXE node.
