Marks Rpi Cluster continues running 24/7. For the last month or so its been running the Einstein@home BRP4 app. The Pi3's have a RAC (recent average credit) of 900 credits and the Pi4's are hovering around 1900 credits. The Pi3's are only running 3 at a time due to their limited memory, the Pi4's are running 4 at a time.
Turing Pi
They sent an email on the 6th of May officially announcing the Turing Pi 2 Cluster board. Its a Mini-ITX sized board with a 1Gbps managed switch, 2x Ethernet
ports, 2x SATA3 ports, 4x USB3 ports, DSI and HDMI port, SIM card slot, two mini PCIe slots and holds 4 Pi CM4 compute modules or their RK1 compute modules. Its powered via a standard ATX power connector.
You will need a PC case and power supply. Note if using Pi compute modules you will also need to purchase the adapter boards.
They also announced the Turing RK1 compute module that can be used with the Turing Pi 2 Cluster board. The RK1 has 8 ARMv8 cores (4xARM Cortex A76 and 4xARM Cortex A55) with up to 32GB of memory.
See Turing Pi for their announcement.
For what its worth I am not planning on getting one of these as I prefer to use the Pi4. While this sounds like a great idea I can scale to more compute nodes simply by adding more Pis.
Update 14th of May
It seems Turing Pi had some delay getting registered on KickStarter. That has now been rectified and their latest email (below) has the details.
