ARM YOURSELF! The Compute Blade is here. Full review and testing with #RaspberryPi CM4 and clones from Radxa, Pine64, and more! https://www.youtube.com/watch?v=rKDGlpnP-vE

Great review! I'm still waiting for my dev version
(no time to play with it in any case)
Why clusters? If your app is scalable, Max memory BW of one blade times # of blades = scalable BW. On multi-core max memory BW per core tops out at (total cores)/(Motherboard memory BW).
A little over simplified, but the more cores pushed into the CPU, the more the memory BW per core decreases. This is fine for bursty cloud/web stuff, but not for HPC.
