Calxeda has been building 16 core cards[1] for awhile now with about 18 fitting in a 1U-sized box[2], each card connected by 10GbE similar to this[3].

Not to mention Tilera, who makes 36-core chips/cards [1], with 4 in a 1U box [2], with each processor with connected to each its four neighbors by a 250 Gb/s link.

Interesting that these can run a single OS as a huge multi-core machine.

It might be worth pointing out that TileGX isn't ARM.

It is an interesting system though.

But Tilera uses its own architecture, ARM on the other hand is nearly everywhere.

There were other companies like Tilera: Transputer, Connection Machine.......SiCortex was founded in 2003 with a similar idea and was shutting down by 2009

The problems with these architectures is cost: mass market tech like x86 and ARM offers more bang for your buck

HP has also been working on Project Moonshot which (I believe) is based on Calxeda.

And you can buy them where, exactly? :)

Boston Limited should be shipping Viridis units now [1][2].

Yeah, I see they have the same sort of "talk to us for pricing and more info".

Important things to note is that each of the nodes in this Slab have their own local SATA solid-state storage, and the individual CPUs are quicker. The Boston thing has higher density though.
