If I took a Raspberry Pi CM3 clusterboard (e.g.: https://www.cnx-software.com/2017/08/16/pine64-sopine-cluster-board-takes-up-to-seven-sopine-a64-systems-on-module/) and installed some SODIMM RAM into the slots, would they work?
Can you use a male to male DIMM riser as a high speed interconnect between computers in a cluster? You could get the lower latency than PCIe and a decent amount of bandwidth (according to kanewolf, latency is WAY more important than bandwidth).
So would that work?
For this to make sense, look at the EPYC's infinity fabric. You see how all the dies are connected to one another, why can't this work for compute clusters? Instead of having 1 master processor and multiple slave processors, why don't we have them equally connected so any processor can talk to...
