I appreciate the reply, fire219. That's a great rundown of ideas, etc.

I still would love to see a PCIe card and drivers to serve as host for SoPine; I think you could comfortably fit four modules, with proper spacing for passive heat sinks, on a full-height and half-length standard format card.

Power supplies. How many people with SBC clusters have had to kluge together their own? (me! My A64 cluster is powered from a USB hub; awkward but effective) Also handy for any PCIe card(s) that need power not available from the SBC.

We have a power supply designed exactly for A64 cluster use.

::BUZZER:: Nope. That's a power supply for a single clusterboard. My minicluster is made of four Pine64 A64 512MB boards, individually powered via cable from a USB hub (network switch and mini-router also powered from same source!) I've had it since shortly after the original Pine64 board was Kickstarted.

I was thinking something more along the lines of a 120vac (US) or 230vac (EU, NZ, etc.) buck/boost switching 12/24/5.5vdc supply of 100+ watts, and appropriate cabling, such as this:



Of course, if there aren't enough individual orders of multiple-SBC boards, it wouldn't make any sense to put it in the store. I get it.

How is the Pine64 in a 4-node cluster configuration like yours? 

I have a small Raspberry Pi 3 cluster (2-node) and a old and ancient PC cluster (8-node made of PII/PIII processors) and have thought about getting the Pine Clusterboard to replace my old PC-based cluster for the energy savings alone!
