Running a 6 node cluster of Pi4s at home now. Did some benchmarks. Long story short. USB thumb drive boot disks are better performance and cheaper than SD cards. Fans are completely unnecessary on a Pi4 with an aluminum heat shield style "case". They do run hotter than with a fan, but they will not be heat throttled with recent firmware.

Example case which does away with the need for fans is: https://www.amazon.com/Geekworm-Raspberry-Computer-Aluminum-...

I use one of those for my headless dedicated Pi4B website server plus UPS controller.

Admittedly, that's a simple load, but my Pi never gets over 42 degrees C, in a tropical area, averaging around 30 degrees C.

Why there is so much love for such project where someone connected a couple of ready made things (maybe except the case) and everyone gets excited?

The hotswap 3D printed mechanism is pretty neat (reminds me of the swappable harddrive days). As for Rpi clusters, its just a neat idea to think about. It's not entirely trivial hardware or software wise to load balance 14 Rpis for "one purpose".

Surely one could make do with passive heatsinks on the Pis and use the back coolers?

Posted before I saw this comment. Yes passive cooling is fine with recent firmware and a good heatsink case. I have stress tested with the following case for hours with all cores pegged at 100% and there is no CPU throttling with passive cooling. They do run hotter, but they do not throttle. Old firware and bad cases will though. https://www.amazon.com/Geekworm-Raspberry-Computer-Aluminum-...

You wouldn't need that much in their case (sorry) as they have through flow.

You absolutely could. But you wouldn't learn how to build a system that recovers from yanking a power or network cable, wouldn't own it, and wouldn't be able to run it on your terms. You'd need a credit card with an American-run payments network to operate, with a declared identity and a bank account, for which a prerequisite is a few months of stable living and income in a particular jurisdiction, itself something l…

This sounds like some kind of fantasy; how many people without stable living conditions or without a bank account that can be processed by the US are concerned with...cluster computing? "What about all the homeless Iranian Ferrari owners!" doesn't seem like much of a rallying cry.

Surely if there is even 1 unbanked person in existence that is interested in cluster computing, then this is a worthwhile endeavour.

I like this one, a little more expensive but makes the Pi into a NUC style SFFPC: https://www.waveshare.com/pi4-case-argon-one.htm Edit to add the fan is optional, so it can run fanless with no throttling.

That’s good value with the 2 hdmi adapters

Try being from a random South Asian or African village. Tell me how you go buying cloud services with your nonexistant banking infrastructure and personal credit line.

The physical location of a person isn't generally the key barrier to being unbanked; instead it's poverty.

"The most common one was having too little money to use an account. Two-thirds cited this as a reason for not having a financial institution account, and roughly a fifth cited it as the sole reason. Cost and distance were each cited by about a quarter of those responding to the question, and a similar share said they do not have an account because a family member already has one. Lack of documentation and distrust in the financial system were both cited by roughly a fifth of adults without a financial institution account, and religious concerns by 6%."

(And to state the obvious: poverty is also a barrier to owning physical infrastructure)

No, try buying cloud services while living in a remote village where clothing is non-existent.

What could you do with a similar setup? I mean: what's the purpose and/or the advantages compared to a "classical" solution ?

It’s fun to hack together. Not everything needs a clear business case with strong ROI.

This. I think the Hacker News mindset has substantially shifted in the last few years from the "Hacker" mentality of doing things because they are fun and knowledgeable, and more towards Enterprise News..

Not everything needs a business case, some things (most things) should be done just because you want to see if you can.

If someone really needs to think in items of ROI and that everything needs a business case, then this ideology of doing things for fun and testing limits is the only way to really innovate.
