there is a nice bunch of remote listening designs with PIs around. Lets say, have 8 software decoding channels of RX in a single compact box as an Ethernet attached web GUI control. Use each of the channels for decoding e.g. AM, FM, side-band modes, CW or the modern merely automatic digital modes.

This is really cool.

Would be great for a little home cluster! I think six nodes would be ideal for me though, but that might be a bit tight on a mini ITX board.

You node it's serious when it has an ATX power connector... But seriously, this board ticks many boxes people have been asking for

[@RedMageGaming]

So... lets math this out. Turing Pi 2 Mobo, $200, $10x4 Pi CM4 Adapter boards, power supply $30-$50, Case $0-$200 CM4 boards x4 $35-$85 depending on where you get them and what version you get, we'll say another $100 - $150 on the low end for SD cards / or SSDs etc. Looking at a little cluster in a box for $500 to $700. Fairly expensive but considering the learning potential and the small size and flexibility, actually rather cheap. Totally worth it for all that you can learn on it, basically a homelab in a box.

[@JeffGeerling]

you're spot on with the estimate!

[@xaty1808]

For less than € 200 you can buy a chinese motherboard with 2 intel Xeon E5 processors = 24 core each and 16 Gb memory…

[@RedMageGaming]

@@xaty1808 Sure, but that's not the aim here. This is more bare metal cluster, not a machine that can virtualize a cluster. It's not about the performance per $ spent. It's about the environment that you can build to learn and test clustered sytems. You could also easily buy 4 older small form factor business desktops for about $50 each and cluster those, and have the same rough environment. But it will take up far more space and draw more power than the pi cluster ever would. So it's really about where you want to spend your money.

which is why clusters only make sense when you need more power than you can get from one server. Which is why small clusters are just pointless.

Really interesting for home use, just wish there would be CM4s with more memory, I don’t need alot of compute power, but need more memory, this would be really sweet if the PIs had 4x16GB or even 4x32GB memory, for running k8s nodes. Here in EU, power usage quickly get stupid expensive, this would fit well for that.

[@sugoruyo]

What workloads are you running that you need 64/128 gigs of RAM on a Pi? I suspect, even if those existed, you'd find the CPU and memory bandwidth on the Pi can't keep up at that point. You're probably better off looking outside the Pi family or even expanding cluster size (or multi-clustering) if your workloads can be broken down.

[@ruprecht9997]

Pity that even Jef likes to pretend that four RPI4 becomes a "superomputer". This channel is more about all the improbable things one CAN use a Pi for, not what makes much sense. If you want hardware with usable performance, buy used professional hardware from ebay. I got me a couple of 12 core HP DL-380 servers for about half the cost of four RPi 4. Oh, so they consume a couple of hundred watts each, but you can run real loads on them. Those 12-core servers, actually are "super computers", in that their CPU's DO share ram and resources. Then you section them up with ProxMox and play with Kub all you want. :-) The "limited budget" argument isn't particularly valid I think, given the prices of used professional hardware.

[@The1stImmortal]

On the PCIe, would be nice to have some kind of pcie switch onboard that lets you map peripherals to slots using the firmware, but this is a clever solution nonetheless

[@yaolet]

Jeff has a very good point here: m1 macbooks are more power efficient comparing to pi. I've seen people justifying pi's horrible desktop experience with saving power. lol that's not true at all. It would be something if apple would one day release something like a M1-compute module, but alas that day will never come.

[@dieSpinnt]

There is no need to think about the hearsay from others, like the irrational justifications you pointed out (which made me laugh, BTW. Thanks:) ) Let's just stick to the truth and the facts: Raspberry Pi < $100 vs. MacBook M1 > $1000. There is no need to compare Apples and Pears ... (pun intended:P hehehe). I second your thought about "Maker-Stuff" from Apple. The company would have to publish circuit diagrams and treat its customers like people and not incompetent idiots from whom they have to protect their "important secrets" (as usual nowadays, "The right to repair", LoL). That only happens when hell freezes over:) Thanks for your comment, Zhen:)

Parallel computing with overset grids for computational fluid dynamics is a great reason for clusters. By dividing huge grids that won't fit on one node (memory wise) into much smaller subgrids each fitting on one of many nodes, very large CFD problems can be run. NASA has been doing this for decades but with much larger and much more expensive computers. This was how the flow field around the space shuttle was computed back in the '80s.

Very nice content, thanks for taking the time to inform us! However, looking at the technology; I really wonder what the benefits would be. No doubt that board + 4 pi's and so fort, costs about the same as a ryzen 7 mainboard and a cpu with 8 cores. I don't see the advantage. At all. The pi is limited in bus width (pci express lanes), not really expandable easily, and is non-standaard ARM hardware. Also, that ryzen setup woud totally trash the pi performance wise. So I don't see any advantage or reason to want to do this. If you want to run a cluster so bad, you could also run VM's on a normal PC setup. And they would still easily outperform the pi.

[@VD-cc4hx]

21:11 it can be used as a cheaper diy network server that runs on pie instead of a more expensive pc. pushing low end hardware is fun for hobbyists and is why the pie exists in the first place. this could also be for those who don't want to have a cloud based solution. a cheap chinese mobile phone has more power, but you don't see that being used anywhere for these things.
