Building a 600 CORES - Supercomputer to mine VeriumReserve

Haha! "render some works"
What are you going to render? The entire world?
Just joking. You have something in mind and the informational thread you've made is awesome. I'd really love to see more from you and your works. Hopefully this whole thing pays out at the end. Good Luck, man!

Well sometimes we have to compute jobs for work, this will come really handy with mpich

Slovakia, yeah, maybe, buy you cannot beat power consumptions advantages with SBCs:)

Impressive, I am following this thread.

Wow - sounds interesting and ambitious!

And here I am - planning to use my old Core i3 laptop for mining VRM! Cheesy

But in my case I do have free electricity

Your project is interesting - it has more ambition than commercial purpose.
Have you written the mining software for ARM by yourself or built it from open-source repositories? Did you try to make ARM-specific optimizations?
Did you try to run other mining algorithms on ARM? Having a mining alternative, if Verium fails commercially, is paramount. I have done a little research about mining on alternative CPU architectures and found that SPARC architecture does not offer any advantage against x86 for most existing algorithms. Glad to hear that at least some algorithm is competitive on ARM.
I consider that your Internet connection is the weak spot - you would better organize a wired connection between the switch and Internet gateway.
Those AC-DC converters you using are LED drivers? I have read that such converters have huge ripple voltage and a server 12VDC PSU would provide much stabler output voltage.

I really love your pictures and install

Thanks for sharing !

PSU just arrived, a bunch of stabilized 5V 30Amps. Each one should keep up 10 sbc

Still waiting for the boards.

Any benchmark data of any trial working unit that you have? How much hash power would each core get?

Eager to try as well, awaiting full synchronization with network.

We normally think about ROI, but it's really not everything. What's the ROI on a TV, boat, or fishing pole? None Grin

But they're all fun. This build is really cool despite that and I'm glad you're having a good time building it!

I am very curious to know hashrate per core too !

This is just a crude test on one of my machine, tested on single core and several more core. Didn't show ideal scaling, but single core give like 300 Hash/m, did not properly optimize for remainder of the core addition test.

Single core test

More core scaling test

Cool, the verium vault 1.1, recently released, improves the avg hashrate, despite the old one!

Little pro tip: if you have less than 10khs, solo is more profitable in the long run ;9

Hi,

I've been thinking about building something like your project and currently working on a little rig with 14*XU4s in to test things out before going big. I'm in the same situation as you, not very rich, but want to build something to learn and have fun, and maybe even make a profit

I noticed you bought the HC-1 machines, and I was just wondering if you've asked Hardkernel about the upcoming MC-1. If you missed this I feel sorry for you since they seem to be exactly what we Odroid-miners want. Or perhaps you have a reason to go with the HC-1s instead?

The info I've found online mentioned MC-1 release in September but it seems like it's been delayed. I haven't contacted Hardkernel about it yet since I still work on my "standard" XU4 cluster. Check this article out:

Yeah, I've asked them directly. MC-1 will not get released soon, everything is delayed and they don't wanna tell us anything. Probably is canceled. HC-1 because of less noise and more stakeable.

Also, HC-1 are moooore easy to resell, who atleast they have a sata plug

I had 24 xu4 in the past. Sold in 3 days

Ok, time for update. Sally today got the power!

SBCs were shipped in two batches, no sign of the first one (where the controller is). The stupid USPS tracking is showing "pre-shipping" since 18/10/2017, but I'm sure it's on travel..maybe on a tortoise.. The second batch, sent with UPS, should be here in three days. But I can't do nothing until the first one arrives. Configuring the controller is a pain, and will probably take a whole day. I still have half of the OS to flash on 75 microsd. That will take some more time too.

Power supplies. two switches and the other 60 fans works flawlessly! 110 watts at the wall. Waiting for the boards now

Nice project you got there...been following this. I am a small scale verium miner too and very much excited to see the outcome of this project. Thanks for sharing.

used xeon cpu same cloud vps server?

Not worth the price. Also by further calculations the final power usage should be around 850 watts

jacko, you know, i think we are more eager than you to see results Cheesy

this is the only thread that i check daily for your update Grin

i am specially thanking you for making more ppl join the crypto world Wink

Well, thanks!
I'm still flashing the OS images, 75 do to and label. It's not fast. New "real life job" takes me basically all day, so things may'll be more slow. But don't worry, this will be always updated when i can!
