Building a 600 CORES - Supercomputer to mine VeriumReserve

[cryptovagas]

Actually "it should". And now it's up with my custom miner/kernel dedicated to vrm. So now it mines just vrm.
Price is setted high because i prefer none rent this until i start getting my first solo blocks (but yeah, if you rent it at this price for vrm, it switches for vrm)

wish you success there, but if you ever wanted to rent, you can count on me too

Well it's on MRR now 
Can change algo upon request if necessary, but you guys should let me know

If you're able to change it for Garlicoin let me know! Would love to rent it for a few hours! Can send a PM if interested! Or if you have discord?

As you wish, i prefer PM

That's it ??
After 10 pages of how you build your supercomputers... nothing more ?
Can you share with us your stats ? your profitability ?
What is your energy consumption ? .
I know we can rent your supercomputer, but why do you have choose to rent it , why don't you use for yourself 24/7 ?
All the Odroid work great, no troubles ?

Thanks for all these information ! But after all your work on it, I think the end is too short... need more info !

In fact, I was just to write a message!
Well, how is going?

I've had to shut down Sally because of power issues. Again? YES. But now the problem wasn't the PSU, but the cables and the power distribuitors panels on my rack. Those boards were bottlenekking the ability of current to pass trough, causing an huge power dispersion in terms of current and heat.

Solutions was this:
- 4 huge blocks to distribuite the power
- 2 pairs of 20mmq wire in order to attach the psu

Current can flow nicely now. Just had to rewire everything from scratch!

Energy consumption was around 1300 watts. But now that should be rechecked again!
All SBC works always great! (but if the power is not good,they won't! )

I've run it stable from 01/02 to 9/02. Got almost 1 block/day.

Atm is on MRR just because i can switch pool/host and monitor stats while I'm away. Rent price is setted high. Just to be sure none will rent it

What board you use to put processor? Any brand? Can you take picture board of cpu. I'm still cannot see how the setup is.

Wow ... just stumbled upon this thread.  Your old posts on Steemit got me into mining Verium.  I only have 6 Odriod, though, expandable to 23, LOL.  Still, it's profitable, just not getting rich.  But they are quiet and are not running up the electric bill.  Your new miner is amazing.  Best of luck to you.

Hola, I'm not birty from steemit, just a friend of him

Hey man any update ? Power issues already solved ? I was think about doing something similar but with S912 - 8 core - 2GB

[laineux]

Hi

Some news to share with us ?

Thanks

[jacko0088]

Received TONS of eth plugs, cables and accessories for today. Unfortunatly my shipment from Poland will take two days more.  Undecided


Ethereum doesn;t

Doesn't what? Still mining good so far

Goodmorning everyone

sorry my bad english google translate from italian.

congratulations for the work you are doing and the passion you are putting

I can not create the image of ubuntu 16XX is constantly restarting someone has suggestions?

I thank those who can help me

If the image isn't corrupt and was burned to the sd card properly, it is most likely one of two things (I encountered both with my odroids):

The sd card isn't fast enough (odroids need Class 10s in my experience, with Sandisk working well for me)

The power cables from your PSU aren't a high enough gauge (write the company you bought them from and find out, they need to be 18AWG or larger)

Have you tried a different image? One of the odroid or mining pre-fab ones perhaps?

[spiritobiker68]

Thanks for the reply

I tried with three different power supplies, one even with a modified computer power supply and 5V pickup.

I tried with different images 15. 16. 18. but nothing same problem

the sd was created with notebook and ubuntu operating system

now I try to change the jack cable

I have not been able to use it yet.

the strange thing is that sometimes he left and after a sudo apt update / upgrade started to reboot continuously

Can you test a completely different sd card? It may just be a bad card or a make or class that isn't working.

Also it may very well be the cable. Here are the ones I used that actually worked (went through two other sets before I found them):

Also you may want to check the odroid forums as well, their support personnel actually respond to threads there...

[spiritobiker68]

thanks for the collaboration I solved:

I replaced the cable with the connector and it worked without reboot,

actually the cable files were too small.

Thanks again .

now I have another problem with cpuminer.

"scrypt buffer allocation failed"

I solved half of it but I do not like it by halving the threads at -t 4

Can you drop here the miner starting line? Also make sure you have enough ram available

[spiritobiker68]

Hello,

the command line is : ./cpuminer -o stratum+tcp://stratum.beertendr.com:3334 -O Weblogin.WorkerName:WorkerPassword -t 4

if I do not apply the option "-t 4" the following error appears:

"scrypt buffer allocation failed"

So then include it? Good call on beertendr, by the way, they're the only pool I've found that registers my hashrate correctly and pays out accurately. I earn 3x what n3rd3d was paying out on beer.

You will also get a better hashrate if you use fireworm's version of cpuminer in case you aren't already. It can up it as much as 20%.
