Building a 600 CORES - Supercomputer to mine VeriumReserve

[jacko0088]

RIG ON SALE HERE!! --> https://bitcointalk.org/index.php?topic=4500313

Hello guys!
I'm starting this thread because I want to keep trace of my work while building a 600 CPU cores cluster able to CPU mine VeriumReserve, render some works and other stuffs.

Concept of VRC/VRM is really impressive, especially the ASIC/GPU resistant algo and the unique binary chain, and I still think both are undervalued and only few peoples really knows what's going on with this coins.
(VeriumReserve main OP can be checked here --> https://bitcointalk.org/index.php?topic=1540023.2500;topicseen)

Initial investment, for me, it's huge. I mean, I work as an IT Technician and I'm 21. Pulling out 5500 € to build up something like this it's not easy. I'm not a rich guy, no rich family, nothing. Those are 5 months of wage spent in something fun, and maybe profitable too.

I've already have experience in this sector, my first mining rig was a 24 Odroid SBC's. Here's the reference, in the Italian channel.

Stop talking now! Those should be the final specs of "Sally". (Yeah, this will be her name)  

Sally will be encased into a rack, SBC's are odroids based on the XU4 model. (ameridroid is a cool website if you are searching for SBC in the United States!)

• 600 CPU CORES (downclocked at 1.9Ghz each)
• 150 GB of RAM
• 600 GB of space (8GB/sbc)

Internet connection will be provided by a single Odroid XU4 connected via WiFi to my router. Then, every other SBC will get wired connection from it.  

Cool and useful references can be found here if you wish to build up something similar: https://steemit.com/@birty (Thanks to Birty)

I'll try to keep things updated!
Thanks!

There are 34 shipments incoming, 3 of them just arrived. For now is just a bunch of cables, ethernet plugs and a ton of Coolermaster fans.
Those little babies should be able to keep everything cooled and nicely going.
The plan is wire those fans behind the boards. To avoid cutting the 3 pin plug, some female connectors are already on the way for a custom rewire of everything.



For power, a single 12V 50Watts PSU should do the job
Also amazon was a piece of cake, offering me a network kit (even if it's a shitty one) for just 5 bucks...added to the cart

This is 75 Odroid XU4 8 core systems to give 600 core total? Why do you downclock to 1.9GHz?

Yes, we're talking abount HC-1 modules. Well, downclocking them helps against thermal throttling at first.
Second is just about power usage.

The Samsung Exynos5422 processor comes with 4 big cores and 4 little cores.
First ones are the Cortex™-A15, which usually runs at 2.00 GHz, second ones are the Cortex™-A7, running at 1.4 GHz each.

Basically is like this:


[8 total cores]

core[0] 2.00 Ghz
core[1] 2.00 Ghz
core[2] 2.00 Ghz
core[3] 2.00 Ghz
core[4] 1.40 Ghz
core[5] 1.40 Ghz
core[6] 1.40 Ghz
core[7] 1.40 Ghz

Downclocking the first four ones, will save around 1Watt in terms of power usage (per board). And with only  5-6 h/m lost per board.
If thermal throttling kicks in, well you'll have everything forced to be setted more lower, like 1.4Ghz + 1.2Ghz. Maybe it could be more setting a performace mode using cpufrequtils but..I think it's not worth!

Anyway, if someone needs to know how to overclock or downclock those xu4 based boards, here's the code:

Code:

apt-get install cpufrequtils
cd /etc/default/
touch cpufrequtils 
nano cpufrequtils

Add those lines for 1.9 GHz

ENABLE="true"
GOVERNOR="performance"
MAX_SPEED=1900000
MIN_SPEED=1900000

And the trick is done

Nice Jacko,

Looks like Verium CPU mining is becoming really popular, network hash rate keeps increasing and we keep adding pools to the network.

http://veriumstats.vericoin.info/

Pools

https://pools.bloxstor.com
https://beertendr.com
https://vrm.poolinat0r.com
https://vrm2.poolinat0r.com
https://vrm.poolsloth.com
https://vrm.mining-pool.ovh
https://vrm.poolium.win


Our network consensus is better then most coins like ZEC which is worth 100x what Verium is worth with less development and technology.

With the new Verium Vault 1.1 days away, looks like things are going to take off!

[smoolae]

Seems like a really nice and fun project! Keep us posted, really eager to see the final result!

All the best!

[slovakia]

I'm curious about result ... good luck  
i help
your hashrate will be 475 H/s = 5 VRM daily = 9$ daily if diff will be still same (i doubt,cos raise) = your ROI= 722 days    better option is give your € to VTC,VERIUM on marketplace  
all this parameters/values is for free electricity

your rig = 1.2KWh x 24hours = 28.8kW for 1 day= 864kWperMonth

most customers in EU got 0.13€ perKW/h  = 112€ monthly for your rig


 

[okg]

nice thread!  looking forward to results

Verium it's maybe the main purpose for this build, but not the unique one! As I've explained so far, this will come handy while doing render jobs for work.
Some of your calculations are wrong, and maybe too much "good". I mean, having everything working will cost almost 280 eur/month in electricity
ROI is far away, yes, but I'm not here talking about ROI, money, profitability and so on. (As you can read from the disclaimer).

Anyway, don't worry, every single thing you'll see, every cable, every microSD, was very,very,very well preventivated and calculated

I wanna try keeping this as a "building up" thread as much as I can

600cores=75xu4= 75x16w=1200W=1.2kWh     your xu4 is any special? 

[nosanoko]

Holy cow! Once you're done, please let us know how it all went.

[jacko0088]

600cores=75xu4= 75x16w=1200W=1.2kWh     your xu4 is any special?  

Well, those are not XU4, the xu4 is the boards which those are based on.
A user already tested those boards, in terms of power consumption, comparing them into multiple cases, even when downclocked.

This is with 2.0GHz


Reference, thanks to JagDoc: https://www.planet3dnow.de/vbulletin/threads/428622-Odroid-HC1


ps: a XU4, on full load, doesn't reach 16Watts. My initial 24, were around 13-14 watts each.

[slovakia]

then your 600cores is how much SBCs? classic 75 pieces/8cores?
1 SBC how much hashrate= .ca 380 h/m?

1 SBC 12.2 wphour?  im think about 16 wphour

thx

1SBC is 1 odroid HC-1.
It's xu4 based, so it will do 380 h/m.

I expect 13W/each, no way a single one use 16W 

[slovakia]

then consumption will be better 75*13W=  91€ monthly for 75pieces=600cores

but ROI is massacer

you need electricity from ENEL

As I wrote, ROI is not the main point of this thread, but will come. Verium and vrc are two bombs ready to explode.
Tomorrow rack and components should be delivered, finger crossed.

600 cores ? am i reading this right?

[jacko0088]

600 cores ? am i reading this right?

Yup!

[Drawde]

600 cores with a 600 watt PSU is pretty amazing. I'm looking forward to seeing your final rig and results.

[snowyNNN]

I wish I had a machine like you´re building. Good luck!
