how does the whole thing behave if i use e.g. 2 gekko usb hubs with 3 compac f each?
does each hub then have its own mining power from the 3 miners in mentioned or can the mining power of the two hubs, which is generated by the 6 miners, be merged?

All miners on all of the hubs are automajikly found and used by the 1 instance of cgminer. While each stick runs at its own (varying) diff and reports its own results, the total hash rate of all the miners are combined and reported as an aggregate hash rate.

cgminer has various options explained in the README to do various setups.

However, all miners connected to a single cgminer instance are treated as a single larger hash rate at the pool (as Fuzzy said)

If you wish individual miners/compacf's to use individual workers and pools, you must run a separate cgminer for each one.
Yes selecting which USB miners each cgminer will use, has been part of the code for a very, very long time

Also as mentioned before, the additions VH did were all added also.

@n0nce @sidehack
thanks again for your comments and advice
then i will connect my hubs each with this power supply individually to minimize any disturbances or failures

No, I just haven't updated my sig for a while. I've kinda given up on the upgrade kits, seeing as the last miner with that chassis stopped shipping like six years ago. There's some other fun stuff in the mix, and I'm hoping to have several product announcements between now and year's end.

I see, thanks a lot for the update! I feel like sub-1kW 'pod miners' are the best middle ground between low entry-cost (acquiring and running them) as well as low noise (relatively easy to cool) and still non-negligible hashrate. So I hope that's something you will be announcing.. Wink

Never got around to writing a Compac F review, but my biggest issue with it is that even if millions of it are running worldwide, the combined hashrate wouldn't amount to much more than a couple thousand industrial ASICs. It's probably not going to save the network in case of a coordinated attack from large mining operators, and users could gain more sats by buying $1 worth of BTC every day.
However, if you can manage to produce miners with +10TH, it's going to be a whole different story..

The issue with e.g. filling up a GekkoScience hub to its max and achieving multiple TH is simply the overhead (one PSU circuit for each chip) in hardware and thus in cost and probably cooling as well.

If you can, it'll probably be better to not daisy-chain your hubs though.

Also true. By the way; I always read your signature about the 200+GH USB stick (which I assume is the Compac F with actually 300GH+) and the '6TH volt-adjustable S1/3/5 upgrade kit'.
Anything new on that? Or is it classified? Lips sealed

edit: i have a question about the two gekko hubs. is it better to connect them each with a usb cable to the pc/raspi4 or is there the possibility of a usb splitter to which the two hubs are connected and from which only one usb cable goes to the pc/raspi4?

I only have one such hub but I do believe either should work fine. After all, you often don't even know for sure if what appears as '2 ports' on a computer / laptop / raspi isn't actually just an internal USB hub that bundles all the ports to one USB controller.
Actually, if I remember correctly, Raspberry Pi has just a single USB controller, so all ports are just one 'hub' anyway.

Quote from: https://www.hackatronic.com/raspberry-pi-4-specifications-pin-diagram-and-description/

USB Controller :

VL805 chip is the USB port controller for Raspberry Pi 4. The Pi has 2 x USB 3.0 and 2 x USB 2.0 ports. VL805 chip is a USB 3.0 Host controller. it allows the PCI Express platform to interface with USB Super-Speed (5 Gbps), High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) devices. The root hub is consists of four downstream facing ports, it enables simultaneous operation of multiple peripheral devices.

i'll get to work on this soon, when i have all the components together.
i think that if you have been working with BTCitcoin for years, you should also understand mining and at least have started/operated a small farm yourself to understand it even more intensively. it's not even directly about the matter of find a block, it's about the fun and understanding of the whole matter

I'm not sure offhand what options there are in cgminer but you should be able to isolate individual or collections of sticks to a single instance of cgminer. Our testers run a debian PC with two USB busses each piped to hubs, so we run two instances of cgminer, one locked to each bus using a command-line flag. VH's driver I believe had settings to load in sticks by serial number but I don't remember if kano carried that over for the Compac F driver.

In general, unless you specifically tell cgminer otherwise, it'll load in every stick on the controller and use them as a combined hashrate for the given pool connection, like /Fuzzy said.

No. Each worker (stick) is mostly independent of the others and are doing their own work at their own pace but acting together report results to the pool as a single user with multiple workers.

Ja, each hub must be plugged into it's own port on the PC. You never want to use just 1 port and daisy chain hubs one after the other.

so this also means that not every miner works for himself, but the entire hashrate is bundled together - do i understand that correctly?
and the connection is made individually from each hub to the raspi4 right?

Well, I finally get my Solo Mining setup working. I put a 120mm fan in front of the Compact F and now its very cool (about 42°C). Didn't thought that would affect cooling that much. Without cooling at 200Mhz it's to hot to even touch the heatsink. Now it's running at 400Mhz. Maybe I go a little bit higher the next days.

But now I've found another problem with my setup. the latency to kanopool is quite high. As I'm from Germany, I use the server in the Netherlands. So I started some ping tests:

Code:

maik@ubuntuserver:~$ ./stratum-ping us-east.stratum.slushpool.com:3333
...
avg 109.028696ms

maik@ubuntuserver:~$ ./stratum-ping sha256.eu.nicehash.com:3334
...
avg 25.584321ms

maik@ubuntuserver:~$ ./stratum-ping stratum.antpool.com:3333
...
avg 20.263655ms

maik@ubuntuserver:~$ ./stratum-ping solo.ckpool.org:3333
...
avg 97.443751ms

maik@ubuntuserver:~$ ./stratum-ping nl.kano.is:3333
...
avg 246.267585ms

Maybe it would be better to mine with my own bitcoin node? But my node is bitcoin core 22.0 wich doesn't work with cgminer Undecided

Which bitcoin node version uses kanopool?

Um, you must be doing something terribly wrong with your internet or there's something wrong with the program you are using to test.
If you are using a VPN or Tor or other similar delay on your data, then that's a really bad idea and the cause of your terrible latency,
and on top of that, your ping values are meaningless since they will change regularly when using such connections.
If this is the case, then yes please don't mine on KanoPool with those added delays.

From the German (frankfurt) node to the Netherlands (amsterdam) node in only a 7ms ping.
Again, if you are getting a 246ms average ping, then you are doing something terribly wrong with your internet.

Where are you looking for stock? Here's the official resellers.

Quote from: sidehack on July 10, 2022, 01:51:44 PM

It's always best to buy from 419Mining, ASICPuppy, MineFarmBuy, BitcoinMerch, Eyeboot or bitshopper.de because those are the guys I've trusted for years to take care of things for their people.

Can somebody give any information on when the Compac F is available for purchase. So far I have only seen it out of stock or with a much higher price on eBay.

It could be an old Compac just running like balls under the wrong cgminer, detected as an Antminer U3 pod via Icarus.

@ Cygan
Your post is off-topic.
Since that is NOT one of Sidehacks's Compac sticks you need to create a new thread for it. When you do it would greatly help if you tell us just what it is...

AU3? Either that's not a Gekko device, or you're using the wrong version of cgminer.

this is not a gekko comac f, but one of the very first usb miners... Grin

since some time i get the following error messages, which sometimes disappear again and then reappear.
can someone explain to me what it is and how i can turn off the error?
