OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[+POOL]

Hi cgminer devs,

someone sells modded firmware for antminer d3 on ebay... as far as i know this contains modified cgminer and your source are under GPLv3.

https://www.ebay.de/itm/AntMiner-D3-Custom-Firmware-50-Stromkosten/162961717033?hash=item25f1467729:g:XuIAAOSwihpataEA

best regards

Dragonmint T1 driver and asicboost rolling support for cgminer is now part of the public master cgminer code.

Why is the API in Restricted mode?

You choose the settings for the API. Not sure what you're talking about but my guess is you're talking about some hardware specific implementation of cgminer; that's nothing to do with me.

this is only for mining BTC ?

is there another algos ?


i have custom FPGA boards and i can connect to my FPGA with cgminer by using usb com port
it is minnig but very low hashrate so i need to mine different algos.

Yes

No.

Then you're asking for help in the wrong place.

At what point in the mining cycle do new mempool transactions typically get added to the Merkle tree of a candidate block and what variables govern this?

Is a mempool snapshot taken once and then mined until a winner arrives or is found?
Or does cgminer continually add new transactions to the existing block opportunistically? If so is there any impact on the hashing speed due to the re-computation of the header? Maybe there isn't since the CPU can do that, while the ASIC does the mining? I suppose that would be an opportunity to reset the Nonce too.

Thanks for any insights, I am not a miner, but interested in the effect on the mempool and chances of a new TX getting into the next block.

The mempool snapshot is done at the server level in the bitcoin daemon which is handed off to the mining pool, about once per minute so they're always up to date. Cgminer is at the client end and does not do any of this unless you are solo mining with it.

Hi,

did anyone solved the problem cgminer crashes the Raspberry Pi? (Raspbian)
After putting slub_debug=FP into /boot/config.txt systenm holds for about 8-24 hours then crashes on kernel paging:

Jun  8 12:00:20 RPinode kernel: [50708.328638] Unable to handle kernel paging request at virtual address 223fab15

I could find many other people having the same but no definitive fix or workaround

It's a linux kernel crash; i.e. an operating system crash. No userspace program should be able to do that so it's not cgminer at fault.

Thanks, but I was trying bfgminer and it works so they maybe did some workaround

They don't use direct USB drivers. No, I'm not rewriting anything...

Can anyone confirm this is legit link for windows binary:

There is no legit link for any windows binary any more. The only legit ones were on my website, and antivirus scans falsely tagged them as malware and there was no way to appeal the tag so I've given up on windows binaries entirely and removed them all from my site. Anyone mining today should be mining with linux and most hardware is using a controller device that already runs linux.

I've tagged a new version - 4.11.0 - the first in a while. Apart from numerous small bugfixes, the main new features are the Dragonmint T1 driver and the coinbase decode option. As you're unlikely to use anything but the latter, I've summarised the basic instructions from the README here:

Q: How do I use the --decode function to decode a pool's coinbase?
A: You need to have a bitcoind with server functionality and pass it the
credentials as the first pool in your config, and pass the pool's address that
you wish to decode as the second pool configured. Note the bitcoind NEEDS the
http:// prefix.

e.g.:
./cgminer -o http://localhost:8332 -u user -p pass -o solo.ckpool.org:3333 -u 15qSxP1SQcUX3o4nhkfdbgyoWEFMomJ4rZ --decode

EDIT: Updated to 4.11.1 for a missing bugfix and included NEWS outlining changelog.

Hi all,

I have added cgminer support to rig-monitor. Check here: https://bitcointalk.org/index.php?topic=2128602.0

Hi ck, you uploaded this file, here?: m.majorgeeks.com/files/details/cgminer.html
Or was some other people.

Nope. Only the one at http://ck.kolivas.org/apps/cgminer/ and the source https://github.com/ckolivas/cgminer is uploaded by me.

i noticed something strange with the started time/date, it shows

Code:

 cgminer version 4.11.1 - Started: [1970-01-01 01:38:34.881]

on one system, and

Code:

 cgminer version 4.11.1 - Started: [1971-12-19 03:49:24.590]

on the other, maybe some bug? i get correct output from command date

Hi

Where download binaries CGMiner 4.11.1 for windows ?
