Hello,

I installed my own bitcoin mining pool using unomp (ubuntu VM) and I now try to run cgminer to test GPU mining on it.

I am new in mining, and do not manage to make cgminer run...

Here is my actual .bat


Code:
DEL *.BIN
CLS
@ECHO ON
ECHO.
setx GPU_MAX_ALLOC_PERCENT=100
setx GPU_USE_SYNC_OBJECTS=1

timeout /t 4

cgminer.exe --scrypt

and my cgminer.conf file :

Code:
{
"pools" : [
{
"url" : "stratum+tcp://192.168.1.13:3032",
"user" : "toto",
"pass" : "foobar"
}
]
,
"scrypt" : true,
"intensity" : "20",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "0",
"thread-concurrency" : "24550",

"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}


But I got errors :

What did I miss?

I hope this isn't a dumb question...

Going through some of my debug logs, I noticed that the generated stratum header has the version like this:

[2018-02-15 23:08:23.772] Generated stratum header 20000000ed37665c908b8f6b9120d09918afa1ef1c3bd3fa0024d3f700000000000000005fb360c99001606 f4f9aeb9293c5776d6e3e666adf0e6dacdbb9526ae3561fa95a86592f1761e9f800000000000000 8000000000000000000000000000000000000000000000000000000000

Shouldn't it be like this?:

[2018-02-15 23:08:23.772] Generated stratum header 00000020ed37665c908b8f6b9120d09918afa1ef1c3bd3fa0024d3f700000000000000005fb360c99001606 f4f9aeb9293c5776d6e3e666adf0e6dacdbb9526ae3561fa95a86592f1761e9f800000000000000 8000000000000000000000000000000000000000000000000000000000

I didn't see anywhere in the code where the bbversion was reversed.  Unless I missed it.  I did see some previous posts from way back where the block version is shown in the logs like my second example.  

The version gets put in the header_bin as in the first example, not reversed.    Raw block headers have the version reversed and when test hashed, produce the correct hashes.

Thanks,

Take a look at some blocks to see what version looks like these days, eg:
https://btc.com/00000000000000000077140243064000ba35b22d3e2440e936a722b90cd09365

Compare with older blocks, eg:
https://btc.com/00000000000000001ed61d4b7dd337c8eb1de0f21a0bd310a8733fb35f21991c

Thanks ck!

My question was geared more towards how the version is placed into header_bin, pool->header, and eventually work->data prior to being hashed.

The older block you listed gets hashed as:  https://blockchain.info/block/00000000000000001ed61d4b7dd337c8eb1de0f21a0bd310a8733fb35f21991cformat=hex
02000000ea7ee4542a0d7496954302e67b99a4d1a3d1c2724f8ddb1a00000000000000007d28ed3cb6e06dc df8267afaa908999d48f2d4deba94b4e344c3e126a3c8b00b174e1f54e9db2418e5bc702

The newer as (and current blocks):  https://blockchain.info/block/00000000000000000077140243064000ba35b22d3e2440e936a722b90cd09365?format=hex
00000020633a9073c5b1a5f32afefa4c1116c5bb9c593dfa419812000000000000000000515b81eeca6c575 93c90264ee1a1cb581fc3b7052e8adc23ec16db9917cf828bd33d575ac19100184dbccd28

Current blocks manually double sha256 hashed give correct results with the second format.

I guess I am not seeing in the code where the version is flipped after it is placed in as "20000000" prior to being hashed.

Thanks again for your help!

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.
