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

[Krak]

This is not a complaint or  request for help. First, i'm running 3.1.1. I just consolidated 7 ASICminer USB sticks that had been running fine plugged into various USB ports into one Anker 10 port USB Hub with a fan on it. I haven't gone on to 3.2 series because the Anker is USB 3.0. What i've found is that two sticks are only averaging 200Mh/s and are get significantly more HW errors than the others. They are ICA 3 and ICA 6, i find that the numbers are multiples of 3 interesting and thought it might of interest to  the Devs. Perhaps not. I'm going to let things run as is until it is announced that 3.2 series is USB 3.0 compatible. thanks for the great job guys.

Sounds like 3.2.2 has some USB 3.0 fixes; give it a shot.

Did I miss a mandatory upgrade? I am still using 2.11.4 and it is doing fine. I understood I need to upgrade for FPGA's or ASICs, but I am only GPU mining.

Same here, still getting the "idle more than 60 seconds" error and disconnections.

I build from source on Ubuntu 12.04 x64. Block erupters are connected with a USB 3.0 hub and function properly in cgminer3.1.1.

Time to downgrade again.

As I've been reading this thread over the last few months, it seems the 3x releases are geared more towards ASIC users, with little changes for GPU miners.  If things are stable, I'd stick with what you got.

i use a 7 port 2.0 hub that works nice with 3.1.1
3.5 A and only the two block errupter usb consume power. the ztex single and quad work nice with 3.2.2

How can I add pool with API?

I do it like this:

Code:

echo "addpool|stratum+tcp://pool.50btc.com:3333,15qSxP1SQcUX3o4nhkfdbgyoWEFMomJ4rZ,x" | nc localhost 4028
STATUS=S,When=1371415120,Code=55,Msg=Added pool 'stratum+tcp://pool.50btc.com:3333',Description=cgminer 3.2.2|

I see new pool in the list, pool is ENABLED but status is DEAD. When I add pool from cgminer GUI, it is OK, pool is ENABLED and ALIVE. I cannot find a way to activate a pool that was added through API, it is DEAD and I cannot switch it to ALIVE...

Could you check that cgminer API is OK?

UPDATE:
Stratum is troublemaker, getwork is OK:

Code:

echo "addpool|http://pool.50btc.com:8332,15qSxP1SQcUX3o4nhkfdbgyoWEFMomJ4rZ,x" | nc localhost 4028
STATUS=S,When=1371417076,Code=55,Msg=Added pool 'http://pool.50btc.com:8332',Description=cgminer 3.2.2|

When I activate debug, I see this (stratum):

Code:

UPDATE:
I cannot add p2pool through API:

Code:

STATUS=S,When=1371456527,Code=55,Msg=Added pool 'http://p2pool.org:9327',Description=cgminer 3.2.2|

Pool is added but is is DEAD and cgminer reports authentication errors:

Code:

 [2013-06-17 10:08:48] Switching pool 1 http://p2pool.org:9327 to stratum+tcp://p2pool.org:9327

What's the easiest way to run 3.1.1 and 3.2.2 at the same time on Ubuntu? I have 3.1.1 installed so that it launches when i type 'cgminer'. Can I run 3.2.2 from the source folder somehow?

[-ck]

Stratum is troublemakerWhen I activate debug, I see this (stratum):

Code:

 [2013-06-16 23:06:46] Failed to get sessionid in initiate_stratum

This is a harmless warning which is why it only shows up in debug. It means your pool doesn't support stratum resume.

I decided to try the latest CGminer in CrunchBang Linux with the default free "radeon" GPU driver instead of the commercial driver.

I installed all the pre-reqs and was able to compile cgminer without problem. But:

Code:

cgminer -n
 [2013-06-16 16:01:13] CL Platform 0 vendor: Advanced Micro Devices, Inc.                    
 [2013-06-16 16:01:13] CL Platform 0 name: AMD Accelerated Parallel Processing                    
 [2013-06-16 16:01:13] CL Platform 0 version: OpenCL 1.2 AMD-APP (938.2)                    
 [2013-06-16 16:01:13] Error -1: Getting Device IDs (num)                    
 [2013-06-16 16:01:13] clDevicesNum returned error, no GPUs usable                    
 [2013-06-16 16:01:13] 0 GPU devices max detected                    

Any hope? It's hard to find support online for this. Everyone in Linux seems to just use the commercial driver, let alone everyone using Windows. That's fine, but I'm checking if anyone has successfully done this. Or if cgminer just flat *requires* the commercial driver, which I may have missed.

I admit that without the "aticonfig" tool, I'm pretty helpless to even troubleshoot.

Many thanks--
============

Edit: Well this doesn't look good. I had glanced at this, but now I see more carefully, opencl isn't even seeing the 3 AMD 7790's I happen to have in this box. It's just seeing the CPU or MB graphics. I'll try a different/older AMD GPU card. Still, general advice on this appreciated.

You're screwed. It doesn't support OpenCL. You need the proprietary driver.

LOL okay thanks, boss, that's what I needed to know!

For what it's worth, I've heard reported that plugging the usb hub and devices from scratch after upgrading cgminer or restarting it helps. But I'm not making any promises since as I said in my announce there may still be issues with usb3 hubs (and specifically many usb1.1 devices which the erupters are). We shall keep looking into this...

[LukePFS]

Thank you for the update to 3.2.2. I had big Troubles on 3.2.1, every 2-3 hours crashing. This only with the machine I had the lancelot on it.

Now with 3.2.2 it running fine since about 15 hours.

Thanks again !

A little while ago the difficulty went up to 19.3M.

I'm running two instances of CGMiner 3.2.1 and they both reported going to 19.3M.  About 10 minutes later one of them went back to 15.6m.  And now about 15 minutes after that it went back to 19.3M.

Any idea what just happened here?  Has anyone else ever seen something like this before?
Thanks,
Sam

Can't imagine what happened there unless you have multiple pools that were disagreeing about what the current block is.

I cannot add p2pool through API:

Code:

echo "addpool|http://p2pool.org:9327,Lc8TWMiKM7gRUrG8VB8pPNP1Yvt1SGZnoH,x" | nc localhost 4028
STATUS=S,When=1371456527,Code=55,Msg=Added pool 'http://p2pool.org:9327',Description=cgminer 3.2.2|

I see this error in cgminer:

Code:

 [2013-06-17 10:08:48] Switching pool 1 http://p2pool.org:9327 to stratum+tcp://p2pool.org:9327
 [2013-06-17 10:08:50] Pool 1 difficulty changed to 210.767276
 [2013-06-17 10:08:50] Pool 1 difficulty changed to 205.967835

   "data": null,
   "code": -32700,
   "message": "Parse error"
}

I can add this pool from command line or from cgminer GUI, so login information is correct. When the pool is added through API, it is marked as DEAD and I see authentication errors.

It looks like cgminer has similar problem as cpuminer 2.3

I disagree, ver 3.0 IS superior for GPU mining. I noticed less crashing on startup, less submitted stales, etc.

[mishax1]

question here,

how does cgminer determines "Discarded work" ? (besides the words that say "work from block no longer valid to work on")

and could a long route / high ping / distance to the pool reflect on it ?

just want to figure out how does a 30% discarded work is different than a 0% discarded work (while both pools use stratum)..  

anyone ?
