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

Guy's

I have posted this before and i am posting it again.

Today i found a block and and cgminer api stats Found Blocks equals to 0. It happened two or three times since my last post about it.

something happened from 2.10.5 onwards

PS:

To all of you who use cgminer - Do you see Found Blocks >0 when you know you have found a block with versions 2.10.5 onward

Thanks!
 

It's the same counter used to display when you get the exit summary as is used to display it in the API.
Of course, if you zero the stats - that gets zeroed also.

Kano,
I have not zeroed the stats. I will check it out on exit when i do upgrade cgminer. I am sure that there is something wrong. Anyway, I will let you know what info i get on exit

Best

If you check the API and the Summary at the end when you exit, they will be the same.
The variable that stores the block counter is the same one both pieces of code use.

I did notice yesterday that ... 9 months ago ... ckolivas added a pool block counter that also keeps track of blocks per pool - that I've never added to the API - it's now in my ... todo list

I am the author of Bitcoin Miners in Tray, a Windows universal front-end for coin miners:
https://bitcointalk.org/index.php?topic=149442.msg1642010#msg1642010
http://stanislavs.org/bitcoin-miners-in-tray-miner-gui-manager/

When testing it with CGMiner, I discovered a bug in how CGMiner outputs lines on stdout. First of all CGMiner needs to be started with -T to disable ncurses, which is fine.

The output on stderr is also written correctly, so that the front-end gets an event after each line that is sent to stderr stream from CGMiner.

stdout, on the other hand is not flushed after each line, so that the front-end gets all text on stdout redirection in one huge chunk at the moment when CGMiner stops and closes its streams.

The only workaround is to use --verbose and read what should have been on stdout from stderr, living with that huge text dump when CGMiner stops.

Could those, who are maintaining CGMiner fix this issue, applying the same writing strategy to stdout as is done to stderr?

I run cgminer inside a GUIMiner derivative, and I haven't noticed any problems such as the one you're describing.

Try adding -l 1 (lower-case-L one) to your startup parameters.

Thanks for the tip. Specifying -l 1 starts producing a consistent output. Interestingly, giving any other value than 1 will lock output on stdout until cgminer is stopped, at which time a lot of the output is dumped to the pipe. Something is definitely wrong. Only CGMiner (and pooler's cpuminer, but in that case on stderr) display this problem. poclbm, rpcminer and phoenix seem to work fine.

Here is output with -l 2 (output from my front-end is green, stderr is red, stdout is blue):

I'm guessing you're talking about windows. Windows does random things with the logging output it seems. Gotta love its (arse)soul.

Seems like a dotNet issue, since Python on windows handles it fine.

No dotNet in the posix c code that is cgminer.

I'm saying the problem with Nemo's dotNet-based front-end is a dotNet issue, since a GUIMiner, a similar Python/Win32 front-end does not have the same problem.

Then this is inconsistent. I am only observing this issue with CGMiner and cpuminer (from which CGMiner was forked). Poclbm, rpcminer, as well as some other command-line tools, which I ran for test purposes from my front-end (like ping.exe -t) are handled just fine, with output showing just when it is expected.

[tacotime]

Does anyone else get about 5% invalids using the new cgminer and high thread concurrencies?  Gonna switch my 7950s back to reaper for now until I figure this out.

[bicer]

For some reason cgminer is "consuming" all available ports when run with '--fix-protocol' and p2pool on local machine. Not sure if one of distro updates is causing this or misconfiguration somewhere. Tried cgminer versions all the way back to 2.7.4 and Python 2.7 and 2.6.
Anyone got idea what could be the cause? Below is part of very long list of netstat -tnp

what happened with 2.11.3 log format, why is not reporting hashrate anymore ?

[flound1129]

cgminer is using about 25% cpu when mining bitcoin.. Uses 0% cpu when mining litecoin..

Is this normal?

[Fiyasko]

Nope!, I assume you have a quad core CPU? Check to see if you have the "100% cpu bug" by setting CGminer to just one core, If the one core is loaded up beyond 97%, Then you have the bug.
It might be nothing more than an SDK/Driver bug that is fixed with the newer drivers

I hope you're not using the same Intensity for both BTC and LTC. Your -I for BTC should only be like -7.

[ditchmagnet]

Has intensity for LTC been fixed yet in 7xxx cards?  I much prefer cgminer over reaper, but I cant use it with my 7950 right now.

I'm not sure what problem you're referring to, but for me, cgminer works at least as well as reaper for LTC mining.

With a GIGABYTE GV-R785OC-2GD clocked at 1150/1000, intensity 19, thread concurrency 27164, 1 gpu thread, I get pretty much the same hashrate with cgminer and reaper (~390kH/s).

I also played around with another configuration at intensity 13, thread concurrency 13632, and 2 gpu threads. With this, I get ~360kH/s in cgminer, and a hard crash requiring a reboot with reaper. With cgminer at this intensity, I *am* able to use the desktop for other purposes.

Interestingly, reaper in the first configuration uses ~1.7GB of system memory. cgminer in both configs uses ~40K...!

With my hardware, I don't see any reason to ever use reaper. YMMV with different hardware, of course.

[Proofer]

I use Catalyst 11.12 and SDK 2.5 on Ubuntu 12.04 (phatk kernel). It took me a long time to figure out how to install both of them properly. Unless you're using 7000 series cards, I'd recommend this combo.

I just upgraded from 11.04 to 12.04 and am in the throes of trying to figure out what you figured out. After about 24 hours of messing around I'm just about to re-install 12.04 to get a clean slate. Do any memories/hints/notes come to mind?

[tiberiandusk]

Since 10.5 CGMiner crashes on launch and all the versions following that. 10.4 works fine. Using Windows 7 64bit. Any ideas on what to look for?

[Proofer]

I was mining OK with Ubuntu 11.04 and Catalyst 11.06. After upgrading to Ubuntu 12.04 and Catalyst 11.12, I built the current cgminer from source, which has been my usual practice. Two problems:

1. The system is not detecting my display monitor's characteristics and is using a generic "laptop" monitor config with the wrong resolution. This is not a big problem, but I'm mentioning it here in case it's a clue.

2. cgminer 2.11.3 is not seeing my three 5970 GPUs:

Code:

proofer@prooferminer:~/miners/cgminer$ aticonfig --lsa

I'm stumped.

?
sudo aticonfig --initial -f --adapter=all

and of course the usual (which I put in here a few days ago)
To see that your display is correct:
export DISPLAY=:0
xlsfonts

[Proofer]

?
sudo aticonfig --initial -f --adapter=all

Yes, I had done that prior to the results I showed. I was following the procedure from the Unofficial Wiki for the AMD Linux Driver. I used the commands to create fglrx .deb packages from the AMD Catalyst 11.12 download and install the packages, plus aticonfig etc.

and of course the usual (which I put in here a few days ago)
To see that your display is correct:
export DISPLAY=:0
xlsfonts

That returns a long list of fonts.

EDIT: However...
