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

[-ck]

Hi guys,

Bit of an issue, not serious. Cgminer is showing 30% cpu usage since upgrading to latest - seems very high eh? I done the usual compile with make clean, had no errors at all that I could see, it just seems to be a bit too heavy on resources - any suggestions? Xubuntu 12.04 64bit.

That does sound wrong. Did you set CFLAGS to enable optimisations? I see 1% CPU usage on a modern CPU with 217GH across 4 devices on a similar linux.

Hi ckolivas,

Here's what I used to compile:

./autogen.sh
make clean
CFLAGS="-O2 -Wall -march=native" ./configure --disable-opencl
make

Is that right? I know it's a new, different build.....It's running 40 USB erupters.

Edit: AMD Phenom X4 9750  4GB Ram on a ssd.

Edit2: Just done another git pull - couple of minor additions, rebooting & trying again.......

Maybe I am wrong, because I dont know nearly as much as even a novice user, but, shouldnt the "make clean" line come before the CFLAGS line?

I don't remember why, and I can't find a post saying why, but I'm still running 3.1.1.  I decided to try out 3.4.2 and I get this:

Code:

ADL..................: SDK NOT found, GPU monitoring support DISABLED

from the exact same configure command I can still run in the 3.1.1 source and get this:

Code:

ADL..................: SDK found, GPU monitoring support enabled

.  Any chance a change needs made in the source to fix that again?  I know this happened once before and it was a pretty quick fix, after which I redownloaded.

Typo corrected.....   Ta.

Right, I'm obviously done something wrong here. Rebooted & now got the "all devices disabled - cannot mine" death sentence.

What you reckon - uninstall/reinstall everything? or is it a simple fix?

I'm such a nonce sometimes.......

[SoulSlayerPT]

"Do not use on multiple block chains at the same time!"

So, the thing is.. Does not work?... Dam.. Can't i just disable the get blocks from another pools and it only runs from the pool 0 and get blocks from it?

Read about how pooled mining work...

Sorry, what do you mean? Did you understood what i am asking? I am trying to solomine a coin and have a pool from other coin in the same config. So i just switch pool when i want and i don't have to close cgminer. I just wanted to cgminer to use one pool and disable all the rest unless i select the pool.

As long as all of the pools/coin daemons in your config are using the same blockchain, there is no harm in allowing cgminer to detect block changes from a pool while solo-mining.

Then why don't you disable them?  [P]ool  [D]isable  

You know, there's useful information in the readme down past line #3...

It wouldnt hurt, if you have that time.  I would start over, download the latest version from the git and extract, then move your "make clean" line before your ./autogen.sh line, recompile and see if that works.  Again, I know less than you do, just from the little bit I have seen around and from what I have done, it seems you have to make clean first, I almost think that when you do the make clean after your CFLAGS line its wiping our those options you just enabled.

OK, reinstalled everything - no go:

" [2013-09-04 18:21:42] Started cgminer 3.4.2
 [2013-09-04 18:21:42] Loaded configuration file /home/bitcoin/.cgminer/cgminer.
conf
 [2013-09-04 18:21:42] All devices disabled, cannot mine!"

Seems it's not detecting my usb? Also seing this at end of report:

"configure: error: No mining configured in"

Any help would be greatly appreciated......

AH, stupid me, you have to enable your USB's as well.  So, you arent wanting to use your GPU's at all, right?  Then in addition to --disable-opencl, you need to also include --enable-blfsc --enable-icarus --enable-avalon

This will enable block erupters, butterfly lab USB devices, and Avalon devices.

...
CFLAGS="-O2 -Wall -march=native" ./configure --disable-opencl
...

Lulz - you do actually have to compile in a driver or 2 ... otherwise without a driver ... it wont find any devices.

CFLAGS="-O2 -Wall" ./configure --disable-opencl --enable-icarus

To see that the driver you want .... isn't there
./cgminer -h | head -2

After you actually include at least one driver
./cgminer -n

Edit: lol OK someone just posted that before me ... I was slow typing

[PatMan]

Aaah, don't say that! You make me sound stupider than I actually am.......

Right, let me go at it again.........

Kano & Zanatoss666 - Thanks. I am putting myself forward as main candidate for "CGM shit-for-brains award 2013".  My stupidity amazes even me sometimes......

Right, now that I've done embarrassing myself, I'm still stuck with this 30% cpu usage problem - any ideas on that one?

Be gentle with me.......

That is a good idea! Thank you!

Nice would be a way of if i change to a pool disabling the rest!

You really shouldn't mix and match different blockchains in the same config, or in the same session.  It's really better to have two config files, quit out of cgminer, switch the files and restart.  You are just asking for trouble trying to switch between them on the fly.  There are reasons why the instuctions specifically say not to do this...

I don't remember why, and I can't find a post saying why, but I'm still running 3.1.1.  I decided to try out 3.4.2 and I get this:

Code:

ADL..................: SDK NOT found, GPU monitoring support DISABLED

from the exact same configure command I can still run in the 3.1.1 source and get this:

Code:

ADL..................: SDK found, GPU monitoring support enabled

.  Any chance a change needs made in the source to fix that again?  I know this happened once before and it was a pretty quick fix, after which I redownloaded.

Copy the ADL_SDK include files from 3.1.1 (or the sdk_app thingy) to the ADL_SDK directory and re-configure.

Duh!  Been way too long.  Thanks.
ETA: Sent a bitcent your way.

Using 3.4.2, logging to syslog.

If my cgminer log interval is not set to 5, I don't receive the log entries like

Code:

(5s):xxG (avg):xxGh/s | A:xx  R:xx HW:xx  WU:xx/m

to syslog at all. I still get other syslog entries from cgminer, just not this entry. When log interval is equal to 5, I get that entry every 5 seconds.
