OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.10.0

[jedimstr]

The last cgminer version doesn't support scrypt anymore. Is there a fork somewhere adding back the opencl support, and updating the software?

Scrypt oriented Forks are being discussed on the Litecoin forms. I believe Wolf has his initial pass available for testing. https://forum.litecoin.net/index.php/topic,6994.0.html

Configured autostart works this way.

-We need to edit autostart with this command: sudo nano /etc/xdg/lxsession/LXDE/autostart
-At the end add the line: @/usr/bin/lxterminal --geometry=90x35 -e cgminer (The parameter "geometry" is to set the size of CGMiner, so adjust the parameter to your needs)

Then if I remove power cord from Raspberry PI and Butterfly device, simulating problem with electricity.
Then after put power cord back and reboot, the "USB device in use" is displayed in CGMiner.

And I need to remotely login with TightVNC to Rasperry PI and remove the file /tmp/cgminer-usb-1-4 to allow CGMiner access to the connected Butterfly USB device.
Then CGMiner finds and uses the device.


This issue prevents auto start to work properly, since delete of the file is needed.

I tried even to try autodelete such file prior start of the CGMiner, during reboot.

But it somehow did not help.

I am currently using Minepeon distro and CGMiner there.

There seems not to be the observed issue.

Thank you for the update.

Do you think this version should help with my USB device in use issue?

I use Raspberry PI and ASIC Butterfly 30 GHs.

I have configured auto start of cgminer 3.8.2, which works perfectly.

But it always reports "USB device in use" type of message, if I remove power cord and put it back in this case. (My test of auto recovery.)
I need to manually delete /tmp/cgminer-usb-1-4 file then to cgminer be able to access the ASIC USB device.

Could you advice how to automate process the way that the cgminer will always have access to USB device?

It's supposed to be automated... Seems to be that the restart never works on these devices. Only quit followed by starting cgminer again does. Are you using the restart command or doing quit followed by starting it again?

That sounds suspiciously like you actually have 2 cgminers running at once without knowing it. The file is a red herring by the way and not the actual problem.

Started the test of cgminer-3.8.3 at 13:57. First zombie (AMU20) appeared briefly at 14:05 but it auto-started working again as AMU34.  Two more zombies appeared at 14:12 and 14:24 (AMU10 and AMU13) and they did not recover.

I stopped the test at 14:49 as there didn't seem to be much point in continuing.  The previous run of 3.5.1 was rock-solid for 13 hours, and I've included a screenshot of it at the top of logfile-3.8.3.  All looks well with that run to me - no anomalies.  Unfortunately I didn't manage to produce a screenshot of 3.8.3 before stopping it as the CMD window seemed to be continually refreshing and it wouldn't "hold" a selection to enable copying.

Logfile is here (without --debug):
  https://dl.dropboxusercontent.com/u/44240170/logfile-3.8.3.txt

Back to 3.5.1 for the time being then...

Thanks for that. Here is your next test please

I am using minepeon (cgminer3.6.4) with a Jalapeno and observing that DAcc (Difficulty Accepted) is 60-85% when mining with the eligius pool and 100-105% when mining with BTCguild. (both pools had min difficulty set to auto, but even when I changed BTCguild to 8+GH/s, the difference in percentage roughly stayed the same)
Can someone elaborate a bit on the Dacc calculation and the difference I am observing between the two pools, does it affect my share contribution accordingly???
I checked github, but I was a bit lost. I also asked at the minepeon forum but the dev just parsed the DAcc value and could not elaborate on the calculation method.

Thank you in advance

OK, Started the next test of cgminer-rst at 16:46.  First zombie (AMU11) at 21:07 after about 5 hours.  Test stopped at 21:31.  Note that the previous run of 3.5.1 ran for about 16 hours, again with no apparent flaws. Final status included at the start of the "rst" logfile for reference.  I am not logging runs of 3.5.1 but can do if it would reveal anything useful for comparison.

Next started cgminer-fff at 21:35. First zombie appeared at 22:10. Test stopped at 22:13.

Can you try fff again and this time when it gets into the loop of errors, enable debug in the display menu and continue logging for a bit please?

Why are there two bitcoin addresses?  Which one do I send a (small) donation to?  When I get "over the size limit", do I always need to pay the transaction fee, or does waiting a while also work?  UPDATE: waiting a while works.  I sent to the 15qS... address - hope that is correct.

I like to keep track of whether donations are from the source code or from the forum, thanks! Whether you should send a transaction fee or not is determined entirely by bitcoind. If you choose not to, it can take ages to go through or potentially may never do so.

OK, done.  Aside: The previous overnight run of 3.5.1 went for 14 hours, no faults.

Started cgminer-fff again.  After about 3 hours I got several LEDs full on for a few seconds. Two of them went out and resumed mining but the 3rd appeared in the display as a zombie.  I was sitting next to the PC at the time, so turned on debug straight away.  I left it running for a further 5 minutes then stopped it.

Logfile here, but I suspect it's not going to help:

And...... Back to 3.5.1 again :/

This from 3.8.3 may give a clue:

It revives the zombies until it runs out of file descriptors on unix.  Maybe some similar resource exhaustion is happening on Windows?

Interesting thought. It's easy enough to raise the number of file descriptors allowed in unix, but the default on windows should be much higher. Either way we should be removing the semaphores when the devices get zombied so that's at least one fix worth adding, thanks.

EDIT: Checked the code and the semaphores are being removed so that's not it.

Have I asked in the wrong thread? :-)
Please advise if so...

DA is the value in 1diff of all shares accepted.
If you submit 10 50diff shares and all are accepted then DA would be 500

I've no idea what you mean those % numbers are.

Thanks very much for that. Believe it or not I am (very slowly) making progress.

Here's the next test please:
http://ck.kolivas.org/apps/cgminer/temp/cgminer-ffs.exe

[Amph]

are vga still supported?

and why i can't copy past anymore with cgminer?

[os2sam]

are vga still supported?

New release: Version 3.8.1, 10th November 2013

GPU mining in any form is gone. Long live GPU mining (see previous post). New hardware support in this release and massive change with removal of GPU mining, but only bugfixes to the remainder of the code so to existing users this should be a safe upgrade, in keeping with even number releases sounding more stable.

[Amph]

yeah, i searched for it after my post

http://ck.kolivas.org/apps/cgminer/temp/cgminer-ffs.exe

OK, tested!  Aside [again] The previous run of 3.5.1 lasted 25 hours without problems, although I do remember seeing a few AMU LEDs come on yesterday for a couple of seconds and I noticed some messages which were something like the following (completely from memory, as no logging enabled, can't remember the exact mS timings):
  [2013-11-xx xx:xx:xx] TIMEOUT AMUx something took xxx mS, was xxx mS
  [2013-11-xx xx:xx:xx] TIMEOUT AMUy something took xxx mS, was xxx mS
The above disturbances didn't cause any problems, so it may just be normal network problems, but I haven't noticed them before, so perhaps it's important, perhaps not.

Anyway, the test of cgminer-ffs ran for almost 2 hours, then a zombie appeared.  I turned on debug from the display and let run for a further 5 minutes, then stopped it.

Logfile is here:

And.... back to 3.5.1 for the evening!

Thanks for that. No you were getting the timer overruns previously as well. I saw them on your successful logging when you put it up so even when it's "fine" it's not entirely fine, it's just that it sort of recovers.

Next!
