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

Hi,

I understand that scrypt/GPU mining support was removed from cgminer. Still I think this would be the best place/resource to help me in understanding the following.

using cgminer 3.7.2 some people experience the following error
" error -4: enqueueing kernel onto command queue "

what exactly does it mean?

Mining on R9 290 hardware
people have noticed, that higher TC values can cause this;
also using less than 8GB RAM can cause this.

Any insight what this error means exactly?

I see this when the driver crashes.  I'm running 3.7.2 on a good number of 280x GPUs, two of which have 4 gb of memory on win7 x64.

Check the litecoin wiki page for recommended settings for your card.

but the driver does not crash. using 4GB ram causes that error with high TC, using 8GB ram and everything is fine (or lowering TC).
I am trying to find out if this is a bug in cgminer that somehow requires PC-RAM...

what exactly does that error mean?

I think it relates to the driver.  Wish I could help you more.

ckolivas...I'm just being curious/nosey here, but is there an amount of BTC you have in mind that would bring back GPU mining support in cgminer?  heh..  

While I have your attention I also wanted to ask if there is a scrypt specific fork of cgminer that you might recommend to people that want continued GPU development.  The GPU questions seem to be coming more and more often as of late.  I've tried a couple of the forks, but I'd love to hear if there was a particular developer you worked with on the hand off that stuck out from the rest.  I really expected someone to be leading the pack on scrypt mining by now, but nothing just jumps out at me.  I was wondering if maybe I wasn't looking in the right places.  I'm not really sure where I would direct people with GPU questions these days...or myself for that matter.  heh..

I know you don't want to be bothered with GPU questions anymore.  Putting a specific fork of the code in the limelight would probably steer a lot of the questions in that direction.

Thanks!

I originally wrote the scrypt code for cgminer for 100BTC, which was my "I don't want to do it" price back then. I wish I had said 1000BTC instead. That should give you some idea.

I pay no attention whatsoever to forks or gpu or scrypt code so I have no idea nor can recommend anything.

I know you don't mean it, but this is unintentionally flamebait. All my responses about GPUs/scrypt/litecoin do is piss people off more since they can't accept I have no interest in them and then they resort to personal attacks.

I actually thought about sending you a PM for a fork recommendation instead of posting the question because I know how people like to start internet wars.  My heart was in the right place...I know you're sick of all the GPU questions coming in.  

Right now I foresee two scenarios.  A)  Someone steps up and support gathers around a fork.  B)  Some rich Good Samaritan/fool lays out enough coin to drag you back in like The Godfather movies.  lol

If you've got an Nvidia card, will be worth your while hitting up the Cudaminer program in the altcoins section, written by cbuchner1. It's forked from CPUMiner, but he's put some solid work into it for almost a year now and it's making the cards punch above their weight a fair bit with regards to Scrypt mining, but not quite as much as the AMD cards. It wouldn't be too much of a stretch for someone to develop an AMD-dedicated version to better take advantage of them compared to a catch-all program.

That said, would love to be able to merge the relevant code from Cudaminer into a fork of CGMiner to be able to monitor the cards and switch pools more easily, but I have a very, very basic understanding of C. Could do it, but it would take a fair bit of time (i.e. months) for me to learn and try to do it.

Downloaded and am running 3.8.1 on Windows XP. I chose 3.8.1 because it's also the version on my rPi.

Anyway, I got the config file set and it seems to run ok and says waiting for devices. However, when I plug in onee of my ASIC 333Mh/s devices I get this.

 [2013-12-26 17:31:03] USB init, open device failed, err -12, you need to install a WinUSB driver for - AMU device 2:1
 [2013-12-26 17:31:03] Icarus detect (2:1) failed to initialise (incorrect device?)

Anyone able to help me et this working on the laptop ? I ask because my rPi is gonna be MIA for a while so I need to get CGMiner goin on the laptop.

when or how can we have support for nanofury usb erupter with cgminer? Is the only programme that can work without problems under linux but it didnt support nanofury usb and i cant use it because i have some of them

you cant use a driver from bfgminer or to ask to sent you?

See:

However, they are sending me one, so a driver will be written for it eventually.

[chek2fire]

thank you i will wait for the support and i like to say a gz for your programme.

I've been using igpu for display and 270x for mining but display is still laggy and comp nearly unusable,
what could be the problem?

[nov]

Could somebody tell me what does mean and what to do, if I see this message in CGMINER, please?

BlackArrowBitFuryGPIO failed open /dev/mem (13)

I am using Butterflylabs Little Single SC.

Please who can give me a command line, I put two Asicminer erupter usb on COM3 and COM4, I took cgminer 3.1.1 but still can not make it go .... the miningpool adress is miningpool.nl:8332

Just use the Zadig utility to install the WinUSB Driver and run the latest CGMiner with no command line options, besides your pool info.  Easy Peasy.

Edit: Provided your using Windoze.  If not you can forget about the Zadig/WinUSB part altogether.

There is a patch with a driver available:
https://bitcointalk.org/index.php?topic=321287.msg4086475#msg4086475

For me it works a lot better than bfgminer.
