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

A quick question: how do I instruct cgminer to use only GPU and ignore all USBs?

A quick question: how do I instruct cgminer to use only GPU and ignore all USBs?

The README says that "--usb :0 will disable all USB I/O other than to initialise libusb".

[Nemo1024]

Thank you, and excuse my laziness.

Any idea how/why this happens?



The software works like a dream... and I love you for it.... so please don't take this as a complaint, just as a "I wonder if I'm using it incorrectly".

The GPS are hashing like MF'ers, and blocks fall before me... so why does it tell me 0% load?

cgminer only reports back whatever the driver tells it the load is. However the driver will report 0 if you query it too often. I don't know what front end you're using there to communicate with cgminer but perhaps that's all it is.

BAMT and the mgpumon tool.

Good to know.  Thanks.

Thanks, Kano. Let me get my rpi and program it very thanks for the sharing of the setup! And I gotta buy that cute USB LCD!

With 3.4.0 do you still suggest arch is better option? Or both are the same?

I'm not sure why Minepeon has had trouble on Arch - so I don't know.
The original libusb problem didn't exist on Arch with that install I've used, but there is of course a simple workaround for Raspbian - use the libusb in the README (which I now use in all my binary builds)
I have had the rare network dropout occur on both Arch and Raspbian
At this point I'm using Arch for mining and Raspbian is the media player ... that's incomplete.
However I'll probably put an AMU in the media player soon just so it's running cgminer all the time rather than just testing when I build my binaries

Hi,

I was having a lot of messages in cgminer  "BTB: Idled X miners". When that happen my hash rate would go down by half. 3.4.0 resolved all the issues Great job guys! Thanks.

If you can build from git and you're on OSX, try building now as I've added a generic workaround for this.

Cool!  Thanks for doing this.  I get this when compiling now:

Code:

util.c: In function ‘cgtimer_time’:
util.c:1017: error: ‘ts’ undeclared (first use in this function)

Thanks. git pull and try again please (I'm coding blind!)

If I could buy you a Mac to help you test I would, but thanks for this nonetheless!  I built from the latest git and it errored with:

Code:

ld: library not found for -lrt
collect2: ld returned 1 exit status
make[1]: *** [cgminer] Error 1
make: *** [install-recursive] Error 1

If you are interested in the entire compiling output, it produces a few Mac-specific warnings that don't seem to affect the program (these warnings have existed for a few versions now):

Perfect, that did it, and thank you!  I just sent you a very tiny bitcoin tip.  Don't even look at the value, seriously, it's so tiny (that's not sarcasm either).  But hey, good work should be recognized.

You're solo mining. Only a block solve would get accepted.

But in the earlier version was all good...

[gal40n0k]

I have to go back to the previous version?

Solo mining with GPU?      Did someone fall asleep for 2 years?

I've been mining alternate coins. Someone will answer my question seriously or is there only one clown?

Unless something changed far more recent then that mining using scrypt should still be profitable. I don't mine scrypt so I don't know for sure.

I don't know for sure but if your difficulty provided by your alt-coin wallet wasn't detected properly then you would submit shares and they would be less then a block. I wouldn't think you had that many close to a block since the last version was posted. I am guessing as I have dealt with neither. Likely someone knowledgeable will have a better idea.

As far as the facts go though just watch hopefully a block level difficulty share will come up and you can see if its being rejected. Oh and check your CGMiner difficulty against if there is a source for diffictulty like blockchaininfo for bitcoins.

The scrypt and GPU mining code is unchanged now for 6 months+. Likely you have changed something else.

Yikes, I'm about to look into getting cgminer or something to mine all the coins that CGWatcher supports with it's profitability calculator, sounds like I'll be running into a whole world of pain if some of them require more exotic settings.  Why do I do this to myself?  Ah the fun of tinkering, he he.
