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

[ancow]

The last couple of commits fixed these, thanks.

[-ck]

Thank you for the bug reports

[-ck]

New version: 2.0.5   Links in top post. The linux binary archive also includes a cpuonly binary.

- Intensity can now be set to dynamic or static values per-device.
- New donation feature --donation sends a proportion of shares to author's
account of choice, but is disabled by default!
- The hash being displayed and block detection has been fixed.
- Devices not being mined on will not attempt to be ADL managed.
- Intensity is now displayed per GPU device.
- Make longpoll attempt to restart as often as opt_retries specifies.
- We weren't rolling work as often as we could.
- Correct some memory management issues.
- Build fixes.
- Don't mess with GPUs if we don't have them.

I just installed 2.0.5 from git, running smoothly as always.

I guess that I will start the features-for-donations requests:

1)  The ability to pause/unpause mining.  Ideally this would be easily done by another program (without sending keystrokes).  I am thinking perhaps a SIGINT or SIGCONT could stop and start mining respectively. 

I recently switched to hourly based electricity pricing and plan on evaluating the feasibility of mining every hour.  That is what inspires this request to be able to pause mining during peak electricity demand. 

Thoughts?

SIGSTOP/SIGCONT don't work?

Perhaps my limited knowledge of signals misinterpreted them.  I thought that it was up to the program to choose what to do when they got those.  Perhaps the are the wrong mechanisms for communicating with the process.  I am running cgminer in screen, if it receives SIGSTOP, screen (I believe) restarts it.

There already is a time based scheduling option. I suspect that suits your purpose?

--sched-start <arg> Set a time of day in HH:MM to start mining (a once off without a stop time)                                                                                 
--sched-stop <arg>  Set a time of day in HH:MM to stop mining (will quit without a start time)

I was actually planning on evaluating my profitability every hour since my electricity prices are updated every hour.  Therefore it would be more of a game-time decision if I want to mine or not. 

Obviously I could just kill/start cgminer.   But I was thinking that a pause feature would be nice, but it sounds like communicating with cgminer once it has started might not be as simple.

a pause feature may not be that good.
it is posible that by the time you resume the miner anything it has queued would be stale anyways.

You can currently pause one device at a time from the Gpu settings menu. If you pause it and the work goes stale, it's no big deal as cgminer just throws out stale work and grabs fresh work. Cgminer goes to extreme lengths to avoid working on, or submitting, stale work.

Would love to see the Changelog in the first post. Otherwise I have to search the forum for each changelog..

Um, the reply question is missing the facts about shares/blocks
Do you mean evaluating it based on results? Then of course the results are:

The number of shares/blocks you get per hour does not depend on anything but statistics and the number you will get is an expected statistical average.

There is no reason to adjust your mining based on results - it's simply a case of calculating the average expected number of shares per hour.

That is a simple calculation - if your rig calculates 700Mh/s (as an example) then you will get a share on average every 2^32/(700*10^6) seconds.
Or if your hash rate is a high Z GHash/s then you will get (Z*10^9)/(2^32) shares per second (the inverse of the previous calculation)

Turning that into hours: If your hash rate is Z GHash/s the number of shares per hour:
(60 * 60) * (Z * 10^9) / (2^32)

of course if it is Y MHash/s then it is (60 * 60) * (Y * 10^6) / (2^32) shares per hour.

Again, this is the average statistical expected result.
Nothing can effect the actual result you get other than your hash rate and the reliability of submitting shares.
cgminer is really good at both of those

Yes..but a changelog shows if it's worth to (download&)update 4 machines or wait for the next release

Hi! Could you please help me. I am looking forward to run cgminer but I can properly configure it.

Please post the right settings for me.

THANX

I need my rig to switch to the 2nd pool if the 1st is down. I have 4 GPUs. The 3rd one ( device 2) is used for descktop. The also have different mem and core clocks.

Is it possible to configure cgminer to satisfy all these demands?

Yes it is. I can't guess what settings you want for mem and core clocks, but assuming mc0 is the memory clock for GPU 0 and ec0 is the engine clock for GPU 0, something like this:

cgminer -o url1:port -u user1 -p pass1 -o url2:port -u user2 -p pass2 -I 9,9,d,9 --gpu-memclock mc0,mc1,mc2,mc3 --gpu-engine ec0,ec1,ec2,ec3 --auto-fan

[RedLine888]

cgminer -o url1:port -u user1 -p pass1 -o url2:port -u user2 -p pass2 -I 9,9,d,9 --gpu-memclock mc0,mc1,mc2,mc3 --gpu-engine ec0,ec1,ec2,ec3 --auto-fan

Cool! THANX a lot.

How should it look like with custom fan settings for each card?

I noticed that only one username and pass is used. Does it mean that the power of all 4 cards will be assigned to 1 pool worker?

This!
I have been trying to assign a worker account to each worker. Is it possible?
This only makes all GPU for a single worker:

cgminer -o http://api.bitcoin.cz:8331 -u user -p pass -w 256 -v 2 -I 8 -d 0 -o http://api.bitcoin.cz:8331 -u user2 -p pass2 -w 256 -v 2 -I 8 -d 1 -o http://api.bitcoin.cz:8331 -u user3 -p pass3 -w 256 -v 2 -I 8 -d 2 -o http://api.bitcoin.cz:8331 -u user4 -p pass4 -w 256 -v 2 -I 8 -d 3

[-ck]

No. Run separate instances if you want that.

failed to init GPU thread 1, disabling device 1

What is wrong?
