Topic: OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.0 - page 19. (Read 5805312 times)

Ok, with cgminer-4.9.2, my AU3 (https://www.amazon.com/gp/product/B016CWBYJK/) gets 12.5Gh/s over several days.  With cgminer-4.10.0, it gets 8.5Gh/s over several days.  The older USB miners all get the same on both versions.  Both versions have all generic USB drivers enabled.  I get the same results on both my 256M arm controller and an x86_64 desktop running Fedora 25.  I'm also getting a lot more accepted hashes with 4.9.2 - several times more, which the modest increase in total hashing power doesn't explain.  [^1]

Conclusion: There may be a (subtle and hard to debug) problem with 4.10.0.  :-(

I will try to submit this to Fedora as an official package.  Fedora will ship using the system jansson lib.  4.9.2 autoconfig is unable to find the system jansson lib, but 4.10.0 does find it.  

Another question:

When systemd kills cgminer (either version) on the ARM system, cgminer spits out a summary as it shuts down which goes into the system journal.  Nice.  When systemd kills cgminer on the x86_64 desktop, cgminer just dies.  No summary.  No "shutting down" message.  Why?

[1]: over a 3 hour period, my tiny rig got 9 accepted shares, with a square root of 3.  So the changes in accepted work units are within reasonable variance for such a small rig.

The source for 4.10.0 helpfully provides api-example.php which shows raw summary data, and then php data structure parsed from the raw summary data.  All good, and works.

So, not being a php person I attempted to boil down what api-example.php does, and akaict it does this:

$ echo -n summary | nc 127.0.0.1 4028

Silly me, not only does that not work, but it crashes cgminer, and my 256M arm system running cgminer.  (Some sort of resource exhaustion - system is still pingable, but unable to accept new logins.)  Apparently, the slow readline loop to read result bytes one at a time is critical to avoid crashing cgminer.  Is this a known problem?

All I want to do is monitor the total hash rate with nagios.  I guess I can run php at each check...

I tried this on a x86_64 desktop (Fedora 25) running cgminer-4.10.0, and it works. On the arm controller, both versions crash with "echo -n summary | nc 127.0.0.1 4028".  So I guess it might be a timing thing, and that slow read loop is critical on tiny computers.  Maybe I can simulate it with python.

I tried with and without the embedded jansson-2.9 lib on X86_64 - it works on both.   The arm box system jansson is 2.6, so I used the embedded version.
----
Update: twice now, reading status via API from miner.php has crashed the arm controller.  So it is a timing thing, and it just happens much less often with the php client.  The next step will be to put some resource limits on cgminer via its systemd service.  If I can keep a login running when cgminer crashes, then we can do some debugging.

Post in the altcoin section, you should get plenty of help there.  This is the Bitcoin section.

Thanks ck. Is there any other trusted miner through which I can mine using intel graphics or even a separate graphics card. I am not looking to mine Bitcoin, but scrypt based altcoins.

No.

Bitcoin is mined with dedicated hardware called ASICs these days ONLY and not regular PC hardware, and this software is only used to drive ASICs.

Hello guys
I just wanted to know if this would work on intel i5-4440 graphics. I don't have external graphics card, but 1 GB of memory is reserved for intel graphics. I am totally new to mining. I hope you guys will help me.

This would be the rework based on Novak's code, for proper base compac support in cgminer.   

More recent code will be a complete ground up design / approach for the new products with backward compatibility.   
It has a side effect of nicer performance for the original compac, but is not ready for main cgminer yet.

The pull request looks to be VH's code.

Is Compac support based on Novak's Icarus rework from 2015 or so, or VH's new code from the last couple months?

You're welcome. Since I don't have one I'm relying entirely on the assurance from the code submitter that it actually works. All I could do was confirm it didn't interfere with existing similar devices that I own.

glad to have compac support baked in now. thanks!

will be nice to have the official cgminer running again.

EDIT: avast thinks its a virus. naturally 

will send it in to them so they can white list it.

Anyone have a good working link for a compiled binary for cgminer ubuntu 386/32 build or one that will work on that?
I did get one from https://launchpad.net/ubuntu/vivid/i386/cgminer but my system didn't have permission to install it. 

Thanks all for the help, will pm.

Batch files are meant only for DOS, never for unix.
For unix you need shell scripts.
I might help you writing one (and you'll also learn how to navigate in unix, edit files and execute them) if you PM me what you want to achieve.

Windows text files usually have windows end of line markers which aren't normally readable as text files in unix. Try converting them to unix files
dos2unix file.txt

Additionally if your batch file contains windows dos commands it will never work...

I'm new again to using a Linux machine, only really having a lot of telnet Unix experience.  I installed cgminer on a Ubuntu install and copied over my Windows bat files to run.  But when I click on them I get the four options to run in terminal, display, cancel and run.  None of them seems to be working on batch files I've used for several months for Windows cgminer.

No, You can only mine Bitcoin on dedicated ASIC Bitcoin mining hardware now.  And this isn't the correct thread for that question.

can I mine on my laptop?

Yes that's correct. In the file ASIC-README it lists the avalon4 specific commands, they're the ones starting with --avalon4-*
