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

[cablepair]

Version 2.3.3 - April 15, 2012

Human readable summary:
- Over temperature GPUs that should have had mining suspended but did not, should now be fixed.
- Windows lusers that had the ATI Display Library fail and stop reporting fan speed, which would then cause cgminer to just abruptly stop, should now have cgminer spontaneously restart from scratch if it detects this mode of AMD failure. It is a gamble, but should work based on feedback from people that had this problem.
- There is now a restart cgminer option within cgminer.
- When mining with more than 8 devices, the display will only show a summary instead of corruption.

Full changelog:
- Don't even display that cpumining is disabled on ./configure to discourage
people from enabling it.
- Do a complete cgminer restart if the ATI Display Library fails, as it does on
windows after running for some time, when fanspeed reporting fails.
- Cache the initial arguments passed to cgminer and implement an attempted
restart option from the settings menu.
- Disable per-device status lines when there are more than 8 devices since
screen output will be corrupted, enumerating them to the log output instead at
startup.
- Reuse Vals[] array more than W[] till they're re-initialised on the second
sha256 cycle in poclbm kernel.
- Minor variable alignment in poclbm kernel.
- Make sure to disable devices with any status not being DEV_ENABLED to ensure
that thermal cutoff code works as it was setting the status to DEV_RECOVER.
- Re-initialising ADL simply made the driver fail since it is corruption over
time within the windows driver that's responsible. Revert "Attempt to
re-initialise ADL should a device that previously reported fanspeed stops
reporting it."
- Microoptimise poclbm kernel by ordering Val variables according to usage
frequency.

Windows lusers

my only question is did you intend to call them Windows Lusers? hahaha

I must have broken it when I instituted the REST followed by restart if it detected overheat. Unless of course it overheated, cooled enough and then restarted over and over again in short bursts? Was it submitting shares at the same rate?

No, it never stops, shares are submitted with same speed at same temp. I've tested identical config with 2.2.1 and it worked without any issues.

Okay thanks. I have reviewed the code in question and indeed it would not cut out. I have fixed this bug in the current git tree.

Thanks! Working now. There's another issue tho - I can't change voltage for 6870 in cgminer, for 5770 its working fine. This is the only one issue which stops me from moving to linux.
 Btw it's possible to integrate similiar overclocking system as in ati tray tools, so it will be possible to underclock memory to 300 mhz and lower with cgminer for 6xxx series? Maybe ATT dev using some simple trick for it.

No, they're the limits of software manipulation without device specific hacks that are only available to certain vendors (i.e. not me).

Any other linux apps then which can undervolt it?  

 Maybe just ask Ray Adams (ATT developer) how he did it? It's actually pretty funny that ATT is the only one app that can underclock memory of 6xxx series to 300 mhz or lower. Something is plain wrong here. Eh, maybe because he's russian?

Hi ckolivas,

a few weeks back I ran into some communication failures and high reject numbers at BTCGuild after a LP-change

I escalated the problem to Eleuthria https://bitcointalk.org/index.php?topic=49417.msg839599#msg839599 and he said he would contact you about it

Apparently the problem doesn't come up with everyone just with low-latency miners and pools with Poolservj running

I'm running into the same problems with Clipse's pool but have NO problems when mining on Deepbit for instance (tried out a lot of different pools in the last few days)

I submitted CGMiner output on BTCGuild here https://bitcointalk.org/index.php?topic=49417.msg839444#msg839444

and this is the output from Clipse's pool

Code:

In other words it uses windows only tricks that won't work on linux. Eventually you will come to the same endpoint that everyone does when asking this same question of me, and so I will have to add this to the FAQ from now on.

There are limits to what overclocking features will work within cgminer as it uses the ATI display library to do the overclocking. While cgminer will allow you to set values outside the bios limits, it does not mean they will work. Some cards will allow it, others will only allow it after a bios flash, and the rest will either reject the value or silently ignore it and pretend it worked. Other tricks that bypass the driver and poke the cards directly will not work in cgminer, and will not be usable in a portable cross platform software way.

This appears to be only related to pools that run that java pool software. Why, I have absolutely no idea, unless you are having runs of packets that confuse routing somewhere along your line since it dies for something like a minute. Try the --net-delay option. Yes I know you have a fast and close connection, but that doesn't change the fact that some routing points, be they your network, the ISP, some random router between you and the pool, or the pool itself, can do weird shit.

[DutchBrat]

Thanks for the suggestion,

I'll give it a try

Is there any news on ztex support? (If it's actually planned)

[nelisky]

Is there any news on ztex support? (If it's actually planned)

ztex is supported on my branch https://github.com/nelisky/cgminer/tree/ztex but:

- hotplug support, while working is based on a "hack" to cgminer and will not yet be pushed to the main cgminer, if ever.
- you can use my code right now, but it has not been verified by ckolivas. I am in the process of splitting ztex support / hotplug support so I can make a pull request for the former, which will happen very soon.

[Chefnet]

that will be fine, and do you want to insert the quad support too?

[nelisky]

"Are you talkin' to me?"

Yes, I've already asked for details on what changes in the API, and will have a look at BTCMiner sources as soon as I can get my hands on them. While I don't plan to own these quads soon, I do want cgminer to have the best possible ztex hardware support.

Okay, I'm going to need you to go ahead and rewrite the ATI linux drivers, m'kay.  There is a nice shiny bitcoin in it for you.

Hi folks,

Sorry for cross-posting, but I figured folks watching this thread would be interested.

I just released the first version of a Cacti template for monitoring CGMINER (Summary, Devices and Pools are supported). Details and more sample graphs are available here.

Here are a few teaser graphs:

 Total Average Hash Rate (from MHS av)


Total Hash Rate (computed from Total MH)


Total Utility


Total Work


Total Efficiency (computed from Accepted and Getworks)


Total Errors

On the side;

I'm beginning to believe that that any form of communication can be reduced to a meme at this point.
