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

[Luke-Jr]

6,Reporting temperature/safety measurements can allows cgminer to shut off the FPGA if it gets too hot.

6 needs additional hardware, but we notice that the normal error rate is less than 0.1%, if the error rate goes high, that means something goes wrong.

But by then, it's too late (and the FPGA destroyed), right?

is there any reference docs about "noncerange extension" feature? 

https://en.bitcoin.it/wiki/Getwork#noncerange

It occurs to me that I'm not really aware of how FPGAs handle SHA256 internally; if it doesn't use the normal uint32-based algorithm, it might not be practical to implement.

[BCMan]

Do I need to enable engine clock autotune for "temp-cutoff" activation? Or it's active by default?

You need to enable --auto-gpu .However if you dont give it a range for engine clock speeds, it won't adjust any clock speeds, but it will still cut off the device if it hits the --temp-cutoff threshold.

Great, thanks!

I've got an issue that I hope someone can offer some help with.
I am unable to restart a GPU manually after it has been declared SICK. After changing the core voltage/clock to something (presumably) more stable, I can't restart the GPU.
If I try to enable it I am told that I must restart it first. If I try to restart it cgminer says "Thread x no longer exists":

GPU 1 is the sick GPU. GPU 0 is fine.

If I restart cgminer, GPU 0 starts up without problems.

If I restart cgminer, GPU 0 starts up without problems.

count your blessings...  once I have a dead one, i have to reboot to get it back.

[DeathAndTaxes]

Ok, I'm running 2.1 SDK now, but most of gpu stats (like temp, clocks, voltage, etc)  isn't showing in gpu menu.  However yesterday with 2.1.2 and 2.5 it worked fine. Using  2.2.0 now.

 UPD: oops, looks, like missing "[C]hange settings" option in 2.2.0.

That happens when cgminer doesn't detect ADL support.  For me it happens when using remote desktop.   The change in driver version is likely coincidental.  cgminer makes changes to cards and gets "stats" via ADL.

Are you accessing the rig remotely?  If not try a reboot and use cgminer before anything else.  I have seen AMD ADL driver? service? crash and that causes those options to "disapear".

[rcocchiararo]

hi

2 questions:

1) Any chance version 2.2.0 might be slower on single or dual (crosfire) 5830 ?

2) Any chance older cgminer versions restored not only fans, but clocks (or at least memory clock) of each card when pressing "q" ? i lower my memory to 300, but today i noticed it remains at 300 and never goes up. (Geeks3D GPU Caps Viewer detects max memory clock as 300 also).

EDIT: i just noticed that my linux box still running whatever drivers i installed on it when i built it, and SDK 2.4 still produces 300+ mhash with cgminer, meanwhile, my linux pcs are down to 280 or so. I did some reading and found out that the newer SDKs (2.6+) had that effect (starting from drivers 11.12). Even after fully removing 11.12 and installing 11.10, or even manually changing opencl (and 2 other DLLs) like its explained on these forums, i am unable to get back the old performance

EDIT2:

After carefully reading your notes, i found out that the importat thing was to generate the (i guess kernel) binaries with the correct SDK. Since i had the ones from the correctly working SDK on CGMINER older versions folder, im fine now XD 2.2.0 is still slower than 2.1.1 tho.

No, I don't use remote desktop. ADL is working. Ckolivas has figured out the problem and made a temp fix. Read the thread a bit further.

[zefir]

Any system changes needed with Linux to move from 2.1.1 to 2.2.0?

I'm observing massive problems with the latest updates.

I kept the previous working binary as reference, but was not able to isolate the problem. First obvious thing is ADL fails to initialize:

Code:

As said, using the same APP and ADL version, same kernel. I also tried with deleting previous kernel binaries with the same result. I am using the current git HEAD for 2.2.0 (82af288e69).

Any ideas?

when using anything above intensity 9 on my 5970 w/ 11.12 drivers. The cpu usage is pegged... 9 and below cpu usage is 0%
Any reason why its higher on I 10+? thanks

You are only supposed to use 10+ with the new 79xx cards. I'm positive Con mentioned that somewhere around here.

just curious what mhash your getting with your 5970 using 11.12 ? I messed around with several different configurations over the last couple of days for mine and the best I came up with is 11.9 w/ cgminer 2.20 - I get a nice 820 mhash - woohoo!

btw: ckvolias do you know why Anubis web front end stopped working with the 2.2.0 upgrade?

thanks!

This is the infamous cpu bug.

[jake262144]

This is the infamous cpu bug.

No it's bloody damned not.
THE cpu bug would eat a whole core no matter what intensity/aggression you'd chosen.
It was caused by AMD's driver fuck-up and has since been fixed.
There have been some OS-specific CPU hogging issues, eg with Ubuntu.
Do the research first and don't post misleading and try not to post inaccurate information, k?

Tell me then why I don't have any cpu usage with even 12 intensity with 2.1, but have all up to 100% on one core (with 1 gpu miner) with all other sdk's (in case of Win7)? It's the same bug. It's a slight usage ~15-17% on one core, if I use buggy sdk and aggression 9, with 8 - zero usage. Higher intensity > higher cpu load with buggy sdk's, cept 8.

[-ck]

Calm down fellas. They're different CPU bugs. There are 3 in all. Either way intensity  above 9 is mostly harmful.

Changed API with the newer commands I would guess.

If you posted your driver version, OS and GPU config someone could try to unravel your issue but this is hardly the appropriate thread.
Proof by counter-example: a lot of miners moved to 11.11 or 11.12 driver and reported no CPU-hogging issues. Therefore, the major CPU-hogging flaw has been fixed.
Computers and operating systems are inherently very complex subjects and great many things can go wrong. Unexpected combinations of drivers, SDKs and system libraries can still peg the CPU but it's luckily relatively uncommon. Mixing x64 and x86 code can not only be a real pain but also result in undefined behavior.

EDIT:: Con, latest git works like a charm The GPU order has changed on my Debian machines, though.
EDIT:: Another donation is due as soon as my wallet recuperates.

I fixed it already, just said that he has the same bug. Sometimes it's a very minor cpu load with low intensity/aggression, but it's the same issue. Read this reply and 2 next ones.

The RPC API version is now 1.0
The README explains all the other changes to the API ...
Most notably, it mentions that the CPU|N command is no longer available on software not compiled with CPU support.
The README also says that you should check "cpucount" or "config" to determine if there is any CPU info available.
"config" also tells you if ADL is available and also if any GPU's use ADL - thus if the new ADL commands should succeed or fail.
