CGMiner 2.1.1 binary + Ubuntu 11.10 64 bits + Catalyst ?

[ThiagoCMC]

Guys,

 What version of Catalyst should I use with Ubuntu 11.10 and CGMiner-2.1.1 binary?

 I already tried a lots of combinations, none works. In all combinations I've tried, my CGMiner consumes 100% of my CPU for nothing.

 I see that with new version, the SDK is not necessary, confirm?!

Best!
Thiago

I'm currently using 11.6 with APP SDK 2.4 on Ubuntu 11.10 32 bit with no issues.

AMD made it sound like they fixed the issue in 11.12 though (I know it fixed the CPU bug on my 2 Windows boxes anyways):

Also, if none of this works, try using "export GPU_USE_SYNC_OBJECTS=1".

GPU_USE_SYNC_OBJECTS=1 worked for me! Cheers!

It is impossible to compile fglx kernel module from Catalyst 11.6 on top of Linux 3.0 that come with Ubuntu 11.10. At least at the 64 bits version. The kernel module does not compile.

I do not have any 32 bits systems...

I just installed Ubuntu 11.10 again, at my mining rig with 2x5870, with Catalyst 11.9 and sdk v2.4... CGMiner consumes 100% of CPU, but the mining is running at my GPU, of course...

I would LOVE to know what combo ckolivas is using at his mining rig. He tells only that the cgminer binary is for Ubuntu 11.10 but, he does not tell us what Catalyst / SDK to use.   

My stable combo is Ubuntu 11.04 / Catalyst 11.6 / SDK v2.4 / CGMiner 2.1.2 binary dist with some workarounds.

I'm desperate to upgrade to Ubuntu 11.10.

I'll try next time with Catalyst 11.12 and SDK v2.6... Anyone already tried this combo?!

Thanks!

Not for me...

Ubuntu 11.10 64 bits + Catalyst 11.12 + CGMiner 2.1.2 = crap... 100% usage...

I noted that with Catalyst 11.12 it is not necessary to install SDK. Right?!

FINALYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY!!!

The option "GPU_USE_SYNC_OBJECTS=1" drops the CPU consumption of CGminer from +100% to 3~5%!!!

AWESOME!!!

Time to upgrade all my mining rigs!! 

There is no need for SDK with Catalyst 11.12 and CGMiner 2.1.2 binary!!  ^_^

Well there is but AMD started including the SDK in the driver.  They have been doing this on windows for sometime now (11.6?).

Ohh CRAP!!

Catalyst 11.12 solves the 100% CPU BUG for my mining rig with 2 5870...

Now, I do the SAME thing at my 2 5970 box and... Huge shit...

CGMiner says:

"ADL found more devices than opencl"

Only one GPU core of four works... Slooow... Sometimes, the machine just halt immediately...

"Catalyst 11.6 + sdk v2.4 + cgminer 2.1.2" rules, there is no better combo available for mining.

I would love to see what Catalyst version ckolivas is using at his rigs powered by Ubuntu 11.10.

"ADL found more devices than opencl"

I have this same error and have no idea how to correct this. Running a windows box.

Tried 11.6, 11.10, 11.11, 11.12
No love, same problem.
