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

[Elmojo]

I see a bunch of stuff about SDKs flaoting around. Do I need to do anything with that or does that only apply to Linux/AMD/whatever?

I like using the AMD Catalyst 11.6 which includes the OpenCL SDK 2.4.  That seems to work pretty good for me.  But if you get one of the newer GPU's you may need to get a newer Catalyst version.  Post that question again when you get said GPU and someone will, I'm sure, have a more informed suggestion for you.

In the meantime, while I'm still on the GTX480, do I need to be concerned with anything SDK-related?

I don't know anything about Nvidia GPU or Cuda, so I couldn't say.

Hi Con,

in be8ad579 you fixed some missing includes in the modularized logging module. Was this required for Windows or OS/X builds?

I'm asking because I always perform full builds of all potential configuration combinations on my Linux system before I commit and never saw a problem with that missing include. Do you have some automated build scripts to check commits for regressions and QA? I'd like to ensure that my future modifications do not break anything before I issue a pull request.

Thanks,
Zefir

Windows. Manual build just before release usually

That applies to mining ...

Again, I have no idea about nVidia and CUDA but I even typed your google search for you and found this page:
http://developer.nvidia.com/cuda-downloads

No idea if you need something else to mine, but no doubt the fact that your NON-ATI miner doesn't work at all probably means you are missing something to make it work ... and at a wild guess it may be that? (I don't know)

Thanks for doing that search for me, I don't think I'd have ever thought to search for that particular string.
I'd downloading the GPU compuing SDK and the CUDA toolkit. They're massive downloads, about a gig between the 2.
It seems odd to me that we'd need development tools to run miners, but I guess I'll add that to the list of things I don't understand about mining! lol

It seems to me that if I were going to mine with an NVida card with the CUDA stuff already installed I would use a mining program that was built for that purpose, until I got a my AMD GPU that is.

Sam

I agree completely, is there one?
I have guiminer, but can't find a way to get it working with P2Pool, and I think that's the right pool for the future of BTC.
If you know of a more appropriate CUDA miner, I'd love to hear about it!

Ufasoft Miner 0.27 - Windows/Linux, x86/x64, SSE2/OpenCL/CUDA, Open Source.

Your making me look like I'm plugging someone else miner on the CGMiner list.  I'm really not trying to do that!!!!  I'm just trying to get you mining.  I don't know if it will work for you but it's worth a shot.

I read through the  the Ufssoft thread, but there doesn't seem to be any lilnks to the 0.27 version for windows, only 0.25.
I'll give it a shot.
Don't feel like you're directing me away from cgminer. I'll be back on it as soon as I get my AMD card!
I tried the CUDA SDK files, they made to difference. cgminer still crashes the GPU driver upon launch.

Always look in the mining software threads top post for the download links and latest version information.

Sam

Yeah, I did. There appears to be an error on the project page.
It shows info for version 0.25, but when you download and run it, it's actually 0.27.

Thanks to everyone for the tips and help.
I'm up and running on P2Pool with Ufaminer right now.
I'm hashing faster than ever (~150Mh/s) and no stales so far.
I'll be back to cgminer as soon as I get my grubby mitts on a decent AMD card.

If you know of a more appropriate CUDA miner, I'd love to hear about it!

rpcminer-cuda is the only CUDA miner, I think.
But rpcminer doesn't support longpolling or any other advanced features.
OpenCL miners are a little bit slower.

cgminer does it - but it seems no one who uses it knows what is required to install to get it working

[Endeavour79]

I have a question regarding the SDKs..

For HD5xxx users the SDK 2.1 is the fastest and I would like to use it.
Does it already contain all the functions we need for CGMINER, supporting GPUClock, Memory and Fan settings?
Is this related to SDK or driver version?

Driver has those functions. 11.6 or greater driver. SDK 2.1 should be fine.

Does it or Did it?  I see no references anymore to NVidia or CUDA on the top post.

cgminer mines fine on nvidia (if not the fastest)
python-pyopencl is the package you need on ubuntu

cgminer -n shows this:
[2012-02-14 13:27:59] CL Platform 0 vendor: NVIDIA Corporation
[2012-02-14 13:27:59] CL Platform 0 name: NVIDIA CUDA
[2012-02-14 13:27:59] CL Platform 0 version: OpenCL 1.1 CUDA 4.1.1

Presumably the most basic of cuda tools will work also on windows.

Just recently upgraded to cgminer 2.2.5 so maybe that has something to do with it

It might be the pool but I am only seeing it on the rig running 2.2.5 (11.2 driver, 2.5 SDK)

Normally have about 0.2% reject rate on this one rig I am hitting >5% and 98 or 99 are duplicate work errors.

Interesting. It is only recently that cgminer has been reporting the reject reason. This is the same GPU each time as well, which suggests more a bug in the (new) kernel code rather than from the pool. This may be related to vectors code. What kernel is in use on this and are vectors enabled? I'm guessing poclbm+2 vectors on the GPU in question.
