LL with OpenCL

For example, when trying to compile 0.59, I was left wondering what openclsdkdefs.mk is supposed to be, and where I should find SDKApplication.hpp. I use Linux and I'm not exactly a beginner with these things, but for some reason I feel completely lost here, as if I was missing some essential package (besides AMD APP SDK and clAmdFft, of course).

One reason why I mention this now is that I recently released an automatic work assignment/submission tool for mfakto, and I'd like to extend it for LL testing. Of course, I would try CudaLucas if I had any Nvidia hardware.

This may help.
Also, openclsdkdefs.mk and SDKApplication.hpp is located in the AMD APP SDK. Although, you may want to wait till the switch to clLucas/clFFT is done. Assuming that you have installed AMD APP SDK in the default location on linux, it should be at /opt/AMDAPP/samples/opencl/SDKUtil/include

A few notes.
Does -aggressive work? it seems turning that on uses a lot of cpu.
Also, might want to consider switching from clamdfft to clfft, (clfft.h)

Please check large exponent,like 36666666.
clfft.h is right.My mistake.

Ok, so if anyone has a 58xx+,68xx+,77xx+ and want to test out a few things, PM me. (Windows x64, 32 bit if needed)

Thanks! It seems my APP SDK 2.5 is too old; Gentoo doesn't have packages for the newest versions, and I have some software where 2.5 is recommended - I guess I'll have to install by hand.

Kracker,
What are the driver and SDK requirements for the test you send?
Catalyst 13.4 gives me a missing libgcc_s_seh-1.dll error, so I'm downloading Catalyst 13.6Beta2 and APP SDK v2.8.1.0 now and will try again :).

:facepalm: Sorry, forgot to link it statically! you don't need the appsdk and catalyst, I'll give you the dll's...

[kracker]

Here they are. also to @LaurV. Sorry again.

Thanks, now it's working!
Windows 7 x64
Catalyst 13.4
AMD HD7950 @800MHz (downclocked it to reference clocks)

Nice GPU load on 36,666,666!
See attached screenshot

And also the test on the much smaller expo (lower GPU load).
