[QUOTE=preda;492577]On Ubuntu 18.04 (kernel 4.15), I finally managed to install ROCm 1.8.2; (previously I was using amdgpu-pro 18.20). The performance for "100M digits" improved from 9.17ms/it to 8.36ms/it (on otherwise same setup).

Warning for others trying ROCm 1.8.2, there may be new errors when running on wavefront exponents (80M). (if there are, they are detected correctly, the result is still reliable). I need to keep an eye on these, I'm not sure yet who's to blame (me or ROCm).[/QUOTE]

I hear newer kernels offer even better performance and more stability for gaming. Have you tried updating the kernel to see if that also makes a difference?

[QUOTE=Mark Rose;492584]I hear newer kernels offer even better performance and more stability for gaming. Have you tried updating the kernel to see if that also makes a difference?[/QUOTE]

I was using kernel 4.17 before (with amdgpu-pro), but ROCm 1.8.2 only installs on 4.15, thus I needed to dial back the kernel for ROCm's sake.

[QUOTE=preda;491979]Yes, but you're in the danger zone at that bits-per-word level. You're likely to encounter numerical errors, that will trigger retries. That works fine, only that it costs some time. In such a situation it may be worth starting the exponent with a lower "block size" than the default of 400, with "-block 100" or "-block 200".[/QUOTE]


Programmer advice is often wise: at approximately 8% it gave the first error, so I am back to FFT 18M for this exponent.

I'm surprised 4.15 works now, not long ago I had to use 4.13. That gives me hope that support for 4.17 is not far off, it'd be nice to be able to use the latest kernel and ROCm and that's it.

I started with kernel 4.15 and am now using an interim version 4.17-trunk which works well with amdgpu-pro.

Any luck with this? I have no idea what I'm doing, I just want to run a more updated version than 1.9.

[QUOTE=kriesel;491799]That worked great for v2.0. Thanks again for that. I tried again recently with V3.3 (starting from step 5) and ran into errors.
So, updated the msys64 installation with pacman -Syu until all was up to date. Tried again. Looked at the gpuowl makefile and extrapolated from it (for openOwL)
[CODE]g++ -O2 -DREV=\"bc4a29f\" -Wall -Werror -std=c++14 OpenGpu.cpp Gpu.cpp common.cpp gpuowl.cpp -o openowl -lOpenCL -L/c/Windows/System32[/CODE]Still errors. Could you update 7) for V3.3 please?

Haven't tried it yet, but I extrapolate for cudaowl to: [CODE]nvcc -O2 -DREV=\"bc4a29f\" -o cudaowl CudaGpu.cu Gpu.cpp common.cpp gpuowl.cpp -lcufft[/CODE] (Don't have nvcc installed on a system with msys2 yet.)
And lastly, fftbench: [CODE]nvcc -O2 -o fftbench fftbench.cu -lcufft[/CODE][/QUOTE]

[QUOTE=endless mike;493050]Any luck with this? I have no idea what I'm doing, I just want to run a more updated version than 1.9.[/QUOTE]
Not here. Complete uninstall and reinstall of the msys2 environment is still on the to-do list.
Maybe kracker has had better luck?

Does anyone know what happened to the AMD APP SDK?
Formerly available at [URL]https://developer.amd.com/amd-accelerated-parallel-processing-app-sdk/[/URL] it now produces a 404 error. Their site map does not show it. Search for "app sdk" yields a license page hit that fails to open properly. Is it gone, or just renamed?
The "tools and SDKs" page yields nothing equivalent.

See step 2 of [URL]http://www.mersenneforum.org/showpost.php?p=483209&postcount=356[/URL] for building gpuowl

Last time I tried this, on my sole amd gpu system, an installer program v1.4.87-1 of a few MB put 150MB on the system disk, 5 directories deep. My notes from March say, shut down apps first; this does an unannounced system shutdown!
