Hello All,

I have an AMD Radeon HD 6670 card that I am attempting to use on MW, but I can't seem to get any work units.
Is anyone else having luck using this old card?
Thanks,
Allen

The HD 6670 does not have double precision required by MW.

Milkyway@Home: Notice from server
ATI GPU R600 (R38xx) does not support OpenCL

I'm quite certain that it does though. Any idea what's going on?


Usually it means the OpenCL driver isn't loaded but in your case it is, at least it is on the Darwin based pc, the Windows based pc has no drivers loaded for the gpu at all.

Try running the TF tasks at the project SRBase and see if it works there, they don't require OpenCL but do require drivers so if you are trying to use the Windows pc you will need to loads drivers for that pc. I don't think MilkyWay upped the minimum requirement for the version of OpenCL here to 1.2 but if so that could be your problem too, I just checked my pc's and all mine are running version 1.2 or better.

Message 70434 - Posted: 25 Jan 2021, 3:20:23 UTC

Have been running MW on an Asus mobo, Intel Core i7-3930K Hexa-Core CPU, Windows 10 Enterprise x64, NVIDIA GTX 1070 Ti, and its Cuda cores were crunching numbers very well. Last week I built a new system especially for targeting this kind of task and others like it. Moved my NVIDIA GPU to the new system, installed MW but now, no Cuda number crunching. Here are the differences between the two configurations.

The new system is ASRock 570 Creator mobo, AMD Ryzen 9 3900xt CPU, Windows 10 Enterprise x64, NVIDIA GTX 1070 Ti, and this time when I installed BOINC I did so without installing the Oracle VM bundle.

Is leaving the Oracle VM out, the cause for no Cuda processing? Or could there be another reason?
Any guidance would be helpful from someone who's seen this kind of issue before.

In case the question is asked, yes, the OpenCL drivers are installed.

I've solved my problem but not sure why it works this way, maybe someone with greater insight can enlighten me. On the last installation of BONIC, I installed it as a service in addition to installing it without Oracle Virtual Box. After reinstalling as a desktop app, not a service, the GPU Cuda cores are now crunching numbers again. I've done some queries on this site in an effort to find something that explains this but found nothing that speaks to this directly.

Long time since I ran BOINC on Windows, but I seem to recall that if you run it as a service it can't see the GPU(s). Indeed, that's confirmed at https://boinc.berkeley.edu/wiki/GPU_computing where it says
Warning: On Windows do not install BOINC in Protected Access Execution (PAE) mode aka service mode (6.4.5 - 7.0.28) or Service Install mode (7.0.64 and above). If you do, BOINC will not be able to detect or use your GPU.
(working on the assumption that that is still correct...)

Hope that helps - Al.

You beat me to it, YES that's true AND it's also true that if you use multiple log ins for your pc the gpu will stop working as soon as the first person is not the person running the desktop. For example a lab where multiple people use the same pc...the gpu will run for the original person each day but as soon as some one else logs in the gpu stops and won't run again until the original person logs back in again.

Thanks for the info. I finally realized I missed the clear and direct answer to this question when installing the app. The Advanced dialog clearly states that GPU crunching won't work if the app is installed as a service. My bad! Just goes to show how getting in a hurry, ends up wasting more time than reading the directions beforehand.
