1) Message boards : Number crunching : All my GPU WU finishes "computation error" after a few seconds !!! (Message 8031)

Hello,
This seems to be related to https://moowrap.net/forum_thread.php?id=510&postid=7846
I have a very similar problem : with Dnetc 1.04 and AMD application, it is impossible to compute on AMD GPU. The application is rather using the integrated GPU (Intel HD Graphics 4600 on a Core i7 4790K). I have tested separately with two GPU : a HD 7970 and a R9 Fury.

I am currently testing with a Nvidia GPU, and results are similar: only the Intel GPU is computing. In fact, when we start the client in command line, we obtain no presence about the nvidia gpu, at least in OpenCL mode. However, it is correctly detected in boinc, both as Cuda and Opencl device.
dnetc520-win32-x86-opencl.exe -cpuinfo --> Intel GPU only
dnetc520-win64-amd64.exe -cpuinfo --> Intel GPU only
dnetc518-win32-x86-cuda31.exe -cpuinfo --> Nvidia GPU only

The problem is the used distributed.net client itself that seems to be from 2012 and not even know the -gpuinfo option. Thus, it is detecting the first opencl platform (intel) and not the following ones (nvidia or amd). The afore mentioned solution is not suitable as it will perturb opencl detection on other projects. The best solution would be to update and recompile the dnetc clients. In the mean time, on Nvidia one can use an app_info.xml file forcing the use of the cuda client. On AMD, one need to remove intel opencl drivers, as proposed above.
For my 1050 TI, the solution looked like this:
- if present, the Intel video card driver must be uninstalled
- under
HKLM\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors
you have to delete all entries except the one from the manufacturer of your videocard
I hope i this will help you.
2) Message boards : Number crunching : Legacy Dual GPUs, BOINC assigned work to both but only one with load (Message 7846)

I have 2 legacy ATI Radeon HD 3870 cards. When using Moo wrapper, BOINC assigns 2 tasks, 1 for each GPU. I used GPU-Z to investigate the GPUs when i noticed the one was running very hot compared to the other and that is when I discovered that only of the cards had any load. The one card runs 100% load while the other does nothing.


Hello,

It is the same that was suggested there: https://moowrap.net/forum_thread.php?id=484&postid=7674#7674

I have tried to update the amd driver, and to blacklist the gpu, without success. Could it be a command line switch to add in an app_config.xml file, to select the correct gpu ?

Thanks
