I don't found anything about this phrase in the log:

can't fetch AMD/ATI GPU: project is backed off

[work_fetch] share 0.000 project is backed off  (resource backoff: 17742.15, inc 19200.00)



What is its meaning?

Hello,

Thank you for you time

libaticalrt.so
is the old ATI driver before OpenCL support.
From this forum:


BOINC does GPU detection by trying to load various libraries and seeing what they report. libaticalrt.so is the library needed for CAL / Brook+ GPU applications.
CAL is what ATI (and later AMD) offered for GPGPU applications before they switched to OpenCL. CAL has been available only on ATI GPUs. And since some time ago AMD dropped support for CAL in hardware and drivers.

I have enabled these check box:



Now i see in the Event Log these messages:

Post:
Is there a minimum requirement list that the GPU must respect to have a wortk unit?

For example:

    1 GiB RAM


    double precision support

Hello,

Thank you for your answers

I have activated all computing flags here in the project: CPU, ATI GPU and NVIDIA GPU



The driver is Gallium 3D Clover Mesa driver, latests version: 22.0.1

I did:

gpasswd -a boinc video


so boinc can see the GPU

In the Event Log, at the beginning i have:

But i don't receive any GPU tasks

Can I activate a debug log for the Milkyway@Home client?

So, only these GPU are compatible:


    (1.000) AMD Radeon FirePro W8100
    (0.852) Radeon RX 580 Series
    (0.770) Radeon RX 570 Series
    (0.549) AMD Radeon FirePro W9100
    (0.405) AMD Radeon R9 200 Series 


Go to computing drop down there is a huge list of GPU’s there.
Thank you

7) Questions and Answers : Unix/Linux : GPU compatibility (Message 72745)
Posted 13 Apr 2022 by Verona Group [VENETO]
Post:
Hello,

I have a very old GPU in a Linux System:

OpenCL: AMD/ATI GPU 0: AMD CAICOS (DRM 2.50.0 / 5.17.1-arch1-1, LLVM 13.0.1) (driver version 22.0.1, device version OpenCL 1.2 Mesa 22.0.1, 1024MB, 1024MB available, 100 GFLOPS peak)


I would like to know if this GPU is compatible with Milkyway@home
The Linux system is:

$ uname -a
Linux boinc 5.17.1-arch1-1 #1 SMP PREEMPT Mon, 28 Mar 2022 20:55:33 +0000 x86_64 GNU/Linux


Thank you
