A new batch of 50k tests is uploading.

The runtime is ~4h40min on a RX5500 XT and decreasing on higher ranges.

The batch name has TF_76-77_ ...

After all 75-76 WUs + resends are done you will see an increase in runtime. GPU in progress will be changed after the challenge.

Let's see how long this takes on my 4090 in the 50% TBP sweetspot :)

Yea, but I guess this was not limited to 50% TBP.
With 50% TBP mine now needed around 15-16 Minutes.

What card do you have? iGPU is not supported.

Do you have enabled AMD in your account prefs?

Your host has no GPU listed. Check your driver and boinc event log.

I run multiple GPU (a 1060 and a 960). I have to tell BOINC to run both cards, and manage what projects use what, since they are older cards and certain projects don't run well on certain cards. I don't know if this would help you, but I have to put this in my cc_config.xml located in /boinc-client/ directory:

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>

<exclude_gpu>
<url>https://einstein.phys.uwm.edu/</url>
<device_num>1</device_num>
<type>NVIDIA</type>
</exclude_gpu>

<exclude_gpu>
<url>http://www.primegrid.com/</url>
<device_num>1</device_num>
<type>NVIDIA</type>
</exclude_gpu>

<exclude_gpu>
<url>https://srbase.my-firewall.org/sr5/</url>
<device_num>0</device_num>
<type>NVIDIA</type>
</exclude_gpu>

<exclude_gpu>
<url>https://gpugrid.net/gpugrid/</url>
<device_num>0</device_num>
<type>NVIDIA</type>
</exclude_gpu>
</options>
</cc_config>

You might try that. You don't need any of the exclude rules unless you want to try air traffic controlling. Really the only part that might help is the <use_all_gpus>1</use_all_gpus>

If you're on Windows be sure to restart after making the changes to reload the cc_config.xml, or if you're on Linux from the terminal sudo systemctl restart boinc-client.

Thanks. My value was zero. Will update and report back after a restart.

Nothing helped. I made a bug report in the BOINC repo.

So BOINC was installed as a service which blocked gpu tasks. After reinstalling the manager, gpu tasks populated but they all suffered computational errors immediately.

From the event log: Starting task X > (4sec later) Computation for task X finished > Output file Y for task X absent > repeat with next task.

Disable your iGPU in cc_config, should be device 0

I disabled it in BIOS before heading to work and "iGPU" isn't present in my cc_config file. It looks like everything is sorted out; 12 TF_76-77* tasks were completed while awhile. Thank you for the assistance!
