I hope all is well Reb!

I am almost out of CPU workunits as well.

There is still running a new base and have a memory leak, been carefully at the moment, also have read some issues with older bases and want to try to double check them. I will add some more work soon.

These are the relevant lines from the BOINC event log. I think you're right, you've "upgraded" the SRBASE software past the capabilities of my video card.

Its a Kepler card with cc3.0, I have changed to cc3.0 in plan_class for cuda10. If its not working for some cards I will change it back.

We have run out of CPU tasks.

Some new work is prepared...

... looks like your card is too old.

What is "too old", what GPUs are supported?

I have found some specs by google with cc5 if this is right.

I am no longer receiving any GPU tasks for SRBase. I am getting a message in the debug log

2024-03-28 11:54:39 | SRBase | Message from server: NVIDIA GPU: Upgrade to the latest driver to process tasks using your computer's GPU

I have the latest drivers from the NVIDIA web site. What exactly are you looking for?

Windows 10
Quadro K2000
Driver 30.0.14.7482

Thanks

What cuda version do you have installed? cc6.0+ is supported, looks like your card is too old. I see you have some badges. When did you get the last WUs?

1st one completed and returned from RX6800.

https://srbase.my-firewall.org/sr5/result.php?resultid=147398812

Another is running on the RX6800XT now.

So was it a null assigned to $GPU_DEVICE_NUM in job_TF_l64m1_00039.xml?

2 done and reported from RX6800XT. They are sub 4 minutes clock time on this card.

https://srbase.my-firewall.org/sr5/result.php?resultid=147174011

Thank you so much for walking thru the testing with us.

tschuess, Skip

Its fine to see if its running :)

nope, the app itself needed a new libfile from the new rocm driver and some other changes. The console was everytime successfully to run but different from running in boinc, was very frustrating. Now on the 6400 it was fine.
