Hello all,

Am I the only one with GPU tasks getting stuck at 0.01% on 7900 XTX ?

See here for details: https://asteroidsathome.net/boinc/forum_thread.php?id=973&postid=8103

Best regards, Samuel

Judging by https://asteroidsathome.net/boinc/gpu_list.php your card isn't mentioned. So either not many people are using one here, or nobody with one has managed to complete a task. I'm not sure if that lists every card used or only the popular ones.
I see yours last worked on 30 Sept. Not sure if the list I linked to above shows back that far.

As of friday october 13th, i have A@H work units on my Amd radeon rx vega 11 (gpu) again.

I'm having a bit of trouble with Fedora 40 on a Ryzen 7 4700U APU. It will happily request GPU tasks, but they immediately error out on starting:

Could this be some sort of permission issue?

Could be a permission issue. I don't know anything about AMD gpu drivers but it looks like access to or missing whatever is the AMD equivalent of a compiler like what nvcc does for Nvidia cards.

1/ HSA_STATUS_ERROR_OUT_OF_RESOURCES is likely due to outdated drivers https://askubuntu.com/questions/1435708/hsa-status-error-out-of-resources-rocm5-1-1-ubuntu-22-04
could you try more recent drivers if there are any for Vegas?

2/ "out of host memory" means the selected intensity is too high
your driver reports CL_DEVICE_MAX_SAMPLERS = 5686, but we expect 16, 32 etc.
Grid dim: 79604 = 2 * 7 * 5686
in comparison with 7900 xtx
Grid dim: 1536 = 2 * 48 * 16

The driver refuses to compile the application since the required intensity is insanely high.

This issue can be resolved in the app by modifying how we calculate the optimal intensity for the target GPU. We should likely avoid using CL_DEVICE_MAX_SAMPLERS in the formula.
