I’ve never had it before, either, and I’ve been using OpenCL on this same laptop / OS since I got it last January. But it’s OpenCL related – When disabled, the issue vanishes; enable OpenCL and it’s back.
Further Windows details, if relevant:
- Version 21H2
- Build 22000.613
I get no output at all from darktable.exe -d opencl -d (running 3.9.0+1370~g95646f9f3 downloaded from the link in the May 1 “Windows insider” post). Here are my darktablerc OpenCL settings (based in part on watching Aurelien’s video on OpenCL tuning):
opencl_async_pixelpipe=false
opencl_avoid_atomics=false
opencl_checksum=1633631460
opencl_device_priority=*/!0,*/*/*
opencl_disable_drivers_blacklist=false
opencl_library=
opencl_mandatory_timeout=2000
opencl_memory_headroom=300
opencl_memory_requirement=768
opencl_micro_nap=100
opencl_number_event_handles=25
opencl_scheduling_profile=default
opencl_size_roundup=16
opencl_synch_cache=false
opencl_tuning_mode=nothing
opencl_use_cpu_devices=false
opencl_use_pinned_memory=false
Once again, these have worked in the past. After recent updates, I believe some of the GUI OpenCL options have changed slightly, but I’ve not modified anything.
How do I go about troubleshooting this? I’m not OpenCL guru, to say the least. My laptop isn’t a fire-breather by any means but it’s not ancient. Still, I’d like any performance wins OpenCL can offer.
Thanks.
