Hi,
I think it's a user's question, but quite technical and with the dev
version, so I'm posting it here.
I've been using darktable since the 1.x days, maybe longer. I have an
ancient Core2 Duo machine with just 4 GB of RAM and an NVidia GTX 650
with 2 GB onboard.
For that reason, I have used the instructions for 32-bit systems, even
though I run 64-bit Linux
(https://darktable.gitlab.io/doc/en/special_topics_chapter.html#darktable_and_memory_32bit).
Namely:
worker_threads=1
cache_memory=268435456
host_memory_limit=500
opencl_memory_headroom=600
opencl_memory_requirement=600
singlebuffer_limit=8
However, no matter what I do (e.g. increasing/decreasing opencl memory
headroom and requirement), I keep getting '[opencl_atrous] couldn't
enqueue kernel! -4' with the version compiled from master. On the UI,
I get: "tiling failed for module 'atrous'. output may be garbled". At
the console:
