What is the status of GPU support and multiprocessing in hugin and
enblend?
I've read a lot of stuff on the subject but I can't tell what is
current or out of date. The hugin version from the ubuntu repo seems
very slow and does not appear to be using the gpu or
multirprocessing. So, I want to build hugin and enblend, and enable
those options, if possible.
Cheers.
Hmm. Running Debian 11 here, I have enblend 4.2, and it uses every
core on my i9 CPU. Under Preferences > Stitching (2), Hugin has Number
of threads set to 0, for automatic detection.
Using Hugin Version: Pre-Release 2021.1.0.33b93e37f209.
The only point where Hugin uses a GPU is when remapping images. That's
controlled under Preferences > Programs > Nona, Use GPU for remapping.
My laptop has both Intel Intel and Nvidia graphics. Apparently that's
controlled through the update-glx setting, but I haven't tried
switching to the Nvidia to see if it's any faster.
Well, I did some testing, and it looks like no matter what I set the GLX
provider for, Hugin still uses only the UHD630. Oh, well!
