All OpenGL code uses the GPU (Graphics Processing Unit) just like all
Cinelerra code use the CPU (Central Processing Unit). So if you have
Settings->Preferences->Playback A/B, Video Driver set to X11-OpenGL you are
using the GPU for:
- line drawings
- all GL primitive operations
If you are specifically inquiring about use of CUDA software with the
meaning as follows:
"CUDA is an API model which allows software developers to use a
CUDA-enabled Graphics Processing Unit for general purpose processing, aka
GPGPU (General-Purpose computing on Graphics Processing Units). The CUDA
platform is a software layer that gives direct access to the GPU's virtual
instruction set and parallel computational elements." (paraphrased from
...then the answer is "no". Probably about a year or 2 ago, GG tested Cuda
code with Cinelerra-GG. It did not perform well. Some operations
performed better but, sadly, most of what Cin does, it did not do well.
Cuda is mostly a "block oriented algorithm" which works well for such
things as "a flock of birds all flying next to each other".
After hearing this from GG, I do not think it would be appropriate to
include this in the manual, although I am always looking for more to add.
