I did not find anything in the descriptions of the program about using
the GPU. Is there such a possibility? Where can I read about it?
If we understand what you are asking correctly, here is what gg had to say:
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
- fill
- 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 Wikipedia).
...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. GG/phyllis
