Hi,
Hi.
Here is a GPU issue related to chimerax and coot (0.9.8) on the Linux system.
OK...
To be able to call GPU in chimerax, I put the nvidia invoke in .bashrc file.
I don't know what it means to call the GPU in ChimeraX. I don't know
what the nvidia invoke is.
Perhaps you are refering to an environment variable?
Chimerax works,
In what way? What changes?
however, this will stop the working for coot to display structure at the
following view modes: `mono`, `side by side stereo`, and `side by side (wall
eyed)`.
What do you mean by "stop the working"? That Coot doesn't start up? Or
freezes?
It
It? meaning Coot or the graphics card?
still works if I click 'hardware stereo' or 'Zalman Stereo' and I can see it
in `nvidia-smi`.
"see it"? The graphics card?
Without GPU, each mode works fine.
Without the graphics card, Coot will fall back to software rendering on
the backend. Not many people these days think that that is "fine."
I wonder if we shouldn't run coot with GPU or if there are some potential
issues.
Does anyone have any idea about this? Thanks!
For most people, Coot uses the GPU whether they like it or not.
The advice I can give you is trite: use whatever gives you the best FPS.
I'm not sure that I've been of much help.
