William, You got the architecture right. The point is not having to render images and treat UI events, thus having all processing power for mathematical computation. X Windows System and Wayland are memory and CPU hogs and in some cases those resources are at a premium...
As I read the code, trying to figure out how WSTJ-X works, I notice how tightly coupled UI and data processing are. I understand it can be easier to show things on the GUI, but decoupling those could allow for some different UX (text-only, for example) or, as I suggested, some "smart" remoting. To be 100% honest, the distributed processing approach I proposed is just a thought experiment on how to decouple the many modules. Having each "module" on a different machine is usually how I think when I try to decouple complex stuff. I'll keep studying the code to try and figure out how it would be possible... 73 Rafael On Wed, Feb 28, 2024 at 1:01 PM William Smith via wsjt-devel < wsjt-devel@lists.sourceforge.net> wrote: > I get what you were trying to do, and it is not a perfect solution, but > many people use VNC or some other kind of remote desktop protocol to > remotely control the computer that is running WSJT. > > Yes, it would be much better to unload the GUI and the output video > requirements from the poor Raspberry Pi and let that run on some machine > that has a lot more available horsepower.
