Jeremy,
1) I believe that X11.app is virtualized on a single GPU, even if
windows are scattered on multiple monitor attached to multiple
GPUs. Am I right?
X11.app is not virtualized in any way. It's a completely native
application.
I think you're getting confused by the X11 architectural model.
I did not express myself properly, sorry. Virtualization is not the
suitable word. And I'm familiar with the X11 model, though not with
the details of it's interaction with OGL :)
The GLX calls are dispatched to OpenGL.framework. I do not honestly
know how all the internals of OpenGL.framework behave, but it should
render on the GPU associated with the monitor on which your window
lies.
According to this, if both simulations are displayed each on a
separate screen, attached to a separate GPU, I would achieve what I'm
looking for. I'll test that ASAP.
Thanks for the help,
Antoine
