Hi Anderson,
at the moment we don't do any GPU programming, but are actively looking
into it and may have something in the not-too-distant future, so I think
you are ok with no graphics card from our perspective. We do use some of
the computational routines in vtk though, so you'll need that even if you
aren't doing any rendering.
cheers,
Bruce

Dear all,
We are considering to buy a blade system, and FreeSurfer would be one of
the applications to run on it. We know that a 3D graphics card, with
support for OpenGL and built-in memory+GPU, is recommended. What we are
not sure is whether it is mandatory for all the FreeSurfer routines, of
if that is necessary only to render data in the screen, in particular,
with tksurfer.
If it is used only for display purposes, and not for real processing,
then we may consider having graphics card only in a few separate nodes,
that the users could access with an X-server (or maybe VNC with OpenGL
support).
Does it all makes sense, or do all and every computer must have their own
3D card for everything?
Thanks in advance!
Anderson
