[Gate-users] Segmentation violation with GPU

[David Boersma]

Hi Jan-Nico,

(1) For reproducing your crash it might be of interest what kind of 
graphics card you have.
(2) Sadly, the GPU support will be discontinued in future releases of 
GATE. You may want to take a look at GGEMS: http://www.ggems.fr/

HTH,
David Boersma
