[Gate-users] Running GATE on GPU

[David Sarrut]

Hello Zhengzhi,

yes sorry, GPU part is no more maintained. It still is viewable in the
history of git to keep the memory, but probably difficult to make it work.

The current best way to speed up simulation is
1) to optimize your physics (cut), geometry (less voxels), etc
2) to run several Gate in parallel, via several jobs (with 56 cores, this
is nice!), providing that you use 'auto' as the random seed to avoid
reproducing the exact same simulation. You will have to merge results at
the end.

Sincerely,
David
