[Gate-users] Running GATE on GPU

[Albert Grace Lieu]

Dear Gate users,

First thing first, can we still possibly use the GATE GPU version? I am
trying to run a GATE simulation on GPU (GATE V8.2, CUDA-10.1), but end up
with a similar problem reported [1]
<https://github.com/OpenGATE/Gate/issues/188> by Thomas Funck. In the
post, David Sarrut said "Hello, sorry the GPU part is no more maintained
...". Although it might not be maintained anymore (which is really
unfortunate), can one still use, say with the old GATE version? Without
CUDA acceleration, GATE running with 56 cores is still painfully slow.
Please give me any help.

Thanks a lot,
Sincerely

Zhengzhi
