[Gate-users] GPU buffer size

[David Boersma]

Dear Ji Hye Han,

I wish I could help you, because GPU computing is cool, but unfortunately the GPU code in Gate has not been maintained since a couple of years now and we intend to drop it completely from future releases. The original developers have started a standalone Geant4/GPU-based simulation app called GGEMS, maybe that is a more fruitful option for you. However, it's unclear to me whether it's actually released or not.

Betreff: [Gate-users] GPU buffer size

Dear Gate-developers,

I used the following code to simulate on a GPU.
examples -> gpumacros -> ct -> main-gpu.cpp

 # GPU Tracking
/gate/actor/addActor                  GPUTransTomoActor gpuactor
/gate/actor/gpuactor/attachTo         patient
/gate/actor/gpuactor/setGPUDeviceID   1
/gate/actor/gpuactor/setGPUBufferSize 10000000

Increasing setGPUBufferSize makes the data empty.
Is 10^7 the maximum buffer size?
