[Gate-users] Segmentation violation with GPU

[Jan-Nico Zaech]

Dear fellow GATE users,


I plan to use GATE for the simulation of CT imaging. Therefore I installed GATE8.0 on Ubuntu16.04 with GPU support, with the following software versions:


CUDA 8.0

Root 5.34/36 (built from source as GATE did not built otherwise)

GEANT4 10.3.3


The CT example from gpumacros in the GATE7.2 source does work on CPU, but the GPU-version crashes with the following message:


[Core-0] Initialization of geometry
[Core-0] Initialization of physics
### WARNING: G4EmProcessOptions class is obsolete and will be removed in the next public release
    Please, try to use G4EmParameters class and/or UI interface to EM parameters
[Core-0] Initialization of actors
[Core-0] "ResetData" = [ ResetData ]
[Core-0] "GateGPUIO_Input_delete" = [ GateGPUIO_Input_delete ]
[Core-0] "GateGPUIO_Input_new" = [ GateGPUIO_Input_new ]

 *** Break *** segmentation violation
