A lot of the newer Nvidia graphics cards have a compute capability of 5.2 which isn’t listed in that file by default (in that case you would replace XX with 52). <o:p></o:p> <o:p> </o:p> Also I have found that when configuring the installation using CMake, the option “CUDA_SDK_ROOT_DIR” is left blank by default. Make sure it is linked to your CUDA install. The path should match the option for “CUDA_TOOLKIT_ROOT_DIR”.<o:p></o:p> <o:p> </o:p> After making the above changes, recompile Gate and try your simulation again.<o:p></o:p> <o:p> </o:p> I hope this helps you fix your problem,<o:p></o:p> <o:p> </o:p> Nathan Lo<o:p></o:p> <o:p> </o:p> <o:p> </o:p> <div> <div style="border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in"> From: gate-users-bounces@lists.opengatecollaboration.org [mailto:gate-users-bounces@lists.opengatecollaboration.org] On Behalf Of Zakarumit.Z@seznam.cz Sent: Wednesday, June 22, 2016 3:08 AM To: gate-users@lists.opengatecollaboration.org Subject: [Gate-users] GPU simulation exception<o:p></o:p> </div> </div> <o:p> </o:p> <div> Hello,<o:p></o:p> I have created a simple PET geometry with voxel phantom that already works when run on CPU. Hovewer, I would like to try GPU acceleration as well, but when I modify the code and run it, I receive following error:<o:p></o:p> <o:p> </o:p> :: Stacks init :: Materials init :: Phantom init :: Activities init :: Start GPU :: Rnd ok :: Generation ok WARNING - GPU reachs max step :: Tracking ok :: Stop GPU (time 1.734591e-01 s) -------- EEEE ------- G4Exception-START -------- EEEE ------- *** G4Exception : GeomNav0003 issued by : G4PhantomParameterisation::GetReplicaNo() Point outside voxels! localPoint - (-nan,-nan,-nan) - is outside container solid: pacient_solid *** Fatal Error In Argument *** core dump *** -------- EEEE -------- G4Exception-END --------- EEEE ------- *** G4Exception: Aborting execution ***<o:p></o:p> <o:p> </o:p> I thought it might be just me making a mistake somewhere but I receive exactly the same error when launching GPU PET macro from the example folder. I am grateful for any advice regarding the matter and what might be causing it.
