Hi Ding, I tested it myself, and I cannot reproduce it. The code runs well for me with CUDA13 (I am using 13.1 but most likely 13.0 is the same).
The "warning: xxxxxxx.h: [jitify] File not found" messages you saw are not errors. Those are warnings associated with perhaps some file structure changes on the CUDA side; I got them too (we may have to bear with them now), but the code runs fine afterwards. It's not clear to me why the ensuing memory error occurred (I didn't have them). It looks like a Windows dbghelp.dll problem in your case, rather than DEME's problem. You may be able to get more information regarding this error by running *compute-sanitizer --tool memcheck DEMdemo_BallDrop.exe* To see if it is indeed a host error. You may also want to check if your NVIDIA driver's version supports your current CUDA installation (by running *nvidia-smi*). In any case, the simplest solution may be using DEME in WSL2, rather than on plain Windows. It's more tested and you won't have dbghelp.dll problems there, that's for sure.
