I'm running a matlab simulation code using an iterative matrix equation solver. This solver is called on the GPU every few time steps in a time stepping loop. This goes well for some dozens of time steps (although the computations gradually slow down...) until the screen goes black for a short instant of time and the simulation crashes with the following error message:
Error using gpuArray/subsasgn
An unexpected error occurred during CUDA execution. The CUDA error was:
After this, Matlab does not recognize the GPU device anymore: the command
Error using gpuDevice (line 26)
An unexpected error occurred trying to retrieve CUDA device properties. The CUDA error was:
Restarting matlab is not sufficient to restore the GPU. Restarting the PC is.
I'm running matlab 2016b on windows 10, using an Nvidia TITAN X (Pascal) GPU with the newest driver installed.
Do the above symptoms inspire anyone for a diagnosis of this problem?
