GPU driver crashes after becoming unresponsive (Windows)Last update: A. Peternier, 16/11/2016
1. GPU used both for graphics and computeIn most cases, computers have one single GPU that is connected to a display and used for graphics rendering by the operating system. When such GPUs are OpenCL-enabled and meet SARscape's minimum requirements, they can be used also to speedup the processing.
2. Timeout Detection and Recovery (TDR) problemWhen one same GPU is connected to a display and, at the same time, is it used as OpenCL device for intensive SARscape processing, the GPU might become so heavily loaded that graphical operations stutter or freeze. After a specific threshold (which is of 2 seconds, by default) the operating system resets the GPU driver with an error (e.g., "Display driver stopped responsing and has recovered").
This problem happens under Windows when a GPU is set to use the Windows Display Driver Model (WDDM) mode. With the more recent versions of Windows, this same problem is present even on GPUs in WDDM mode although not connected to any display.
