By default, Windows constantly monitors the GPU and driver to make sure it is responding as expected (called Timeout Detection and Recovery, or TDR). If it does not respond after 2 seconds, it will reset the driver. This is problematic for general purpose GPU computing because intensive calculations may take longer than 2 seconds.

You can and should edit the registry to increase the timeout delay. The steps are detailed below:

1. Open the Windows Registry Editor. This can be accomplished by a) search for 'Registry Editor' in the Windows search bar, b) Right-click the Windows start icon, select "Run" and type in "regedit".
2. Navigate to: Computer\HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers in the left browser pane or address bar.

3. If the "TdrDelay" key does not exist, add it by performing the following:

   a. Edit > New > "DWORD (32bit Value)"

   b. Name the key "TdrDelay"

   c. Double-click on "TdrDelay" key, make it a Decimal, and set its value to some "large" value you feel comfortable with. A conservative value may be 60 (sec), but the higher the better for potentially long-running GPU calculations.

4. Reboot your system for settings to take effect. In some cases, the TdrDelay value can be changed automatically in some cases if you update your OS.
