Was running two GFN-21 tasks: on the CPU (https://www.primegrid.com/result.php?resultid=1042083057) and on the GPU (https://www.primegrid.com/result.php?resultid=1042374359).
A BSOD happened.
The GPU task then continued and verified successfully while the CPU one continued but was stated to be invalid.
Looking for a general advice on what I should have done in this case.
Also wondering if CPU and GPU implementations have different "restart from last good checkpoint" approaches and if there are any command-line options to control the behavior.
