after running awhile this problem occur :
"cudaSafeCall() failed at D:/PROGRAMMING/VisualStudioProjects/KeyHunt-Cuda-GIT-2017/KeyHunt-Cuda/KeyHunt-Cuda/GPU/GPUEngine.cu:686 : an illegal memory access was encountered'.
then stop,.. why is this? is it because lack of virtual memory?
Did you change CCAP value to match your GPU CCAP?
