Error: Assert failure at ...MemBankPortAssign.cpp(191)

Thank you very much.

You said you compiled fine, then I found the code I posted just removed one unused parameter (__local int *done). It was just this parameter caused this problem, although I did not know why. I have removed it from parameter list by just using it inside the kernel...

Then with your help, I successfully commented parts of my kernel out and found the lines of code that cause the "stuck". I am now trying to solve the "stuck".
