Cuda Programming Erros on udacity of Intro Parallel programming course.

Hello, I’m new to cuda programming. When I learn cuda programming on udacity course, I encountered a problem when I write radix sort. here’s my answer on stackoverflow, could anyone can help me?

I suppose I found the bug in it.

Good, next time, be sure you are using the right syntax and non- depreciated sm version.

Hi zhangyule, can you still access to udacity cs344 now?
I tried to access to it, but failed.
“Enroll today”
Then it will goto “Courses and Nanodegree Programs”, but not found cs344.
