Matlab-PCT with CUDA Programming: Synchronization

Since pointer operations were needed, I used "__syncthreads();" in my CUDA code and it seemed that matlab did not recognize this and I got a wrong result. It was not flaws in my code because when I put two of the synchronizing command together, the result became better. The more, the better.

So, does Matlab-PCT recognize "__syncthreads();", or is it that this command does not synchronize all the threads in matlab? And what is the efficient way of synchronizing the threads in Matlab linked CUDA?

MATLAB and PCT don't change the behavior of __syncthreads() in your CUDA code. Can you say more about your kernel, how it uses __syncthreads(), and how it is being called from MATLAB?
