The problem is that Visual Studio 2010 says: … WebJan 15, 2013 · CUDA provides a simple barrier synchronization primitive, syncthreads. A thread’s execution can only proceed past syncthreads after all threads in its block have executed syncthreads. You can avoid the race condition described above by calling syncthreads after the store to shared memory and before any threads load from shared …
