Hi,

Can someone help me understand basic difference between the two: cudaThreadExit( void ) Vs cudaThreadSynchronize()

Thanks

cudaThreadExit() frees all memory you have allocated on the GPU, shuts down your GPU context.
cudaThreaSynchronize() waits until all previous asynchronous operations on the GPU have completed.
