<p>Synchronization occurs when you call <strong>NvFlexMap()</strong> on a simulation buffer. To avoid making the CPU wait a long time for the GPU to finish its work it is good practice to call <strong>NvFlexMap()</strong> as far away from the <strong>NvFlexUpdateSolver()</strong> and <strong>NvFlexGet*()</strong> as possible. This gives the GPU enough time to finish its work so that the new data is ready for when you call <strong>NvFlexMap()</strong>.
