<p class="p">The application will be responsible for synchronizing access to shared objects. The application must ensure that any pending
operation which access the objects have completed before passing control to CUDA. This may be accomplished by issuing and
waiting for glFinish command on all GLcontexts (for OpenGL and likewise for other APIs). The application will be also responsible
for ensuring that any pending operation on the registered CUDA resource has completed prior to executing subsequent commands
in other APIs accesing the same memory objects. This can be accomplished by calling cuCtxSynchronize or cuEventSynchronize
(preferably).
