Group Calls

void CCL_API group_start ()

group_start() starts a group call. You can use the group_start() function to initiate a group call operation which indicates that successive operations should not get blocked due to CPU synchronization.

void CCL_API group_end ()

group_end() ends a group call. The group_end() call returns when all the operations between group_start() and group_end() have been enqueued for execution, but not necessarily completed.
