Abstract
Method and apparatus are provided for a synchronizing execution of a plurality of threads on a multi-threaded processor. Each thread is provided with a number of synchronization points corresponding to points where it is advantageous or preferable that execution should be synchronized with another thread. Execution of a thread is paused when it reaches a synchronization point until at least one other thread with which it is intended to be synchronized reaches a corresponding synchronization point. Execution is subsequently resumed. Where an executing thread branches over a section of code which included a synchronization point then execution is paused at the end of the branch until the at least one other thread reaches the synchronization point of the end of the corresponding branch.
