Abstract

A processing system includes a transactional memory, first and second resource managers, and a transaction manager for a concurrent program having a thread including an atomic transaction having a side-effecting action. The first resource manager is configured to enlist in the atomic transaction and manage a resource related to the side effecting action. The second resource manager is configured to enlist in the atomic transaction and manage the transaction memory. The transaction manager is coupled to the first and second resource managers and manager is configured to receive a vote from the first and second resource managers as to whether to commit the transaction. The side-effecting action is postponed until after the transaction commits or applied along with a compensating action to the side-effecting action.
