Abstract. In transactional memory, aborted transactions reduce performance, and waste computing resources. Ideally, concurrent execution of transactions should be optimally ordered...

Today's transactional memory systems implement the two-phase-locking (2PL) algorithm which aborts transactions every time a conflict happens. 2PL is a simple algorithm that pr...

This paper takes a step toward developing a theory for understanding aborts in transactional memory systems (TMs). Existing TMs may abort many transactions that could, in fact, co...
