Abstract

A transactional memory system coalesces two outermost transactions in a transactional memory environment. A processor of the transactional memory system executes a first transaction begin instruction of a first outermost transaction and processes the first transaction. Based on encountering a first transaction end instruction of the first outermost transaction, the processor determines whether the first transaction is to-be coalesced with a second outermost transaction. Based on a determination that the first outermost transaction is to-be coalesced, the processor does not commit store data of the first outermost transaction to memory prior to processing the second outermost transaction. Based on encountering a second transaction begin instruction of the second outermost transaction, the processor processes the second transaction. Based on encountering a second transaction end instruction of the second outermost transaction, the processor commits the store data of the coalesced first outermost transaction and second outermost transaction to memory.
