One embodiment of the present invention provides a system that facilitates concurrent non-transactional operations in a transactional memory system. During operation, the system receives a load instruction related to a local transaction. Next, the system determines if an entry for the memory location requested by the load instruction already exists in the transaction buffer. If not, the system allocates an entry for the memory location in the transaction buffer, reads data for the load instruction from the cache, and stores the data in the transaction buffer. Finally, the system returns the data to the processor to complete the load instruction. In this way, if a remote non-transactional store instruction is received during the transaction, the remote non-transactional store proceeds and does not cause the local transaction to abort.
