Abstract
Some described embodiments provide a system that performs stores in a memory system. During operation, the system receives a store for a first thread. The system then creates an entry for the store in a store queue for the first thread. While creating the entry, the system requests a store-mark for a cache line for the store, wherein the store-mark for the cache line indicates that one or more store queue entries are waiting to be committed to the cache line. The system then receives a response to the request for the store-mark, wherein the response indicates that the cache line for the store is store-marked. Upon receiving the response, the system updates a set of ordered records for the first thread by inserting data for the store in the set of ordered records, wherein the set of ordered records include store-marked stores for the first thread.
