As more threads added to execute the multi-threaded applications in the many-core era, memory contentions among different threads impose a severe challenge to both the programmability and performance. Existing studies show that Transactional Memory (TM) is able to solve the programmability problem and scale well on the fine-grained applications in the SPLASH-2 benchmark suite. As more investigations...
This paper addresses the issue of error detection in transactional memory, and proposes a new method of error detection based on redundant transaction (EDRT). This method creates a transaction copy for every transaction, and executes both original transactions and transaction copies on adequate processor cores, and achieves error detection by comparing the execution results. EDRT utilizes the data-versioning...
