— Syllabus — Software Transactional Memory
“Transactional memory” means that, instead of using explicit locks to protect from data races (like the Java synchronized construct), a programmer could declare a block of code atomic and rely on the underlying software and hardware system to ensure that code within the block executes as if atomic. The transactional memory system might use any of several concurrency control protocols, with some...
متن کاملDistributed Software Transactional Memory
This report describes an implementation of a distributed software transactional memory (DSTM) system in PLT Scheme. The system is built using PLT Scheme’s Unit construct to encapsulate the various concerns of the system, and allow for multiple communication layer backends. The front-end API exposes true parallel processing to PLT Scheme programmers, as well as cluster-based computing using a sh...
متن کاملAdaptive Software Transactional Memory
Software Transactional Memory (STM) is a generic synchronization construct that enables automatic conversion of correct sequential objects into correct nonblocking concurrent objects. Recent STM systems, though significantly more practical than their predecessors, display inconsistent performance: differing design decisions cause different systems to perform best in different circumstances, oft...
متن کاملSnapshots and software transactional memory
One way that software transactional memory implementations attempt to reduce synchronization conflicts among transactions is by supporting different kinds of access modes. One such implementation, Dynamic Software Transactional Memory (DSTM), supports three kinds of memory access: WRITE access, which allows an object to be observed and modified, READ access, which allows an object to be observe...
