An efficient approach to achieve compositionality using optimized multi-version object based transactional systems

In the modern era of multi-core systems, main aim is to utilize cores properly. This utilization can be done by concurrent programming. But developing a flawless and well-organized program difficult. Software Transactional Memory Systems (STMs) are convenient programming interface which assist programmer access shared memory concurrently without worrying about consistency issues. Many STMs available in literature execute read/write primitive operations on buffers. We represent them as Read-Write or RWSTMs. Whereas, there exists some work higher level operations. refer these Object Based OSTMs. The databases RWSTMs say that maintaining multiple versions ensures greater concurrency. So, this paper proposes notion Optimized Multi-version OPT-MVOSTMs encapsulates idea OSTMs harness concurrency efficiently.
