Software and architecture support for the bulk multicore
Research on transactional memory began as a tool to improve the experience of programmers working on parallel code. Just as transactions in databases, it was the job of the runtime to detect any conflicts between parallel transactions and rollback the ones that needed to be re-executed, leaving the …

Improving Performance of Highly-Programmable Concurrent Applications by Leveraging Parallel Nesting and Weaker Isolation Levels
… in the experiments run. Another method to alter transactional execution and boost performance is to relax the rules of visibility for parallel operations (known as their isolation). Depending on the application, correctness is not broken even if some transactions see external work that may later …

Extracting Parallelism from Legacy Sequential Code Using Transactional Memory
… for custom hardware support; using optimistic execution or relying on conservative decisions; online, offline or both; and the level of source code exposure. Transactional Memory (TM) has emerged as a powerful concurrency control abstraction. TM simplifies parallel programming to the level of …

Designing, Modeling, and Optimizing Transactional Data Structures
Transactional memory (TM) has emerged as a promising synchronization abstraction for multi-core architectures. Unlike traditional lock-based approaches, TM shifts the burden of implementing threads synchronization from the programmer to an underlying framework using hardware (HTM) and/or software …
