Abstract

We present an analytical performance modeling approach for concurrency control al- gorithms in the context of Software Transactional Memories (STMs). Unlike existing ap- proaches, we consider a realistic execution pattern where each thread alternates the exe- cution of transactional and non-transactional code portions. Also, our model captures dy- namics related to the execution of both transactional read/write memory accesses and non- transactional operations, even when they occur within transactional contexts. Further, we rely on a detailed approach explicitly capturing key parameters, such as the execution cost of transactional and non-transactional operations, as well as the cost of begin, commit and abort operations. The proposed modeling methodology is general and extensible, lending itself to be easily specialized to capture the behavior of different STM concurrency control algorithms. In this work we specialize it to model the performance of Commit-Time-Locking algorithms, which are currently used by several STM systems. Copyright © 2010, Unisys Corporation. All rights reserved.
