Software Transactional Memory implementing Transactional Locking 2 (TL2) algorithm.

This repository contains an implementation of a Software Transactional Memory according to the description of Transactional Locking 2 (TL2) algorithm (Dice et. al) using C11 atomics.

It was developed by Manos Chatzakis (emmanouil.chatzakis@epfl.ch) at EPFL in December 2023.

Overview

The implementation of TL2 manages to outperform the corresponding coarse-grained pthread lock implementation of transactional programming, achieving approximately 2.5x speedup.
