PhTM* - An Efficient Phase-Based Transactional Memory

This repository contains code used to obtain the experimental results published on:

• IPDS 2017 - Revisiting Phased Transactional Memory - DOI: https://doi.org/10.1145/3079079.3079094
• TPDS 2018 - The Case for Phase-Based Transactional Memory - DOI: https://doi.org/10.1109/TPDS.2018.2861712

The repository is organized as follows:

• PhTM-Star/ -- repository root.
  • allocators/ -- various memory allocators implementations we have tested.
  • htm/ -- small library to used HTM (HLE and RTM from Intel TSX. PorwerTM from IBM Power8).
  • microbench/ -- micro-benchmarks used in the evaluation.
  • msr/ -- small library to program Intel PMU and collect events of code blocks.
  • NOrec/ -- reduced version of RSTM library and Hybrid TM implementations (HyNOrec, RH_NOrec and HyCO).
  • phasedTM/ -- base implementation of Phased TM - PhTM (PROTOTYPE) and PhTM* (OPTIMIZED).
  • scripts/ -- utility scripts to compile, execute and plot results.
  • stamp/ -- STAMP benchmarks with dual-transactional code paths (a.k.a. FastPath and SlowPath).
  • tinySTM-1.0.4/ -- TinySTM 1.0.4 (not used in the experimental evaluation).
  • wlpdstm-20110815/ -- SwissTM (not used in the experimental evaluation).
