FUR: Fast and Unlimited Reads on Persistent Memory Transactions

In this project we develop a Persistent Transactional Memory implementation for IBM's POWER8/POWER9. The starting point is POWER's HTM implementation with, Rollback-only transactions and suspend-resume. We currently emulate Persistent Memory using spin-loops and having in account the performance of Intel Optance DC PM Persistent Memory.

Setup

You will need a POWER8/POWER9 server. Clone the repo and run the tests (python ./tests_py/test_*.py).
