HyflowCPP: A Distributed Transactional Memory Framework for C++

Abstract

We present the first ever distributed transactional memory (DTM) framework for distributed concurrency control in C++, called HyflowCPP. HyflowCPP provides distributed atomic sections, and pluggable support for policies for concurrency control, directory lookup, contention management, and networking. While there exists other DTM frameworks, they mostly target VM-based languages (e.g., Java, Scala). Additionally, HyflowCPP provides uniquely distinguishing TM features including strong atomicity, closed and open nesting, and checkpointing. Our experimental studies revealed that HyflowCPP achieves up to 6x performance improvement over state-of-the-art DTM frameworks.

Helenos: A Realistic Benchmark for Distributed Transactional Memory

“…The database is homogeneous in nature and can easily be distributed without incurring major modifications on the benchmark. Hence, the benchmark is often used to evaluate distributed TMs [19,14]. However, the benchmark has a limited range of transaction types, so it does not constitute a comprehensive evaluation tool.…”
