Helenos：分布式事务存储器的现实基准
Helenos: A Realistic Benchmark for Distributed Transactional Memory
摘要：
transmittedmemory（TM）是一种并发控制方法，旨在使编写并行程序既有效又简单。该方法开始于非分布式多处理器系统，但在分布式系统中越来越流行，以大规模同步任务。效率和可扩展性是TM研究中的关键问题，因此性能基准测试是TM研究的重要组成部分。然而，尽管标准TM基准测试（如STAMP套件和STMBench7）可用并被广泛接受，但它们并不能很好地转换到分布式系统中。因此，可用于分布式TM系统的基准测试集非常有限，必须用微基准测试来填充，微基准测试的简单性和人工性质通常使它们无法提供信息或误导。因此，本文介绍了Helenos，一个现实的，复杂的，全面的分布式TM基准测试的基础上的问题，Facebook的收件箱，Cassandra分布式存储的应用程序。
英文摘要：
Transactional Memory (TM) is an approach to concurrency control that aims to make writing parallel programs both effective and simple. The approach is started in non-distributed multiprocessor systems, but is gaining popularity in distributed systems to synchronize tasks at large scales. Efficiency and scalability are often the key issues in TM research, so performance benchmarks are an important part of it. However, while standard TM benchmarks like the STAMP suite and STMBench7 are available and widely accepted, they do not translate well into distributed systems. Hence, the set of benchmarks usable with distributed TM systems is very limited, and must be padded with microbenchmarks, whose simplicity and artificial nature often makes them uninformative or misleading. Therefore, this paper introduces Helenos, a realistic, complex, and comprehensive distributed TM benchmark based on the problem of the Facebook inbox, an application of the Cassandra distributed store.
