基于任务迁移的租用复制内存局部性利用
Exploiting Locality in Lease-Based Replicated Transactional Memory via Task Migration
摘要：
我们提出了Lilac-TM，第一个本地感知的分布式软件传输内存（DSTM）的实现。Lilac-TM是一个完全分散的基于租赁的复制DSTM。它采用了一种新颖的自优化租赁循环方案，该方案基于动态确定是否将事务迁移到拥有其验证所需的租赁的节点，或者要求发起事务的节点获取这些租赁的思想。我们的实验评估表明，Lilac-TM为分布式工作负载提供了显着的性能增益，表现出数据本地性，而通常不会产生非数据本地工作负载的开销。
英文摘要：
We present Lilac-TM, the first locality-aware Distributed Software Transactional Memory (DSTM) implementation. Lilac-TM is a fully decentralized lease-based replicated DSTM. It employs a novel self- optimizing lease circulation scheme based on the idea of dynamically determining whether to migrate transactions to the nodes that own the leases required for their validation, or to demand the acquisition of these leases by the node that originated the transaction. Our experimental evaluation establishes that Lilac-TM provides significant performance gains for distributed workloads exhibiting data locality, while typically incurring no overhead for non-data local workloads.
