摘要

在多核时代,利用线程级并行性是至关重要的。事务通过极大地简化多线程编程模型,使程序员能够公开这种并行性。虚拟化事务(在空间和时间上不受限制)是可取的,因为它们可以增加事务使用的范围,从而进一步简化程序员的工作。然而,硬件支持对于支持无界事务的有效执行至关重要。在本文中,我们引入基于页面的事务性内存来支持无界事务。我们将事务簿记与虚拟内存系统相结合,以支持快速的事务冲突检测、提交、中止,并维护事务的推测数据。

Unbounded page-based transactional memory
Exploiting thread level parallelism is paramount in the multicore era. Transactions enable programmers to expose such parallelism by greatly simplifying the multi-threaded programming model. Virtualized transactions (unbounded in space and time) are desirable, as they can increase the scope of transactions' use, and thereby further simplify a programmer's job. However, hardware support is essential to support efficient execution of unbounded transactions. In this paper, we introduce Page-based Transactional Memory to support unbounded transactions. We combine transaction bookkeeping with the virtual memory system to support fast transaction conflict detection, commit, abort, and to maintain transactions' speculative data.
