硬件系统中日益增加的异构性为开发人员提供了许多机会,可以向系统添加更多功能和计算能力。因此,现代数据库系统将需要能够适应各种各样的异构体系结构。虽然将单个操作符移植到加速器架构是很好理解的,但整个数据库系统需要一种更通用的方法。在以前的工作中,我们提出了一个通用的硬件无关的数据库系统,其中的运营商可以在主处理器上执行,以及大量的加速器架构。然而,要实现完全异构的查询处理,放置决策需要的数据库操作员。我们增强了所提出的系统与异质性感知运营商的位置(HOP),采取了重要的一步,设计一个数据库系统,可以有效地利用高度异构的硬件环境。在本演示中,我们将重点关注放置集成方面,并展示最终的数据库系统。
The increasing heterogeneity in hardware systems gives developers many opportunities to add more functionality and computational power to the system. As a consequence, modern database systems will need to be able to adapt to a wide variety of heterogeneous architectures. While porting single operators to accelerator architectures is well-understood, a more generic approach is needed for the whole database system. In prior work, we presented a generic hardware-oblivious database system, where the operators can be executed on the main processor as well as on a large number of accelerator architectures. However, to achieve fully heterogeneous query processing, placement decisions are needed for the database operators. We enhance the presented system with heterogeneity-aware operator placement (HOP) to take a major step towards designing a database system that can efficiently exploit highly heterogeneous hardware environments. In this demonstration, we are focusing on the placement-integration aspect as well as presenting the resulting database system.
