摘要:

许多现代和新兴的应用程序必须处理越来越大的数据量。不幸的是,流行的计算范例并没有被设计为有效地处理这样的大规模数据:在内存子系统和CPU之间移动这些数据的能量和性能成本现在占了计算的总成本的主导地位。这迫使系统架构师和设计师从根本上重新思考如何设计计算机。内存处理(PIM)是一种计算范例,通过将计算引入数据来避免大多数数据移动成本。现代存储器系统中的新机会使得能够在存储器子系统内执行不同程度的处理的架构成为可能。然而,构建PIM架构必须解决许多实际的系统级问题,包括使工作负载和程序员能够轻松地利用PIM。本文研究了实现PIM架构的实际构建和广泛采用的三个关键领域。首先,我们描述了我们在系统地识别PIM在实际应用中的机会方面的工作,并量化了流行的新兴应用的潜在收益(例如,机器学习、数据分析、基因组分析)。其次,我们的目标是解决几个关键问题,这些程序的PIM架构。第三,我们描述了广泛采用PIM仍然面临的挑战。

英文摘要:

Many modern and emerging applications must process increasingly large volumes of data. Unfortunately, prevalent computing paradigms are not designed to efficiently handle such large-scale data: the energy and performance costs to move this data between the memory subsystem and the CPU now dominate the total costs of computation. This forces system architects and designers to fundamentally rethink how to design computers. Processing-in-memory (PIM) is a computing paradigm that avoids most data movement costs by bringing computation to the data. New opportunities in modern memory systems are enabling architectures that can perform varying degrees of processing inside the memory subsystem. However, there are many practical system-level issues that must be tackled to construct PIM architectures, including enabling workloads and programmers to easily take advantage of PIM. This article examines three key domains of work towards the practical construction and widespread adoption of PIM architectures. First, we describe our work on systematically identifying opportunities for PIM in real applications, and quantify potential gains for popular emerging applications (e.g., machine learning, data analytics, genome analysis). Second, we aim to solve several key issues on programming these applications for PIM architectures. Third, we describe challenges that remain for the widespread adoption of PIM.
