WebFountain is a platform for very large-scale text analytics applications that allows uniform
access to a wide variety of sources. It enables the deployment of a variety of document-level …

Three-dimensional integration enables stacking memory directly on top of a microprocessor,
thereby significantly reducing wire delay between the two. Previous studies have examined …

Belady's algorithm is optimal but infeasible because it requires knowledge of the future. This
paper explains how a cache replacement algorithm can nonetheless learn from Belady's …

This paper presents Voyager, a novel neural network for data prefetching. Unlike previous
neural models for prefetching, which are limited to learning delta correlations, our model can …

Many multi-core processors employ a large last-level cache (LLC) shared among the
multiple cores. Past research has demonstrated that sharing-oblivious cache management …

DRAM latency continues to be a critical bottleneck for system performance. In this work, we
develop a low-cost mechanism, called Charge Cache, that enables faster access to recently …

Timing-accurate full-system multiprocessor simulations can take years because of
architecture and application complexity. Statistical sampling makes simulation-based …

This paper introduces the Irregular Stream Buffer (ISB), a prefetcher that targets irregular
sequences of temporally correlated memory references. The key idea is to use an extra level …

Hardware security has recently re-surfaced as a first-order concern to the confidentiality
protections of computing systems. Meltdown and Spectre introduced a new class of …

Ever-growing application data footprints demand faster main memory with larger capacity.
DRAM has been the technology choice for main memory due to its low latency and high …
