Trustable Worst-Case Execution-Time (WCET) bounds are a necessary component for the construction and verification of hard real-time computer systems. Deriving such bounds for contemporary hardware/software systems is a complex task. The single-path ...

Trustable Worst-Case Execution-Time (WCET) bounds are a necessary component for the construction and verification of hard real-time computer systems. Deriving such bounds for contemporary hardware/software systems is a complex task. The single-path ...

Mobile network operators are expected to face significant traffic increase in the upcoming years. One alternative method is to intelligently move transmissions to times of network underutilization, either on 3G/4G or by offloading to WiFi. Video content,...

We present an integrated prefetching and caching proxy, termed iPac, for HTTP-based adaptive video streaming services like Netflix and YouTube. The challenge we address is maximizing the byte-hit ratio for proxies through prefetching in the context of ...

As multicore and many-core architectures evolve, their memory systems are becoming increasingly more complex. To bridge the latency and bandwidth gap between the processor and memory, they often use a mix of multilevel private/shared caches that are ...

In this work we comparatively present and evaluate different prediction techniques used to anticipate and prefetch web pages and files accessed via browsers. The goal is to reduce the delays necessary to load the web pages and files visited by the ...

Prefetching control is a vital operation for the On-demand interactive systems where the instantaneous response is the crucial factor for the system success. The controller in such type of interactive system operates in an uncertain environment and ...

Mobile users often suffer from a slow page loading time due to intermittently connected wireless networks and increasing size of mobile Web pages. Although existing approaches of prefetching and caching are widely used to reduce the browsing latency, ...

Hardware prefetchers are commonly used to hide and tolerate off-chip memory latency. Prefetching techniques in the literature are designed for multiple independent sequential applications running on a multicore system. In contrast to multiple ...

Caching query results is an efficient technique for Web search engines. Admission policy can prevent infrequent queries from taking space of more frequent queries in the cache. In this paper we present two novel admission policies tailored for query ...

Media streaming in automotive environments is becoming more important with the proliferation of 3G/4G technologies and the general demand for consuming Internet content in cars. Especially the rising popularity of Music on Demand and Media Cloud Storage ...

Past work has shown that disk prefetching can be an effective technique for improving the performance of disk bound workloads. However, the performance gains are highly dependent on selecting a prefetch size that is appropriate for a specific system and ...

New trends in storage industry suggest that in the near future a majority of the hard disk drive-based storage subsystems will be replaced by solid state drives (SSDs). Database management systems can substantially benefit from the superior I/O ...

In this paper, we provide the authors? retrospective analysis of the paper "Bloom Filtering Cache Misses for Accurate Data Speculative and Prefetching" which was published in the proceedings of 2002 International Conference on Supercomputing.

The paper introduces and evaluates a technique, referred to as runahead, that prefetches instructions and data into the L1 caches on cache misses. The results of the experiments reported in the paper show that the CPI of a simple in-order pipeline could ...

The ideas of compiler-generated prefetching were first proposed in the late 80's. Two main research directions were pursued, both addressed prefetching for loop-based applications containing arrays with regular access patterns. Our approach assumed a ...

Many popular, professionally-written smartphone apps today prefetch large amounts of network data to improve performance. However, the typical user may not use all of this network data. When a user is on a limited or pay-per-byte cellular data plan, ...

Generations of computer programmers are taught to prefetch network objects in computer science classes. In practice, prefetching can be harmful to the user's wallet when she is on a limited or pay-per-byte cellular data plan. Many popular, ...

The Hybrid Memory Cube (HMC) is a 3D-stacked DRAM architecture designed for substantially improved memory bandwidth. In particular, its I/O interface achieves up to 320 GB/s of external bandwidth through high-speed serial links. However, it comes at a ...

Hardware data prefetch engines are integral parts of many general purpose server-class microprocessors in the field today. Some prefetch engines allow users to change some of their parameters. But, the prefetcher is usually enabled in a default ...
