Optimization of Reading Data via Classified Block Access Patterns in File Systems
IEEE Access, 2016 This paper proposes a novel mechanism to model a time series of block accesses for profiling block access patterns, to intentionally direct block data prefetching.

Implications of NVM Based Storage on Memory Subsystem Management
Applied Sciences, 2020 Recently, non-volatile memory (NVM) has advanced as a fast storage medium, and legacy memory subsystems optimized for DRAM (dynamic random access memory) and HDD (hard disk drive) hierarchies need to be revisited.

Implementing Performance Competitive Logical Recovery [PDF]
, 2010 New hardware platforms, e.g. cloud, multi-core, etc., have led to a reconsideration of database system architecture. Our Deuteronomy project separates transactional functionality from data management functionality, enabling a flexible response to ...

Analysis of Buffer Starvation with Application to Objective QoE Optimization of Streaming Services [PDF]
, 2013 Our purpose in this paper is to characterize buffer starvations for streaming services. The buffer is modeled as an M/M/1 queue, plus the consideration of bursty arrivals.

A performance model of speculative prefetching in distributed information systems
, 1999 Previous studies in speculative prefetching focus on building and evaluating access models for the purpose of access prediction. This paper investigates a complementary area which has been largely ignored, that of performance modelling.

ACM Transactions on Architecture and Code Optimization, 2017 In multi-core systems, an application’s prefetcher can interfere with the memory requests of other applications using the shared resources, such as last level cache and memory bandwidth. In order to minimize prefetcher-caused interference, prior mechanisms have been proposed to dynamically control prefetcher aggressiveness at runtime.

Optimal Error Correcting Delivery Scheme for Coded Caching with Symmetric Batch Prefetching
, 2017 Coded caching is used to reduce network congestion during peak hours. A single server is connected to a set of users through a bottleneck link, which generally is assumed to be error-free.

Prefetching Scheme for Massive Spatiotemporal Data in a Smart City
International Journal of Distributed Sensor Networks, 2016 Employing user access patterns to develop a prefetching scheme can effectively improve system I/O performance and reduce user access latency. For massive spatiotemporal data, traditional pattern mining methods fail to directly reflect the spatiotemporal ...

An Active Prefetch Filtering Schemes using Exclusive Prefetch Cache [PDF]
The KIPS Transactions:PartA, 2005 Memory reference instruction caused by cache miss is the critical factor that limits the processing power of processor. Cache prefetching technique is an effective way to reduce the latency due to memory access. However, excessively aggressive prefetch leads to cache pollution and finally to cancel out the advantage of prefetch.
