Recently energy consumption becomes an ever critical concern for both low-end and high-end storage servers and data centers. A majority of existing energy conservation solutions resort to multispeed disks. However, most of current server systems are ...

Code compression, initially conceived as an effective technique to reduce code size in embedded systems, today also brings advantages in terms of performance and energy consumption, due to an increase in the cache hit ratio. This paper proposes the design ...

Abstract¿In a distributed shared memory (DSM) multiprocessor, the processors cooperate in solving a parallel application by accessing the shared memory. The latency of a memory access depends on several factors, including the distance to the nearest ...

Thermal management of DRAM memory has become a critical issue for server systems. We have done, to our best knowledge, the first study of software thermal management for memory subsystem on real machines. Two recently proposed DTM (Dynamic Thermal Management) ...

Volume rendering has great potential for parallelization due to the tremendous number of computations necessary. Besides the enormous computational power needed, the memory interface is usually of crucial importance and frequently the bottleneck.This ...

Due to the increasing disparity between processor and main memory system cycle times, many computer systems are now incorporating two levels fo cache memory. Several studies have been done on the design and performance of second level caches, including ...

Efficient disk storage is a crucial component for many applications. The commonly used method of storing data on disk using file systems or databases incurs significant overhead which can be a problem for applications which need to frequently access ...

Abstract¿It is well known that compression and prediction are interrelated in that high compression implies good predictability, and vice versa. We use this correlation to find predictable properties of program behavior and apply them to appropriate ...

This paper presents a complete electrical analysis of Address decoder Delay Faults "ADFs” caused by resistive opens in RAMs. A classification between inter and intragate opens is made. A systematic way is introduced to explore the space of possible ...

The number of stored objects that should be targets of high throughput retrieval, such as multimedia stream objects, is increasing recently. To implement a high throughput storage system, striping technique using multiple disk drives are commonly used. ...

Interactive Poster Sessions serve as a valuable forum for presenting late-breaking research in computer-human interaction and receiving feedback from an interested body of viewers. The poster sessions held at this year's CHI '88 conference, May 15--19 ...

In this paper, laser Doppler vibrometry is used to study the motion of a femto slider in the vertical, pitch, roll, off-track and down-track direction due to slider–lubricant interactions. The change in slider dynamics is determined by comparing ...

In modern processors, the dynamic translation of virtual addresses to support virtual memory is done before or in parallel with the first-level cache access. As processor technology improves at a rapid pace and the working sets of new applications grow ...

A four-state magnetic random access memory (MRAM) and ternary content addressable memory (TCAM) were developed using epitaxial Co50Fe50/MgO/Co50Fe50 magnetic tunnel junctions with a tunnel magnetoresistance (TMR) ratio of 145% at room temperature (RT). ...

IBM thin-film tape heads have evolved from the ferrite-based heads first used in the IBM Model 3480 Tape Drive to the hard-disk-drive (HDD) technology flat-profile heads used in IBM Linear Tape-Open® (LTO®) products. This paper describes that transition ...
