Degradation in parallel-disk rheometry

"Disk Cooling" in Parallel Disk Systems

Microfluidic rheometry

The development and growth of microfluidics has stimulated interest in the behaviour of complex liquids in microscale geometries and provided a rich platform for rheometric investigations of non-Newtonian phenomena at small scales. Microfluidic techniques present the rheologist with new opportunities for material property measurement and this review discusses the use of microfluidic devices to ...

A Multiprocessor Parallel Disk System Evaluation

This paper presents a Parallel Disk System (PDS) for general purpose multiprocessors, which provides support for conventional le systems and databases, as well as direct access for applications requiring high performance mass storage. We present a systematic method to characterize a parallel I/O system, using it to evaluate PDS and to identify an optimal PDS connguration. Several devices (singl...

Adaptive Disk Striping for Parallel Input/Output

As disk capacities continue to rise more rapidly than transfer rates, adaptive, redundant striping smoothly trades capacity for higher performance. We developed a fuzzy logic rule base for adaptive, redundant striping of les across multiple disks. This rule base is based on a queuing model of disk contention that includes le request sizes and disk hardware parameters. At low loads, the rule bas...

Selection algorithms for parallel disk systems

With the widening gap between processor speeds and disk access speeds, the I/O bottleneck has become critical. Parallel Disk Systems (PDS) have been introduced to alleviate this bottleneck. In this paper we present deterministic and randomized selection algorithms for parallel disk systems. The algorithms to be presented, in addition to being asymptotically optimal, have small underlying consta...
