We evaluate the performance of distributed file systems (DFS) under the IO load produced by enterprise applications. The evaluation is carried out using a trace-based approach that allows for recording file system accesses of an application and re-playing the trace on an arbitrary file systems under test. This method avoids the overhead that is associated with installing and maintaining complex...

Emerging network technologies offer new design choices for performing traffic engineering and management, while introducing challenges for existing protocol control mechanisms. There is a tension between new hop-by-hop capabilities and existing end-to-end mechanisms. In this paper we examine one such capability, the Load-Reactive Link (LRL), which has capacity that can be automatically varied i...

Isosurface extraction is a common technique applied in scientific visualization. Increasing sizes of volumes over which isosurfacing is to be applied combined with increasingly hierarchical parallel architectures present challenges for efficiently distributing isosurfacing work loads. We propose a technique that, with a modest amount of preprocessing, efficiently distributes isosurfacing load t...

The present work is an experimental account of the way in which several machine settings, particularly cylinder knock-over and dial-height, influence fabric dimensions, course length, bending behavior and load extension of fabrics produced on a circular knitting machine. The results show that there are certain optimum settings for such variables as knock-over depth and dial-height for producing...

ORK-LOAD CONTROL FACTORS in clinical laboratories are not available in the literature. Business engineering and manpower-study methods are not readily applicable to laboratory work in which varied human elements exist. The remarkable variety of methods, choice of technics, personal viewpoints, lack of contacts, and few chances for direct comparison with the work of others in the field also make...
