Tuning Starfish

چکیده
STARFISH is a parallel le system simulator we built for our research into the concept of disk directed I O In this report we detail steps taken to tune the le systems supported by STARFISH which include a traditional parallel le system with caching and a disk directed I O system In particular we now support two phase I O use smarter disk scheduling increased the maximumnumber of outstanding requests that a compute processor may make to each disk and added gather scatter block transfer We also present results of the experiments driving the tuning e ort

MapReduce Programming and Cost-based Optimization? Crossing this Chasm with Starfish
MapReduce has emerged as a viable competitor to database systems in big data analytics. MapReduce programs are being written for a wide variety of application domains including business data processing, text analysis, natural language processing, Web graph and social network analysis, and computational science. However, MapReduce systems lack a feature that has been key to the historical succes...
متن کاملPStorM: Profile Storage and Matching for Feedback-Based Tuning of MapReduce Jobs
The MapReduce programming model has become widely adopted for large scale analytics on big data. MapReduce systems such as Hadoop have many tuning parameters, many of which have a significant impact on performance. The map and reduce functions that make up a MapReduce job are developed using arbitrary programming constructs, which make them black-box in nature and therefore renders it difficult...
متن کاملA What-if Engine for Cost-based MapReduce Optimization
The Starfish project at Duke University aims to provide MapReduce users and applications with good performance automatically, without any need on their part to understand and manipulate the numerous tuning knobs in a MapReduce system. This paper describes the What-if Engine, an indispensable component in Starfish, which serves a similar purpose as a costing engine used by the query optimizer in...
متن کاملP 125: Treatment of Multiple Sclerosis with Mesenchymal Cells Starfish
Arm grooves of star-fish have mesenchymal stem cells derived from adipose tissue cell. Widespread studies have shown that stem cells derived from adipose-derived mesenchymal stem cell from bone marrow have many similarities in terms of the ability to differentiate into a variety of tissues. Most of the animals live in warm and shallow waters and the waters of this feature is that it is low in d...
متن کاملEvaluation of the effects of diethyl ether and methanol extracts of carpet anemone (Sarcophyton spp.) and starfish (Pentaceraster spp.) on E. coli and Bacillus subtilis bacteria
Marine environment is the main source of natural bioactive products whose chemical-structural properties are not similar with other natural products of plants and other inland organisms. The present study was carried out to evaluate antibiotic properties of diethyl ether and methanol extracts of two marine species including starfish and carpet anemone. The samples of starfish and carpet anemone...
