The exponential growth of the Internet, cou led with the increasing populari of dynamically generated content on the WorlJWide Web, has created the nee2 for more and faster Web servers capable of serving the over 100 million Internet users. Server clustering has emerged as a promising technique to build scalable Web servers. In this article we examine the seminal work, early products, and a sam...

ProMiR is a web-based service for the prediction of potential microRNAs (miRNAs) in a query sequence of 60-150 nt, using a probabilistic colearning model. Identification of miRNAs requires a computational method to predict clustered and nonclustered, conserved and nonconserved miRNAs in various species. Here we present an improved version of ProMiR for identifying new clusters near known or unk...

Cluster-based Web server systems have become a major means to hosting e-commerce sites. In this paper, we link the issue of resource partitioning scheme with the pricing strategy in a Service-Level-Agreement (SLA) and analyze the problem of maximizing the revenues attained in the hosting of a ecommerce site with a SLA contract by optimally partitioning the server resources among all supported s...

Cluster systems are leading architectures for building popular Web sites that have to guarantee scalable services when the number of accesses grows exponentially. The most common Web cluster systems consist of replicated back-end and Web servers, and a Web switch that routes client requests among the nodes. In this paper, we propose a new scheduling policy, namely Multi-Class Round Robn (MCRR),...
