The tremendous increase in the size and heterogeneity of supercomputers makes it very difficult to predict the performance of a scheduling algorithm. In this context, relying on purely static scheduling and resource allocation strategies, that make scheduling and allocation decisions based on the dependency graph and the platform description, is expected to lead to large and unpredictable make spans...
Cloud Federation is one of the ideal solutions tothis random burst traffic problem. It focuses on 'borrowing'computing resources from foreign Clouds when home Cloud isabout to overloaded and 'leasing' resources to foreign Cloudswhen home Cloud is free. Considering crucial importance ofbusiness value for a Cloud provider, we need to perform somedynamic, reasonable and simple rules or mechanisms to...
Allocating computing resources to different tasks of surveillance systems has always been a big challenge. The problem becomes complicated when it requires dealing with real-time computation and decision making as the system cannot afford of processing all sensory feeds and execute computationally expensive algorithms. In multi-modal surveillance systems, real-time event detection and understanding...
Current cloud computing providers allocate their virtual machine (VM) instances via fixed price-based or auction-like mechanisms. However, these mechanisms have one limitation, they are all offline mechanisms, therefore they need to collect information and be invoked periodically. In this paper, we address this limitation by designing an online mechanism for dynamic provisioning and allocation of...
Consumer electronic products are increasingly becoming more open and flexible, which is achieved by replacing dedicate, single-function hardware components by software components running on programmable platforms. Scalable video algorithms (SVAs) using the novel principle of priority processing can guarantee real-time performance on these platforms even with limited resources. In this paper we describe...
We consider geographically distributed data centers forming a collectively managed cloud computing system, hosting multiple Service Oriented Architecture (SOA) based context aware applications, each subject to Service Level Agreements (SLA). The Service Level Agreements for each context aware application require the response time of a certain percentile of the input requests to be less than a specified...
Grid computing has emerged as a way to share geographically and organizationally distributed resources that may belong to different institutions or administrative domains. In this context, the scheduling and resource management is usually performed by a grid resource broker. The scheduling task consists of distributing the jobs among the different centers resources and the need to coordinate the grid...
