Enhancing Job Scheduling of an Atmospheric Intensive Data Application

Nowadays, e-Science applications involve great deal of data to have more accurate analysis. One of its application domains is the Radio Occultation which manages satellite data. Grid Processing Management is a physical infrastructure geographically distributed based on Grid Computing, that is implemented for the overall processing Radio Occultation analysis. After a brief description of algorithms adopted to characterize atmospheric profiles, the paper presents an improvement of job scheduling in order to decrease processing time and optimize resource utilization. Extension of grid computing capacity is implemented by virtual machines in existing physical Grid in order to satisfy temporary job requests. Also scheduling plays an important role in the infrastructure that is handled by a couple of schedulers which are developed to manage data automaticall

Proceedings of the 5th International Workshop on Reconfigurable Communication-centric Systems on Chip 2010 - ReCoSoC\u2710 - May 17-19, 2010 Karlsruhe, Germany. (KIT Scientific Reports ; 7551)

ReCoSoC is intended to be a periodic annual meeting to expose and discuss gathered expertise as well as state of the art research around SoC related topics through plenary invited papers and posters. The workshop aims to provide a prospective view of tomorrow\u27s challenges in the multibillion transistor era, taking into account the emerging techniques and architectures exploring the synergy between flexible on-chip communication and system reconfigurability

Trusted Execution Development: Designing a Secure, High-Performance Remote Attestation Protocol

Intel Software Guard Extensions (SGX) are a Trusted Execution Environment (TEE) technology that allow programs to protect execution process and data from other processes on the platform. We propose a method to combine SGX attestation with Transport Layer Security (TLS). Doing so will combine guarantees about the program, runtime environment, and machine identity into a normal TLS handshake. We implemented a basic server using SGX/TLS and provide performance details and lessons learned during development

Development of Online Course System and an Open Access Online Repository

This Project was divided in to two phases: the first phase comprising of development of an online course system for the institute with the help of moodle. Moodle( modular object oriented dynamic learning environment) is an open source software package for producing internet-based courses and web sites. It's an ongoing development project designed to support a social Constructionist framework of education. Moodle is provided freely as Open Source software (under the GNU Public License). Basically this means Moodle is copyrighted, but that we have additional freedoms of improvising the source code. The 2nd Phase of the project was that of deployment of an open access online repository system using E-prints. EPrints is an open source software package for building open access repositories that are compliant with the Open Archives Initiative Protocol for Metadata Harvesting. It shares many of the features commonly seen in Document Management systems, but is primarily used for institutional repositories and scientific journals. EPrints has been developed at the University of Southampton School of Electronics and Computer Science and released under a GPL license

Building a High Performance Cluster through Computer Reuse

The goal of this MQP was to use outdated commodity PCs to build a cluster computer capable of being used for computationally intensive research. Traditionally, PCs are recycled after being taken out of use during a refresh cycle. By using open source software and minimal hardware modifications these PCs can be configured into a cluster that approaches the performance of state-of-the-art cluster computers. In this paper, we present the system setup, configuration, and validation of the WOPPR cluster computer
