Volunteer Computing Different Grids for Different Needs
From the Web to the Grid How did the Grid start? • Name “Grid” chosen by analogy with electric power grid (Foster and Kesselman 1997) • Vision: plug-in computer for processing power just like plugging in toaster for electricity. • Concept has been around for decades (distributed computing, metacomputing) • Key difference with the Grid is to realise the vision on a global scale. From the Web to the Grid – 2007 HST 2011: Grids and Volunteer Computing Different Grids for different needs There is as yet no unified Grid, like there is a single web. Rather there are many Grids for many applications: • Enterprise Grids link together PCs within one company. • Volunteer computing links together public computers. • Scientific Grids link together major computing centres. • Latest trend federates national Grids into global Grid infrastructure. • High Energy Physics is a driving force for this. HST 2011: Grids and Volunteer Computing The LHC data challenge 1 Megabyte (1MB) • 40 million bunch collisions per second A digital photo 1 Gigabyte (1GB) = 1000MB • After filtering, ~100 collisions of 5GB = A DVD movie interest per second per detector 1 Terabyte (1TB) = 1000GB World annual book production • > 1 Megabyte of data per collision 1 Petabyte (1PB) recording rate > 1 Gigabyte/sec = 1000TB Annual production of one LHC experiment 10 • 10 collisions recorded each year 1 Exabyte (1EB) stored data ~15 Petabytes/year = 1000 PB 3EB = World annual information production …for more than 10 years HST 2011: Grids and Volunteer Computing Data Storage for the LHC Balloon (30 Km) • LHC data correspond to about 20 million CDs each year!

Spin-Off Successes of SETI Research at Berkeley
**FULL TITLE** ASP Conference Series, Vol. **VOLUME**, c **YEAR OF PUBLICATION** **NAMES OF EDITORS** Spin-Off Successes of SETI Research at Berkeley K. A. Douglas School of Physics, University of Exeter, Exeter, United Kingdom D. P. Anderson, R. Bankay, H. Chen, J. Cobb, E.J. Korpela, M. Lebofsky, A. Parsons, J. Von Korff, D. Werthimer Space Sciences Laboratory, University of California Berkeley, Berkeley CA, USA 94720 Abstract. Our group contributes to the Search for Extra-Terrestrial Intelligence (SETI) by developing and using world-class signal processing computers to analyze data collected on the Arecibo telescope. Although no patterned signal of extra-terrestrial origin has yet been detected, and the immediate prospects for making such a detection are highly uncertain, the SETI@home project has nonetheless proven the value of pursuing such research through its impact on the fields of distributed computing, real-time signal pro- cessing, and radio astronomy. The SETI@home project has spun off the Center for Astronomy Signal Processing and Electronics Research (CASPER) and the Berkeley Open Infrastructure for Networked Computing (BOINC), both of which are responsi- ble for catalyzing a smorgasbord of new research in scientific disciplines in countries around the world. Futhermore, the data collected and archived for the SETI@home project is proving valuable in data-mining experiments for mapping neutral galatic hy- drogen and for detecting black-hole evaporation. 1 The SETI@home Project at UC Berkeley SETI@home is a distributed computing project harnessing the power from millions of volunteer computers around the world (Anderson 2002). Data collected at the Arecibo radio telescope via commensal observations are filtered and calibrated using real-time signal processing hardware, and selectable channels are recorded to disk. -

Joshi Supercomputer Education and Research Centre INDIAN INSTITUTE OF SCIENCE BANGALORE – 560 012, INDIA August 2007 Acknowledgments First of all I would like to extend my sincere thanks to my research supervisor Dr. Sathish Vadhiyar for his constant guidance and support during the entire period of my post-graduation at IISc. He was always approachable, supportive and ready to help in any sort of problem. I am very thankful to him for being extremely patient and understanding about the silly mistakes that I had made. Under his guidance I learned to approach problems in an organized manner and set realistic goals for my research. I thank him for his extreme patience and excellent technical guidance in writing and presenting research. Finally, he was and continues to be my role model for his hard work and passion for research. I am also thankful to Dr. Nagasuma Chandra, Dr. Debnath Pal from S.E.R.C. and Dr. Narendra Dixit from Chemical Engineering department for their very useful and interesting insights into the biological domain of our research. I am also thankful to all the faculty of S.E.R.C. for always inspiring us with their motivational talks. I would like to mention the names of my colleagues Sandip, Sanjay, Rakhi, Sundari, Antoine and Roshan for making their technical and emotional support.

An Investigation Into Citizen Cyberscience
When Scientists Meet the Public: An Investigation into Citizen Cyberscience Peter Darch Corpus Christi College University of Oxford A dissertation submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy Michaelmas Term 2011 Peter Darch Corpus Christi College When Scientists Meet the Public: An Investigation into Citizen Cyberscience Abstract Citizen Cyberscience Projects (CCPs) are projects mediated through the Internet, in which teams of scientists recruit members of the public (volunteers) to assist in scientific research, typically through the processing of large quantities of data. This thesis presents qualitative ethnographic case studies of the communities that have formed around two such projects, climateprediction.net and Galaxy Zoo. By considering these social actors in the broader contexts in which they are situated (historical, institutional, social, scientific), I discuss the co-shaping of the interests of these actors, the nature of the relationships amongst these actors, and the infrastructure of the projects and the purposes and nature of the scientific work performed. The thesis focusses on two relationships in particular. The first is that between scientists and volunteers, finding that, although scientists in both projects are concerned with treating volunteers with respect, there are nevertheless considerable differences between the projects. These are related to a number of interconnecting factors, including the particular contexts in which each project is embedded, the nature of the scientific work that volunteers are asked to undertake, the possibilities and challenges for the future development of the projects as perceived by the scientists, and the tools at the disposal of the respective teams of scientists for mediating relationships with volunteers. -

Deploying and Maintaining a Campus Grid at Clemson University A Thesis Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Masters Computer Science by Dru Sepulveda May 2009 Accepted by: Sebastien Goasguen, Committee Chair Mark Smotherman Steven Stevenson Abstract Many institutions have all the tools needed to create a local grid that aggregates commodity compute resources into an accessible grid service, while simultaneously maintaining user satisfaction and system security. In this thesis, the author presents a three-tiered strategy used at Clemson University to deploy and maintain a grid infrastructure by making resources available to both local and federated remote users for scientific research. Using this approach virtually no compute cycles are wasted. Usage trends and power consumption statistics collected from the Clemson campus grid are used as a reference for best-practices. The loosely-coupled components that comprise the campus grid work together to form a highly cohesive infrastructure that not only meets the computing needs of local users, but also helps to fill the needs of the scientific community at large.
