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!

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. -

Integrated Service and Desktop Grids for Scientific Computing
Integrated Service and Desktop Grids for Scientific Computing Robert Lovas Computer and Automation Research Institute, Hungarian Academy of Sciences, Budapest, Hungary [email protected] Ad Emmen AlmereGrid, Almere, The Nederlands [email protected] RI-261561 GRID 2010, DUBNA Why Desktop Grids are important? http://knowledgebase.ehttp://knowledgebase.e--irg.euirg.eu RI-261561 GRID 2010, DUBNA Introduction RI-261561 WP4 Author: Robert Lovas, Ad Emmen version: 1.0 Prelude - what do people at home and SME’s think about grid computing Survey of EDGeS project Questionnaires all across Europe Get an idea of the interest in people and SMEs to donate computing time for science to a Grid Get an idea of the interest in running a Grid inside an SME RI-261561 GRID 2010, DUBNA Survey amongst the General Public and SME’s RI-261561 GRID 2010, DUBNA Opinions about Grid computing RI-261561 GRID 2010, DUBNA Survey - Conclusions Overall: there is interest in Desktop Grid computing in Europe. However, that people are willing to change their current practice and say that they want to participate in Grid efforts does not mean that they are actually going to do that. Need to generate trust in the organisation that manages the Grid. People want to donate computing time for scientific applications, especially medical applications. They do not like to donate computing time to commercial or defense applications. People want feedback on the application they are running. No clear technical barriers perceived by the respondents: so this does not need much attention. Overall the respondents were rather positive about donating computing time for a Grid or about running applications on a Grid. -

A) Le programme Le programme BOINC a été créé par les universitaires de Berkeley (aux USA) afin d'aider la communauté scientifique. a) Histoire Le programme BOINC a été développé par la même équipe que celle qui créa en 1992 le programme SETI@Home. Ce programme, délaissé par le gouvernement, a pu survivre grâce à l'idée révolutionnaire du calcul partagé (Voir I)A)c) Comment ça marche? ). Après plusieurs années de bons et loyaux services, les programmeurs et chefs de ce projet ayant acquit un savoir faire unique dans le monde entier ont décidé de le partager avec d'autres projets afin que cette phénoménale puissance de calcul puisse profiter à d'autres. -
Projects on BONIC?
PRESENTED BY: SAJIN GEORGE PRIYANKA ANGADI Overview of the talk ● GRID and Cluster computing and what are their differences. ● What is BOINC and how it works ? ● Key features of BOINC. ● Power consumption and Energy consumption. ● Projects that are currently using BOINC ● BONIC interface and Client Software. ● How to setup your own BOINC. GRID COMPUTING A distributed computing environment that uses its own resources to handle computational tasks. Grid VS Cluster Loosely coupled Tightly coupled systems (Decentralization) Single system image Diversity and Dynamism Centralized Job Distributed Job management & scheduling Management & scheduling system Volunteer computing. Volunteer computing is an arrangement in which people (volunteers) provide computing resources to projects, which use the resources to do distributed computing and/or storage. ● Volunteers are typically members of the general public who own Internet-connected PCs. Organizations such as schools and businesses may also volunteer the use of their computers. ● Projects are typically academic (university-based) and do scientific research. But there are exceptions; for example, GIMPS and distributed.net (two major projects) are not academic www.bonic.com What is B.O.I.N.C ? is a massive open-source grid computing tool by the university of berkeley. How BOINC works ? How the software works CREDIT The project's server keeps track of how much work your computer has done; this is called credit. To ensure that credit is granted fairly, most BOINC projects work as follows: ● Each task may be sent to two computers. ● When a computer reports a result, it claims a certain amount of credit, based on how much CPU time was used. -
