Start Start 1 Million CPU hours provided for volunteer Desktop Grids from HPC centers Leslie Versweyveld http://degisco.eu/start/-/blogs/1-million-cpu-hours-provided-for-volunteer-desktop-grids-from-hpc-centers-1 2012-09-30T08:19:43Z 2012-07-10T13:09:09Z <p> In June 2012, the HPC centers of Desktop Grid Virtual Organisation (managed by the DEGISCO project) provided more than 1 Million normalized CPU hours for the supported volunter Desktop Grids in the last month.<br /> <br /> It was the first time when the e-Infrastructure reached this outstanding 1 Million CPU-hour level per month by utilizing the spare capacities of HPC clusters running gLite grid middleware. The new fault-tolerant, high-throughput, and geographically distributed 3G Bridge deployment (in Budapest by MTA SZTAKI, in Moscow by ISA-RAS, and in Taipei by ASGC) allowed us to gather 272,883 workunits from 10 different volunteer projects involving (among others) <a href="http://casathome.ihep.ac.cn/">CAS@home</a>, <a href="http://www.ibercivis.es/">Ibercivis</a>, <a href="http://dg.imp.kiev.ua/slinca/">Slinca@home</a>, <a href="http://sat.isa.ru/pdsat/">SAT@home</a> and <a href="http://szdg.lpds.sztaki.hu/szdg/">SZTAKI</a> Desktop Grid. The workunits have been bridged to the Desktop Grid VO resources, and after their execution the results have been successfully transferred back to their sources; to the scientific users communities.<br /> <br /> We would like to thank all the supporters from Grid centers for their help and assistance; especially from <a href="https://biruni.upm.my/">UPM/Biruni Grid</a> (Malaysia), <a href="http://www.gridcomputing.pt/">INGRID</a> (Portugal), <a href="http://www.grif.fr/">GRIF</a> (France), <a href="http://www.ipb.ac.rs/">IPB</a> (Serbia), and <a href="http://www.lpds.sztaki.hu/">SZTAKI </a>(Hungary).</p> <p> <img alt="" src="http://degisco.eu/image/image_gallery?uuid=a3070b1b-1489-43fd-9b31-29a17a295219&amp;groupId=10508&amp;t=1341925747642" style="width: 250px; height: 96px;" /></p> Leslie Versweyveld 2012-07-10T13:09:09Z XtremWeb-HEP 8.1.2 released Leslie Versweyveld http://degisco.eu/start/-/blogs/xtremweb-hep-8-1-2-released 2012-06-26T12:22:15Z 2012-06-26T12:17:45Z <div class="entry-body"> <p> DEGISCO project partner CNRS from the Laboratoire de l'Accélérateur Linéaire in Orsay, France has released the XtremWeb-HEP 8.1.2 version.</p> <p> Major points in this version include:</p> <ul> <li> Correction: inter node communication thanks to Jason Maassen from the Netherlands eScience Center in Amsterdam</li> <li> Correction: REST interface</li> <li> New feature: the server embeds Web service available through HTTPS</li> </ul> <p> A. Corrections:</p> <ul> <li> A.1 on server side, the scheduling improved: hosts.incomingconnection is now taken into account to ensure a server like job is not sent to a volunteer resource where incoming connections are not allowed</li> <li> A.2 on server side, the scheduling improved: restoring a feature from XtremWeb 1.8.0 by INRIA: "expected host" so that the end user can specify at submission time the expected volunteer resource to run the job.

The focus is on applications of citizen-based volunteer computing and volunteer sensing to earthquake science in South-East Asia. The purpose of the hackfest is to explore new concepts in distributed software and hardware, and brainstorm about how to increase web-based public participation in earthquake science.<br /> <br /> The two-day workshop tackles two specific challenges:<br /> The first day focuses on how to deploy the volunteer-based earthquake sensing project Quake Catcher Network in Taiwan and neighbouring regions of South-East Asia, such as Philippines, Indonesia and Vietnam. QCN provides seismic researchers with new and unique sources of information about seismic events. It is also contributing to public awareness about earthquake science.<br /> <br /> The second day focuses on integrating large-scale simulation packages for earthquake science with the volunteer computing platform BOINC, so that home PCs and laptops, as well as desktop grids in research institutes, may contribute to simulation-based research. Topics include volunteer cloud computing, bridging volunteer and grid resources, and services provided by the International Desktop Grdi Federation (IDGF).<br /> <br /> Guest speakers include Prof. Jesse Lawrence, Stanford School of Earth Sciences, Stanford University.<br /> <br /> Asia@home welcomes seismic scientists, grid and volunteer computing enthusiasts, and science education experts.</p> <p> More information is available at <a href="http://event.twgrid.org/isgc2012/asiaathome.html">http://event.twgrid.org/isgc2012/asiaathome.html</a></p> </div> Leslie Versweyveld 2012-01-03T08:40:15Z ISGC 2012 registration opens now Leslie Versweyveld http://degisco.eu/start/-/blogs/isgc-2012-registration-opens-now 2012-01-03T08:38:51Z 2012-01-03T08:38:40Z <div class="entry-body" id="aui-3-2-0PR1-12374"> <p id="aui-3-2-0PR1-12372"> The International Symposium on Grids and Clouds (ISGC) 2012 will be held at Academia Sinica in Taipei, from 26 February to 2 March 2012, with co-located events and workshops.

To enjoy the early bird discount rate, you can register before 13 January, 2012.</p> <p> "Convergence, Collaboration, Innovation" is the theme of ISGC 2012. The last decade has seen the wide-scale emergence of e-Infrastructure as a critical asset for the modern e-Scientist. The emergence of large-scale research infrastructures and instruments that has produced a torrent of electronic data is forcing a generational change in the scientific process and the mechanisms used to analyse the resulting data deluge.</p> <p> No longer can the processing of these vast amounts of data and production of relevant scientific results be undertaken by a single scientist. Virtual Research Communities that span organisations around the world, through an integrated digital infrastructure that connects the trust and administrative domains of multiple resource providers, have become critical in supporting these analyses.</p> <p> ISGC 2012 will be the 10th meeting, that over the last decade has tracked the convergence, collaboration and innovation of individual researchers across the Asia Pacific region to a coherent community and as a result has helped drive the growth of regional e-Science activities and its collaborations around the world.</p> <p> For more symposium information and detailed topic description, you can visit the conference website at <a href="http://event.twgrid.org/isgc2012/index.html">http://event.twgrid.org/isgc2012/index.html</a></p> <p> Topics of Interest include:<br /> <br /> <strong>Applications and results from the Virtual Research Communities and Industry:</strong><br /> 1.

The major ones are the ones, that resolved deadlock issues in the Commune components, and the ones related to Worker reallocation when other components fail. The team has also released Commune 1.0, which is a much lighter and faster version of Commune. This version uses JSON in the message structure, which resulted in smaller messages and faster serialization times.
