EC-GIN - Analysis of Grid Applications
by Yehia El khatib 21 May '07

21 May '07

Hello all. I am a research assistant at the Computing Department in Lancaster University, UK. I am working on the EC-GIN project, which was introduced by Sven Hessler during the GHPN session at OGF20. Europe-China Grid InterNetworking (EC-GIN) is an EU-funded project* concerned with improving the network ability to support Grid applications and services. One of the first tasks as part of the project is to study Grid applications that have been used or are currently being used in the field of e-science as well as other fields. We wish to come up with an analysis of the network demands and behavior of these applications. For this purpose, we have put together a short questionnaire (14 questions). It is aimed at collecting information about the network requirements of grid applications as perceived by application designers, developers, and administrators. As Sven mentioned in his presentation, we are seeking your cooperation by answering the questionnaire, which can be done in one of the two following ways: 1. The survey can be answered online at: http://freeonlinesurveys.com/rendersurvey.asp?sid=vlz28x01dk8elfc300530 2. The survey is also available in .doc and .pdf formats at the following location: ftp://148.88.225.74/opendir/ Please email the filled forms to me (yehia at comp.lancs.ac.uk). We are interested in your feedback and highly appreciate it. * EC-GIN is a Framework 6 STREP project. Action Line: IST-2005-2.6.5.1.c Grids China Project Reference: 045256 http://www.ec-gin.eu Best regards, Yehia El khatib Research Assistant Computing Department Lancaster University yehia(a)comp.lancs.ac.uk +44 (0)787 057 0318

Chicken Chicken Chicken
by Chris Kantarjiev 11 May '07

11 May '07

Here are the relavent links: http://www.youtube.com/watch?v=yL_-1d9OSdk The paper is available at http://isotropic.org/papers/chicken.pdf The presentation is available at http://isotropic.org/papers/chicken.ppt I suspect the author was inspired by http://www.scs.cs.nyu.edu/~dm/remove.pdf which was (successfully!) submitted to a conference whose organizers relentlessly spam researchers with the call-for-papers, ignoring all requests to unsubscribe from their mailing list. Do check out the figures, and also http://pdos.csail.mit.edu/scigen/ which likewise lead to a successful publication. (If you don't know what this is about, you should have come to the F2F!) Best, chris

OGSA F2F meeting on Friday at UoM
by Hiro Kishimoto 10 May '07

10 May '07

Hi all, OGSA-WG F2F meeting will start 9am on Friday. Since it is about 10 minutes walk from MICC, we will meet at the meeting room (Mercury room 1.19) at 9am #. See you all tomorrow. https://forge.gridforum.org/sf/go/wiki1714 > * Date: 11 May, 2007 > * Time: 9am - 5pm > * Location: The University of Manchester > > * Building: Kilburn, School of Computer Science, which is > building 39 (near centre of campus map); there's a bus stop directly > outside the building. Buses along Oxford Road are very frequent (bus > network map) and best caught from outside the Palace Hotel if you're > staying near the OGF venue, though that's only about 10 minutes away > from our building by foot. The entrance is not at street level but > rather two stories up (the upper entrance in this fairly recent > picture, just under the notice saying "Kilburn Building"); you will > need to use either the paved stairway outside building 32 (turn > right by 180 degrees at the top) or the metal stairs at the > south-western corner of the Kilburn building. > > * Room: Mercury (1.19) - we may change this to one of the > neighbouring rooms; check for posted signs once you enter the > department. There are also internal floor maps posted. All of these > rooms are on the level that you enter at. All may be reached by > following the corridor round the edge of the roof garden with the > sculpture in it. -- Hiro Kishimoto

Glossary terms for Thursday's call
by Treadwell, Jem 01 May '07

01 May '07

HI, I've uploaded version 4 of the glossary - this version includes the changes for deployment and provisioning, as agreed at the last discussion. You'll find it at http://tinyurl.com/2mo6r3. For Thursday's call I propose to discuss the following terms, as time permits o State. We had discussed this, and Jay has an action to improve the current proposal. So far I haven't had a proposal from Jay, but we need to put this one to bed, so we'll have a brief discussion and if we don't have a better proposal at the meeting I'll go with what we have. There will be an opportunity to improve this or any term in the final review. o Resource, Grid component, and Service. We had definitions for Resource and Service in both the OGSA and the EGA glossaries, so we need to produce a consolidated definition. Grid component comes from the EGA glossary. I've condensed it from the original, but (hopefully) haven't changed its meaning. Rather than reproduce these terms here please take a look at the working/discussion document, which you'll find at http://tinyurl.com/23a6zd. These are the first four terms listed, and the text you'll find is a starting point for discussion. If you have comments and you're not going to make tomorrow's meeting, please pass them on to me; otherwise I'll follow up after the meeting with revised text for review. Thanks! - Jem Jem Treadwell Software Engineer HP Software 856.638.6021 office | 856.638.6190 fax | jem.treadwell(a)hp.com 6000 Irwin Road | Mount Laurel | NJ 08054 www.hp.com/go/software <http://www.hp.com/go/software>
