iSGTW Technology - GridWay: interoperability without the headache

Technology - GridWay: interoperability without the headache The GridWay metascheduler can schedule jobs across several grids, including Open Science Grid, EGEE and TeraGrid.Image courtesy of GridWay What looks and feels like your Local Resource Management system, but lets you submit jobs to multiple heterogeneous grids? Sounds like the beginning of a bad joke or pipe dream? You might need to upgrade your metascheduler.So says Tino Vazquez Blanco, a grid technology engineer working on the GridWay metascheduler project.“GridWay allows you to do much more than your local LRM system. You can of course use GridWay to submit, monitor, and control your jobs; the added bonus is that you can do this across several different grids.”GridWay is a scheduler for other schedulers, Blanco explains. “It simulates a familiar environment, so it’s as if you’re working on a local cluster, but in fact you’re working across grids formed by heterogeneous clusters. You don’t need to worry about where the cl

iSGTW Feature - At home in Africa: African scientists plug into the global computer

Feature - @home in Africa: African scientists plug into the global computer During last week’s hands-on AFRICA@home workshop African scientists installed servers and set up a new volunteer computing project. This tangible experience allows them to harness the power of volunteer computers across the globe to support research into major issues affecting Africa.Image courtesy of AFRICA@home Volunteer computing projects like SETI@home, Einstein@home and LHC@home are providing scientists with huge computing resources, donated by the public. So, imagine what African scientists could do if they could tap into the power of the millions of idle computers around the world...Sounds crazy? In fact, this was the subject of a workshop held 16-22 July at the African Institute for Mathematical Sciences (AIMS) in Muizenberg, South Africa. The workshop’s 35 participants came from 18 African countries and were selected from scores of applications.Possibilities for AfricaCan African scientists really benefit from volunteer computi

SimCity, social engineering, and 60 million "people"

Feature - SimCity, social engineering and 60 million "people"

The ever-popular SimCity games allow players to create and manipulate their own fictional cities. Now grid computing is allowing researchers to do the same, this time with real social and geographic data. Image © Electronic Arts Inc. All rights reserved.

How long are you expected to live? Where do you go to hospital? Do you own your own home? How often do you go to football games?If you’re from the UK, chances are Mark Birkin has all of these answers…only he doesn’t know exactly which of his 60 million simulated “people” you are.A geographer by training, Birkin is part of a University of Leeds team using grid computing to run predictive models in their own real-life version of “SimCity”: integrating real Census data, survey data, healthcare data and more in an anonymous but accurate model of the entire UK population, and then projecting that information into the future.&ldqu
