Astrophysics on the Grid
• MHD portal with Zeus3D
• Brett Beeson
• Collaborators– David Barnes (AusVO)– Andrew Melatos (MHD)– Slavisa Garic (NimrodG)– Astrogrid (MySpace)
![Page 2: Astrophysics on the Grid MHD portal with Zeus3D Brett Beeson Collaborators –David Barnes (AusVO) –Andrew Melatos (MHD) –Slavisa Garic (NimrodG) –Astrogrid](https://reader035.vdocuments.pub/reader035/viewer/2022062404/5514f45c550346a80c8b4e7f/html5/thumbnails/2.jpg)
Background
• Theory with the VO?
• Not just synthetic telescopes
• Publishing codes via the Web

Zeus Overview
• The Good– F77 (language of the Gods)– Free for academic use– Widely used, flexible
• The Bad– F77 (language of the Gods)– Complex to build (CPP,G77,libraries)– Difficult to use, easy to break

Portal Overview
• Why?– Make Zeus3D available to researchers
• Advantages over existing methods• Use Grid to distribute computation• Visualise results quickly
– Demonstrate theory on the VO – Explore integration of existing components.
• Globus, MySpace, Tomcat, NimRod
– Local demand at Melbourne University

Job Monitoring
• Mid-process monitoring
• Dead jobs restarted
• Monitor across clusters
• NimrodG provides for parameter sweep
