The technique

Brute-force search is implemented

Can run in massive distributed parallel

Tabulation of APDF

Use of Grid

To run you code on grid you should:

Make sure your app will actuallyrun on execution nodes

Have skills to use particular queue/resource manager

Understand grid security

Summary

Prototype of application that simplifies the use of grid

in geophysics

Brute force search method of inverse problem solution

Way to monitor running jobs

Avoiding security enabled us to provide simple way of running apps on grid

11

To do

Implement more inverse problem applications

Implement fast methods instead of brute force

Develop visualization tools

Security and flexibility
