Goals of the “Grid Enabled SEE++”

• it speeds up the Hess-Lancaster test simulation (parallel gaze

pattern calculation);

• it determines/estimates the pathology of the patients in reasonable

time (grid based pathology fitting);

• It collects, stores, shorts and evaluates patient data and known

pathological cases for improving the future medical treatments (grid enabled medical database). The goal of project is to develop an efficient grid- based tool for ``Evidence Based Medicine'', which supports the surgeons in the following ways:

Former Results

Initial Grid Enabled Architecture We speeded up the Hess-Lancaster test by a factor of 14-17 Karoly Bosa, Wolfgang Schreiner, Michael Buchberger, Thomas Kaltofen, SEE-GRID, A Grid-Based Medical Decision Support System for Eye Muscle Surgery, 1st Austrian Grid Symposium, December 1-2, 2005, Hagenberg,

We designed a grid-enabled Pathology Fitting algorithm We developed a Web Service based medical database for SEE++

Security for the SEE++ Databases

I.) Security between the SEE++ clients and the bridge (outside of the grid) : II.) Security between bridge and the WSRF Databases (inside of the grid) : Encrypting any network transfer via HTTPS or SSL by Stunnel. a.) Solutions developed for system b.) Solutions provided by Globus 4 Encrypting any network transfer (planned). Checking the authorization of the bridge by certificates (planned). For each Web Service call, the caller's identity is checked separately (User ID + Password). Stored user passwords is encrypted with an SHA-512 salted hash.

A Comparison of the two Designs

For the Computational Tasks: Globus 4 gLite 3.0.0 For the Grid-enabled Databases: Globus 4 gLite 3.0.0

In both cases we intend to use some kind of server jobs (as executers) started via Workload Management System (WMS) of gLite and WS-GRAM of Globus. To return the port number of the server to client, we will use interactive jobs. To return the port number of the server to client, we use our own solution. We plan to use AMGA to provide : certificate based user authentication unified user interface for the databases residing on the grid. We apply our own developments to provide : password based user authentication unified user interface for the databases residing on the grid.

Outlook

We intend to report the outcome of a comparative benchmarks : between the usage of the pre-WS and the WS-GRAM APIs, between the earlier applied prototype (Web Service based) implementation and the WSRF-based implementation of the SEE++ databases and between a gLite variant and the other “Grid Enabled SEE++” version based on the Globus Toolkit 4.
