2 SEEGRID PSC 03 Meeting – Podgorica, Monte Negro, 30.10.-2.11.20062 SEE-GRID-1 project Objectives  Establish at least 1 fully operational grid site in all participating SEE countries  Each contractor to set up at least one site; third-parties to set up additional sites  Deploy at least 2 Grid applications developed by EGEE (one from the HEP, one from Biomed) in the regional infrastructure and demonstrate their usage over the regional infrastructure  Deploy at least two Grid applications developed by SEE-GRID partners in the regional infrastructure.  Create a Human Network in eInfrastructures and raise awareness in the wide R&E community per country

3 SEEGRID PSC 03 Meeting – Podgorica, Monte Negro, 30.10.-2.11.20063 SEE-GRID-1 Applications Regionals applications  VIVE – Volumetric Image Visualisation Environment  SE4SEE – Search Engine For SEE

4 SEEGRID PSC 03 Meeting – Podgorica, Monte Negro, 30.10.-2.11.20064 VIVE - Introduction Objective Complete interactive analysis of 3D datasets from medical imaging devices (CT, MR, PET, SPECT…) Easy remote access over the Internet Generalized 3D tools for diagnosis, surgical planning, and therapy evaluation Virtual distant examination based on 3D datasets Basic idea Split the system into a client and server part Dedicate the server part to access and processing of volumetric data Produce a lightweight client for user interaction and 3D rendering Exploit grid resources and paradigms to overcome implementation issues

5 SEEGRID PSC 03 Meeting – Podgorica, Monte Negro, 30.10.-2.11.20065

6 SEEGRID PSC 03 Meeting – Podgorica, Monte Negro, 30.10.-2.11.20066 Screnshots - From Atoms to Galaxies

7 SEEGRID PSC 03 Meeting – Podgorica, Monte Negro, 30.10.-2.11.20067 What Can We Gain From the Grid? Distribution of processing and data over several nodes  Grid submission used to allocate server jobs  Allocating several machines for texture and surface mesh creation  Field stripping is not necessary for the regular medical images  Grid reduces overall demand for CPUs even with one server job per session  Could build distributed virtual data centers, with data abstracted within electronic health record Data transfer and replication  Replication of data to locations close to computation elements  Remote file access Security – high sensitivity of medical data  Data encryption in transfer (GridFTP, dCache, RFIO and gsidcap)  Anonymisation - removal of personal details to prevent intrusion at machine level, solved by gLite Hydra Application-specific monitoring  Could select a site from performance indicators (responsiveness, bandwidth, round trip time, processing speed) provided by the grid  Currently we just collect and display monitoring data using in our implementation guidelines and ideas from various grid/network monitoring projects  Fault tolerance

8 SEEGRID PSC 03 Meeting – Podgorica, Monte Negro, 30.10.-2.11.20068 SE4SEE - Introduction Grid-enabled crawling of all Web pages in SEE countries Grid-enabled categorization of these Web pages A navigational search facility over the classified content To sum up, we offer : A grid-enabled, directory-based search engine that will enhance the cultural integration in the region

9 SEEGRID PSC 03 Meeting – Podgorica, Monte Negro, 30.10.-2.11.20069 SE4SEE - Grid-Enabled Web Crawling The size of the Web is enormous; Web crawling requires:  high download rates over the network  excessive storage (both memory and disk)  vast amount of processing power It is hard to crawl the Web by a centralized system Solution: Grid-enabled Web crawling since  geographically distributed grid nodes allow fast download rates and dispersion of the network load  excessive disk and memory capacities together with the huge CPU power of GRID provides the necessary medium for storing and processing the vast Web content
