  44. 44. Summary and Conclusions (1/2) <ul><li>GILDA is a &quot;de facto&quot; standard t-Infrastructure adopted by several EU-FP6 and FP7 projects; </li></ul><ul><li>It is a complete suite of grid elements ( test-bed, CA, VO, monitoring system, web portal, user interfaces, support system ) and applications fully dedicated to dissemination purposes and pre-porting of new applications to EGEE-like Infrastructures; </li></ul><ul><li>It is also a digital inclusion tool by helping to spread Grid Computing knowledge around the world. </li></ul>
  45. 45. Summary and Conclusions (2/2) <ul><li>GILDA and Africa </li></ul><ul><ul><li>African scientific communities can use GILDA to “gridify” and run applications of local interest; </li></ul></ul><ul><ul><li>Institutions can setup “clones” of GILDA locally to implement campus grids or even nation-wide e-infrastructures (we are already doing so in South Africa and Cuba); </li></ul></ul><ul><ul><li>GILDA can offer free technical support for anyone willing to organize local training events on Grid computing </li></ul></ul><ul><ul><ul><li>It can be undergraduate courses, M.Sc courses, tutorials, Grid Schools etc. </li></ul></ul></ul>
