Portal Access

If users need access the the EGEE Grid's resources, they will have to be authorised through a Virtual Organisation (VO).

Once a member of a VO has been authorised, they will probably access the grid via a 'portal' (in this case we are using the GILDA Grid Tutor portal). A Portal is simply a webpage which leaves the complicated technicalities to the technicians, and allows the user to submit jobs in a relatively user friendly manner. Of course, you still need to know what you are doing, and the Grid tutorial explains the steps involved in preparing, submitting and retrieving a job on the grid. It is possible to use the grid without a portal just by using command line interfaces, but this demands a greater level of technical ability and will not be covered in this section.

Already a VO member?

If you have already gone through the process of being authorised as a user and you would just like to recap on using the portal, writing JDL files and submitting and recieving jobs, you should use this Grid tutorial.
