EGI

International scientific communities can draw many benefits from a strong partnership with EGI. EGI offers grid-ready applications, training resources, workshops and forums, help and support, as well as involvement in an open development process. In turn, VRCs provide EGI with their technical and service requirements, which are then fed into the overall development of the infrastructure as a true user-driven resource.

  • EGI Home Page
    The European Grid Infrastructure enables access to computing resources for European researchers from all fields of science, from High Energy Physics to Humanities.
  • EGI Central Operations Portal
  • User Community Support in EGI
    Whether you are an individual researcher, a small research group or an international community this page will offer directions to resources and services that you might need. The User Community Support page of the EGI web site allows to access information on the following topics:
    • VRC Gateways: They allow to connect with the European Grid Infrastructure and other related Distributed Computing Infrastructures.
    • NGI Support Teams: Each individual National Grid Initiative (NGIs) has a team dedicated to User and Community Support that can help existing and prospective users to connect with e-Infrastructure resources.
    • EGI support services.
    • Applications Database: The EGI Applications Database (AppDB) stores information about grid-based computing tools for scientists to use.
    • Services and Tools: The EGI VO Services team supports the processes of starting-up, managing, operating and monitoring VOs, pointing out to tools, services, documentation and procedural guidelines to maximize the usage of resources.
    • Training marketplace: The EGI Training Marketplace exists as a service to coordinate training across communities, projects and national teams.
    • EGI Helpdesk system (GGUS): the most suitable option for problems experienced with the production infrastructure.

The Requirements Gathering Process in EGI

The Requirements Gathering Process is currently one of the most important hot topics in EGI. The evolution of the European Grid Infrastructure is driven by the users. Therefore capturing and communicating feedback from users to the infrastructure as well as technology operators and providers is a key goal for NA3 and for the project as a whole. This EGI web page describes the channels, processes and bodies that the User Community Coordination activity established and runs in order to collect, capture, process, and report requirements and recommendations of users. Input from users are collected by NA3 through various electronic channels and face-to-face communication mechanisms.
The Requirements Tracking System (RT) is used to capture, analyse and prioritise requirements coming from the EGI communities. RT allows users, NGIs, technology providers and other partners to interact with the system to speed up the delivery of solutions.

Contributions from the A&A community to the requirements gathering process are of utmost importance. This ensures that features and functionalities requested by A&A applications to properly work when ported to Grid infrastructure are taken into account and met by the future releases of the EGI middleware and by its related tools and services. The A&A community therefore should participate more proactively to this process.

Areas in which A&A contributions could be brought (in terms of requirements, use-cases and test-beds) are:

  • Interactions between DCIs based on different technologies (Grid, HPC and Cloud)
  • Grid support to MPI
  • Accessing and controlling databases from Grid
