EGEE: Enabling Grids for E-SciencE
The EGEE project brought together experts from more than 50 countries with the common aim of building on recent advances in Grid technology and developing a service Grid infrastructure which is available to scientists 24 hours-a-day.
The project provided researchers with access to a production level Grid infrastructure, independent of their geographic location. The project's main focus was:
- To expand and optimise Europe's largest production Grid infrastructure, namely EGEE, by continuous operation of the infrastructure, support for more user communities, and addition of further computational and data resources.
- To prepare the migration of the existing production European Grid from a project-based model to a sustainable federated infrastructure based on National Grid Initiatives for multi-disciplinary use.
This work was developed continually through three successive project phases: EGEE‐I, II and III. In Phase 1 EPCC led the development of two key pieces of network-level Grid software:
- Network Performance Monitoring (NPM), providing access to standardised network performance characteristics.
- Bandwidth Allocation and Reservation (BAR), allowing Grid middleware to make immediate and advance reservations of network connectivity specified in terms of bandwidth, duration and quality of service.
In Phase 2 EPCC was responsible for the brokering of network performance monitoring measurements collected across the EGEE Grid infrastructure. The results of the project included:
- A Grid infrastructure spanning about 250 sites across 50 countries.
- An infrastructure of more than 68,000 CPU available to users 24 hours a day, 7 days a week.
- More than 20 Petabytes (20 million Gigabytes) of storage.
- Sustained & regular workloads of 150K jobs/day, reaching up to 188K jobs/day.
- Massive data transfers > 1.5 GB/s.
- A single access point for support, a portal with well-structured information and updated documentation, knowledgeable experts, correct, complete and responsive support and tools to help resolve problems.
