The European Grid Infrastructure (EGI) is a publicly funded e-infrastructure put together to give European scientists access to more than 320,000 logical CPUs, 180 PB of disk space, 167 PB of tape space and data, which together drive research and innovation within their own research domains. More than 1.7 M compute jobs are processed every day in EGI!
EGI supports computing - including MPI, compute workload management services, data access and trasfer, data catalogues, storage resource management, and other core serivces such as user authentication, authorization and information discovery. EGI provides services that enable other activities to flourish. Roads pave the way to quicker and more efficient movement of people and goods – thus benefiting the economy and society. EGI allows researchers to share information securely, analyse data efficiently and collaborate with colleagues worldwide – thus driving research and innovation to the next level.
Resources are provided by about 350 resource centres who are distributed across 56 countries in Europe, the Asia-Pacific region, Canada and Latin America.
Infrastructures are the physical structures and facilities we need to operate a functional society – examples of public infrastructures include roads & motorways, the power-cable network or airports. Likewise, an e-infrastructure provides the electronic infrastructure needed to support different activities – examples of public e-Infrastructure include networks, storage, data, computers or other resources that are integrated to serve a particular need. EGI is a collection of computers grouped together in resource centres, in turn connected to each other through high-performance network links. The overall picture is a geographically distributed network of computer clusters which can be accessed by all authorised users.
