Grid-projects

Grid-initiatives and projects worldwide

Globus Alliance – is the project on working out fundamental grid-technologies

Creation of Globus Toolkit which is one of the first variants of the “intermediate software” (middleware) for realization of the distributed grid infrastructure became one of the major achievements of the Globus project. Globus Toolkit became the standard de facto on realization of grid-systems. The given toolkit realizes mechanisms of services which cover security aspects, detection of the information, data control and resources, communications, detection of errors etc. Now this toolkit is used in many projects worldwide.

Projects of development of various variants of program environments (middleware) for the realization of grid-systems:

Legionhttp://legion.virginia.edu/index.html/

Condorhttp://www.cs.wisc.edu/condor/

Unicorehttp://www.unicore.eu/

ARC http://www.nordugrid.org/middleware/

gLitehttp://glite.cern.ch/

In 2010, four large consortia: gLite, ARC, UNICORE and dCache joined forces to develop and unify middleware in a common project called EMI (European Middleware Initiative, http://www. eu-emi.eu) .

EGEE and WLCG projects

EGEE (Enabling Grids for E-sciencE) and WLCG (Worldwide LHC Computing GRID) projects occupy a special place among grid-projects.

The EGEE project («Expansion of grid-systems for e-science development») has embodied a plan in the validity to transform world computer resources into a uniform homogeneous environment where they can be used in common on a world scale.

The project was financed by the European Community and the member-countries. As a result there was the highly productive world infrastructure much more surpassing by the possibilities of local clusters and the separate centers. The EGEE project has been successfully finished in April, 2010.

Over 140 organizations from more than 50 countries which have been united in 13 federations (one of which is «Russia»), and represented almost all main international and national European grid-projects, and also projects in the USA and Asia entered into EGEE consortium. Besides, set of related projects (more than 50 associated participants) have extended the grid-infrastructure to the Mediterranean, Baltic, Latin America, India and China.

EGEE Grid infrastructure has become an everyday working tool for a number of large and small research communities: high-energy physics, biological sciences and related disciplines, earth sciences, astrophysics, computational chemistry, fusion and other. The number of users of the EGEE infrastructure, united in more than 200 virtual organizations, was more than 14000 people, and every day on the EGEE infrastructure was carried out more than 400 thousand jobs, i.e. more than 12 million jobs per month.

WLCG (Worldwide LHC Computing GRID) was adopted in 2001 at CERN in order to create a global information infrastructure for processing, storage and analysis of data obtained during experiments conducted at the Large Hadron Collider.

To resolve that grand problem, the large-scale global Grid infrastructure, based on regional centers at various levels, providing simulation, storage and transferring of data from the Large Hadron Collider, has been constructed.

EGI infrastructure

Upon completion of the EGEE project, from April, 2010, the European Grid Infrastructure project began to operate (EGI – European Grid Infrastructure). The basis of this initiative is collaboration between the national grid infrastructures (National Grid Initiatives, NGIs) and coordinating agency (the EGI Organization, EGI.eu). This cooperation should be further development of sustainable and permanent global Grid infrastructure that ensures optimal use of computing resources and storage resources.
