GLIF Secretariat and GLIF Sponsors:

The GLIF secretariat is provided by TERENA. Staff members of TERENA maintain the GLIF

website, organize the GLIF meetings and provide secretariat and management support to the

GLIF Working Groups. The costs of the secretariat are covered by the voluntary sponsorship of a

number of GLIF participants. In recent years, the following organizations have contributed to the

funding of the GLIF secretariat:

GLIF Events:

The GLIF infrastructure enables advanced applications, such as those demonstrated at the iGrid

2005 Workshop in San Diego, September 200522. IGrid events showcase advances in scientific

collaboration and discovery, by providing a forum for the world's premier discipline scientists,

computer scientists and network engineers to meet and work together in multidisciplinary teams

to understand, develop and demonstrate innovative solutions in a LambdaGrid world.

In addition to Working Group meetings, GLIF organizes one large event per year, known as the

annual LambdaGrid Workshop. The 7th Annual LambdaGrid Workshop was held on 17-18

September 2007 in Prague, Czech Republic. More than 100 people from research and education

networking organizations, universities, research institutes and industry participated. The

workshop was held in the Carolinum, the building that has housed the rectorate of Charles

University of Prague for more than 600 years. It was definitely not built with optical cabling in

mind. Arranging for lambda connectivity and other necessary facilities for GLIF demonstrations

therefore took an enormous effort from CESNET, but this hard work proved very worthwhile.

The Research and Applications Working Group had a particularly overloaded program, testifying

to the growth of lambda applications in various fields of research over the past year. This was

also reflected in the very advanced applications that were demonstrated at the workshop venue.

Particularly spectacular was a demonstration by the CineGrid organization of 4K high resolution

digital video transfer from Japan, The Netherlands and the USA. An experiment in remote

interactive digital film processing also had its world premiere, with partners in Prague, the USA

and Canada all working together to improve the color quality of a specially recorded film. The

quality of 4K digital cinema was staggering: larger and sharper than reality, four times better than

high-definition TV and ten times better than normal television. Further demonstrations of

CineGrid applications took place at the Barrandov film studios just outside Prague, and other

applications were demonstrated at the venue after the workshop concluded.

The Technical Issues Working Group issues addressed a diverse range of topics. Operators of

GLIF Open Lightpath Exchanges (GOLEs) announced the newest updates on equipment and

lambda deployments. This information exchange was complemented by discussions about the
