WCGA has the objective to act as a forum for technical presentations of ongoing research and relevant activities in the area of Computational Grids, Infrastructure, Middleware Development and Applications, geting together researchers and professionals actively working in this area. The workshop also intends to form multi-instituional colaborative networks, groups with technical and scientific competence, and the strenghtning of ongoing actvities.

Previous editions of WCGA - 2005, 2004 & 2003 - have been held at LNCC (Petropolis - RJ), as part of the Summer Program, and generated substantial interest in the community and it is expected that this interest will continue. Far from exhausting the topics of interest, they have paved the way for a third edition of the workshop in the series. For WCGA 2006 workshop, researchers from the various GRID and Applications communities are encouraged to submit and present original work to be considered for publication.

The IV Workshop on Computational Grids and Applications (WCGA 2006) will be held on June 2nd - 2006, in conjunction with the Brazilian Symposium on Computer Networks (SBRC 2006), in Curitiba, Paraná, Brasil. It is as joint organization of LNCC, RNP, NCSA and SBRC 2006.
