Development of Polish Infrastructure for Advanced Scientific Research - Status and Current Achievements

Big science needs synergistic approach from theory, experiment and computations. Significance of the computational science is still on its way up due to the importance of results concerning features of extreme time and space scales as well as of multiscale phenomena being a subject of current research. These needs have been recognized internationally and one of the activities undertaken in the last decade is the European Grid Infrastructure, consolidating national efforts on computational infrastructures developed under National Grid Initiatives (NGI). In the paper we present the way of building Polish NGI established for Polish scientists, allowing them to conduct interdisciplinary research on a national scale, and giving them transparent access to international grid resources via affiliated international grid infrastructures. The approach applied in setting up this e-infrastructure ensured integration with other similar platforms around the world, recently with special focus on domain specific solutions.
