University Computing centre SRCE is organizing annual event „e-infrastructure Day 2014“ that will be held this year on December 3rd 2014 in SRCE, Josipa Marohnica 5, Zagreb. This event traditionally brings together users, developers and operators of e-infrastructure, as well as representatives of academic institutions, financiers and business representatives. A series of lectures and presentations in the field of e-infrastructure serve as an opportunity to exchange knowledge, experience, and reflect on the further development and use of resources across all layers of the e-infrastructure. This year's program (CRO) is dedicated to the presentation of new resources and services of the e-infrastructure and giving a review of the existing infrastructure. With a series of interesting presentations, users will share their first-hand experience in the use of e-Infrastructures in their research work.
