The e-ROSA project seeks to build a shared vision of a future sustainable e-infrastructure for research and education in agriculture in order to promote Open Science in this field and as such contribute to addressing related societal challenges. In order to achieve this goal, e-ROSA’s first objective is to bring together the relevant scientific communities and stakeholders and engage them in the process of coelaboration of an ambitious, practical roadmap that provides the basis for the design and implementation of such an e-infrastructure in the years to come.
This website highlights the results of a bibliometric analysis conducted at a global scale in order to identify key scientists and associated research performing organisations (e.g. public research institutes, universities, Research & Development departments of private companies) that work in the field of agricultural data sources and services.

Design and use of the CPAN Branch & Bound for the solution of the Travelling Salesman Problem (TSP)
This article presents the design of a High Level Parallel Composition or CPAN (according to its Spanish acronym) that implements a parallelization of the algorithmic design technique named Branch & Bound and uses it to solve the Travelling Salesman Problem (TSP), within a methodological infrastructure made up of an environment of Parallel Objects, an approach to Structured Parallel Programming and the Object-Orientation paradigm. A CPAN is defined as the composition of a set of parallel objects of three types: one object manager, the stages and the Collector objects. By following this idea, the Branch & Bound design technique implemented as an algorithmic parallel pattern of communication among processes and based on the model of the CPAN is shown. Thus, in this work, the CPAN Branch & Bound is added as a new pattern to the library of classes already proposed in [9], which was initially constituted by the CPANs Farm, Pipe and TreeDV that represent, respectively, the patterns of communication Farm, Pipeline and Binary Tree, the latter one implementing the design technique known as Divide and Conquer. As the programming environment used to derive the proposed CPANs, we use C++ and the POSIX standard for thread programming.
