10. Storage status

11. RoSpaceGRID - PECS-ESA Romanian GRID middelware repository for Space Science Applications The RoSpaceGRID framework is an implementation of GRID which consists of clusters, labs with distributed computing resources all around the world, where computer activities can be submitted for scheduled execution. The RoSpaceGRID is deployed in Institute of Space Science (ISS) for PLANCK, CLUSTER II and VENUS EXPRESS space missions. This project will be established for the benefit and in cooperation with the scientific community of the three missions mentioned above. R&D GRID

12. Future developments Main data traffic : WNs local storage Change local network infrastructure to 10 GigE (dec 2011 – jan 2012)

13. CUDA parallel computing Compute Unified Device Architecture ­ NVIDIA General purpose parallel computing for GPU Requirements: ISA(Instruction Set Architecture) NV driver CUDA Toolkit (CUDA SDK)
