The Need for Pervasive In Situ Analysis and Visualization (P-ISAV).

A major direction for big science is the coupling of HPC, experimental and observational facilities into computing ecosystems. These ecosystems will provide unprecedented tools for scientific inquiry. At the same time, these systems, which are complex, distributed and heterogeneous, will be a significant challenge for the visualization tools of today. In this position paper, we present our thoughts and key properties on a fundamental requirement of future solutions: pervasive in situ visualization (P-ISAV).
