Data Analysis of Ensemble Simulations: an In Situ Approach using Damaris
As we approach exascale, simulations running on ever more cores on supercomputers produce ever larger data that has to be stored for subsequent analysis. With unmatched storage and computation performance, in situ analysis has been proposed as a way to run analysis tasks along with the running simulation. While this reduces the need to store massive amounts of raw data and lets scientists get a direct insight into their simulation, it does not allow to compare multiple runs of the same simulation (ensemble simulations), as these runs are not performed at the same moment. Thus in situ approaches remain limited and ensemble simulations still requires to store raw data. We present a complete framework for comparing data produced by different runs of the same simulation. This framework uses the Damaris I/O middleware to re-load data from previous experiments inside a running instance of the simulation, allowing a direct in situ comparison of data between older and current runs.

Active Data: A Programming Model to Manage Data Life Cycle Across Heterogeneous Systems and Infrastructures
The Big Data challenge consists in managing, storing, analyzing and visualizing these huge and ever growing data sets to extract sense and knowledge. As the volume of data grows exponentially, the management of these data becomes more complex in proportion. A key point is to handle the complexity of the data life cycle, i.e. the various operations performed on data: transfer, archiving,
replication, deletion, etc. To alleviate the complexity of the data life cycle, we propose Active Data, a programming model to automate and improve the expressiveness of data management applications. We first introduce the concept of data life cycle and define a formal model that allow to expose data life cycle across heterogeneous systems and infrastructures. The Active Data
programming model allows code execution at each stage of the data life cycle: routines provided by programmers are executed when a set of events (creation, replication, transfer, deletion) happen to any data. We implement and evaluate the model with four use cases: a storage cache to Amazon-S3, a cooperative sensor network, an incremental implementation of the MapReduce
programming model and automated data provenance tracking across heterogeneous systems. Altogether, these scenarios illustrate the adequateness of the model to program applications that manage
distributed and dynamic data sets. We also show that applications that do not leverage on data life cycle can benefit from Active Data to improve their performances.
