Proactive Data Containers

Proactive Data Containers (PDC) project

Novel data abstraction for managing science data in an object-oriented manner

R&D effort:

Formulation of object-oriented PDCs and their mapping in different levels of the exascale storage hierarchy;
Efficient strategies for moving data in deep storage hierarchies using PDCs
Techniques for transforming and reorganizing data based on application requirements
Novel analysis paradigms for enabling data transformations and user-defined analysis on data in PDCs

Low-contention Data Movement in Hierarchical Storage System

Scalable Object-centric Metadata Management
