JULEA: A Flexible Storage Framework for HPC

The group develops the JULEA storage framework, which can be used to easily prototype new ideas related to storage and file systems. It allows offering arbitrary I/O interfaces to applications and includes object, key-value and database backends with support for popular storage technologies such as POSIX, LevelDB and MongoDB. Additionally, JULEA allows dynamically adapting the I/O operations' semantics and can thus be adjusted to different use-cases. It runs completely in user space, which eases development and debugging.

It is open source and can be found on GitHub. JULEA is used in teaching and students have contributed several major new features. Moreover, it serves as the foundation of the CoSEMoS project to explore the benefits of a coupled storage system for self-describing data formats.
