SwiftComp

The goal of the SwiftComp project is to propose efficient techniques to process large ammount of data.
To this end, we intend to leverage the properties of Conflict free Replicated Data Types, allowing computations to proceed in a decentralized way.

SwiftCloud is the twin project focusing on developing an efficent storage system for cloud environments.
