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