In this project, the EU-US team plans to run thorough experimental evaluations on the performance of a novel protocol ARES [1], which implements an Atomic Distributed Shared Storage space over asynchronous, failure prone, message passing network nodes, and it ensures data availability and survivability. The EU-US team will design experiments that will test ARES performance under scalability, resource intensive, and fault-tolerance scenarios, and attempt to identify bottlenecks and shortcomings that may prevent ARES from being readily applied in a real, practical system. Cross-Atlantic experiments will be conducted by reserving network nodes both in the EU (through Fed4FIRE+ testbeds) as well as in the US through infrastructure at Penn State University (PSU) premises.
