Logical Synchrony and the bittide Mechanism

S Lall, C Cas, M Izzard, T Spalink - IEEE Transactions on …, 2024 - ieeexplore.ieee.org
We introduce logical synchrony, a framework that allows distributed computing to be
coordinated as tightly as in synchronous systems without the distribution of a global clock or …

Logical Synchrony Networks: A formal model for deterministic distribution

L Kenwright, P Roop, N Allen, S Lall, C Caşcaval… - IEEE …, 2024 - ieeexplore.ieee.org
In the modelling of distributed systems, most Models of Computation (MoCs) rely on blocking
communication to preserve determinism. A prominent example is Kahn Process Networks …

On buffer centering for bittide synchronization

S Lall, C Caşcaval, M Izzard… - 2023 9th International …, 2023 - ieeexplore.ieee.org
We discuss distributed reframing control of bittide systems. In a bittide system, multiple
processors synchronize by monitoring communication over the network. Processors remain …

Modeling and Control of bittide Synchronization

S Lall, C Caşcaval, M Izzard… - 2022 American Control …, 2022 - ieeexplore.ieee.org
Distributed system applications rely on a fine-grain common sense of time. Existing systems
maintain this by keeping each independent machine as close as possible to wall-clock time …

Modeling Buffer Occupancy in bittide Systems

S Lall, T Spalink - arXiv preprint arXiv:2410.05432, 2024 - arxiv.org
The bittide mechanism enables logically synchronous computation across distributed
systems by leveraging the continuous frame transmission inherent to wired networks such …
