TLDR
A probabilistic method is proposed for reading remote clocks in distributed systems subject to unbounded random communication delays and can achieve clock synchronization precisions superior to those attainable by previously published clock synchronization algorithms.Abstract:
A probabilistic method is proposed for reading remote clocks in distributed systems subject to unbounded random communication delays. The method can achieve clock synchronization precisions superior to those attainable by previously published clock synchronization algorithms. Its use is illustrated by presenting a time service which maintains externally (and hence, internally) synchronized clocks in the presence of process, communication and clock failures.read more

Clock Synchronization for Many-Core Processors
TL;DR: This work was the objective of reducing the effect of clock skew in many-core architectures, so that the Kalray MPPA-256 architecture can take full advantage of this hardware type in real-time applications.

TL;DR: The developed mechanism makes use of the built-in counters on sensors and external synchronization signals to align data streams to reduce the communication overhead and clock synchronization overhead on sensors nodes.

Optimized authenticated self-synchronizing Byzantine agreement protocols
TL;DR: This paper introduces so-called optimized authenticated self-synchronizing BAPs, that require fewer messages than the existing authenticatedSelf- Synchronized Byzantine agreement protocols, which require much communication overhead.

Uniform timing of a multi-cast service
TL;DR: The protocol implements the gradual tuning of the clocks, in order to automatically compensate the systematic drift and increase the time between re-synchronizations.

Synchronizing clocks in the presence of faults
TL;DR: Three algorithms for maintaining clock synchrony in a distributed multiprocess system where each process has its own clock work in the presence of arbitrary clock or process failures, including “two-faced clocks” that present different values to different processes.

Optimal clock synchronization

TL;DR: This is the first known solution that achieves optimal accuracy—the accuracy of synchronized clocks (with respect to real time) is as good as that specified for the underlying hardware clocks.

A new fault-tolerant algorithm for clock synchronization
Jennifer Lundelius,Nancy Lynch +1 more
TL;DR: A new fault-tolerant algorithm for solving a variant of Lamport's clock synchronization problem for a system of distributed processes that communicate by sending messages, which solves the problem of maintaining closely synchronized local times, assuming that processes' local times are closely synchronized initially.

A new fault-tolerant algorithm for clock synchronization
Jennifer L. Welch,Nancy Lynch +1 more
TL;DR: A new fault-tolerant algorithm for solving a variant of Lamport's clock synchronization problem for a system of distributed processes that communicate by sending messages that maintains synchronization to within a small constant, whose magnitude depends upon the rate of clock drift, the message delivery time and its uncertainty.
