Be Aware of Your Leaders
Shir Cohen, Rati Gelashvili, Lefteris Kokoris Kogias +4
Advances in blockchains have influenced the State-Machine-Replication (SMR) world and many state-of-the-art blockchain-SMR solutions are based on two pillars: Chaining and Leader-r…
Be Prepared When Network Goes Bad: An Asynchronous View-Change Protocol
Rati Gelashvili, Lefteris Kokoris-Kogias, Alexander Spiegelman +1
The popularity of permissioned blockchain systems demands BFT SMR protocols that are efficient under good network conditions (synchrony) and robust under bad network conditions (as…
Fast Graphical Population Protocols
Dan Alistarh, Rati Gelashvili, Joel Rybicki
Let be a graph on nodes. In the stochastic population protocol model, a collection of indistinguishable, resource-limited nodes collectively solve tasks via pairwise in…
L3 Fusion: Fast Transformed Convolutions on CPUs
Rati Gelashvili, Nir Shavit, Aleksandar Zlateski
Fast convolutions via transforms, either Winograd or FFT, had emerged as a preferred way of performing the computation of convolutional layers, as it greatly reduces the number of…
Why Extension-Based Proofs Fail
Dan Alistarh, James Aspnes, Faith Ellen +2
We introduce extension-based proofs, a class of impossibility proofs that includes valency arguments. They are modelled as an interaction between a prover and a protocol. Using pro…
Towards Reduced Instruction Sets for Synchronization
Rati Gelashvili, Idit Keidar, Alexander Spiegelman +1
Contrary to common belief, a recent work by Ellen, Gelashvili, Shavit, and Zhu has shown that computability does not require multicore architectures to support "strong" synchroniza…
