Verification of Eventual Consensus in Synod Using a Failure-Aware Actor Model

Saswata Paul, Gul A. Agha, Stacy Patterson +1

Successfully attaining consensus in the absence of a centralized coordinator is a fundamental problem in distributed multi-agent systems. We analyze progress in the Synod consensus…

An Algorithm for Reconstructing the Orphan Stream Progenitor with MilkyWay@home Volunteer Computing

Siddhartha Shelton, Heidi Jo Newberg, Jake Weiss +16

We have developed a method for estimating the properties of the progenitor dwarf galaxy from the tidal stream of stars that were ripped from it as it fell into the Milky Way. In pa…

Skedulix: Hybrid Cloud Scheduling for Cost-Efficient Execution of Serverless Applications

Anirban Das, Andrew Leaf, Carlos A. Varela +1

We present a framework for scheduling multifunction serverless applications over a hybrid public-private cloud. A set of serverless jobs is input as a batch, and the objective is t…

Maximum Likelihood Fitting of Tidal Streams With Application to the Sagittarius Dwarf Tidal Tails

Nathan Cole, Heidi Jo Newberg, Malik Magdon-Ismail +10

We present a maximum likelihood method for determining the spatial properties of tidal debris and of the Galactic spheroid. With this method we characterize Sagittarius debris usin…
