Composable Reliability for Asynchronous Systems
Distributed systems often employ replication to solve two different kinds of availability problems. First, to prevent the loss of data through the permanent destruction or disconnection of a distributed node, and second, to allow prompt retrieval of data when some distributed nodes respond slowly. For simplicity, many systems further handle crash-restart failures and timeouts by treating them a...
متن کاملOther Agents' Actions as Asynchronous Events
An individual planning agent does not generally have sufficient computational resources at its disposal to produce an optimal plan in a complex domain, as deliberation itself requires and consumes scarce resources. This problem is further exacerbated in a distributed planning context in which multiple, heterogeneous agents must expend a portion of their resource allotment on communication, nego...
متن کاملFDAE: A failure detector for asynchronous events
Detecting element failures is a relevant issue in distributed systems. A fault tolerant system needs to detect a failure and recover from it promptly. In fact, traditional approaches to fault tolerance are usually not completely free from errors during the failure detection phase; a good failure detector is thus a very important component of them to minimize these errors. In this paper we prese...
متن کاملPān̄ini: A Language with Asynchronous, Typed Events
Writing programs using explicit concurrency constructs such as threads is hard and error prone. To solve this problem many recent language design efforts have focused on features that manage the details of concurrency behind the scene, while exposing easy to use and checked programming discipline to the programmers. The subject of this work, the Pān̄ini language, has similar goals. To that end, ...
متن کاملAsynchronous Execution in Multiagent POMDPs: Reasoning over Partially-Observable Events
This paper proposes a novel modeling approach to problems of multiagent decision-making under partial observability, building on the framework of Multiagent Partial Observable Markov Decision Processes (MPOMDPs). Unfortunately, the size of MPOMDP models (and their solutions) grows exponentially in the number of agents, and agents are required to act in synchrony. In the present work, we show ho...
