The Mnemos resource management and scheduling architecture uses portfolio scheduling, topology-aware virtual-resource management, and state information to self-adapt to significant workload changes and to analyze risks. Simulations with real-world workload traces reveal the potential for significant cost savings.
In this paper we present the scaling of BTWorld, our MapReduce-based approach to observing and analyzing the global BitTorrent network which we have been monitoring for the past 4 years. BTWorld currently provides a comprehensive and complex set of queries implemented in Pig Latin, with data dependencies between them, which translate to several MapReduce jobs that have a heavy-tailed distribution...
The commoditization of big data analytics, that is, the deployment, tuning, and future development of big data processing platforms such as MapReduce, relies on a thorough understanding of relevant use cases and workloads. In this work we propose BTWorld, a use case for time-based big data analytics that is representative for processing data collected periodically from a global-scale distributed system...
