Agora: Agent and market-based resource management for many-core systems

Resource management approaches are necessary for managing the run-time dynamics originating from application dynamism, platform reliability degradation and changing operating conditions. Existing on-chip resource managers assume that resources are always available and are biased toward application requirements. This paper presents Agora, a distributed resource management framework based on market principles that can proactively decelerate resource unavailability due to reliability degradation. Across the evaluated market models, Agora demonstrates its inherent fairness properties and its capability to efficiently scale to 32 cores. A close comparison indicates that a careful choice between the two models can lead up to 29% relative speedup or 20% relative reduction in resource utilization.
