- W4232911256 abstract "Infrastructure as a Service (IaaS) Clouds have grown increasingly important. Recent architecture designs support IaaS providers through fine-grain configurability, allowing providers to orchestrate low-level resource usage. Little work, however, has been devoted to supporting IaaS customers who must determine how to use such fine-grain configurable resources to meet quality-of-service (QoS) requirements while minimizing cost. This is a difficult problem because the multiplicity of configurations creates a non-convex optimization space. In addition, this optimization space may change as customer applications enter and exit distinct processing phases. In this paper, we overcome these issues by proposing CASH: a fine-grain configurable architecture co-designed with a cost-optimizing runtime system. The hardware architecture enables configurability at the granularity of individual ALUs and L2 cache banks and provides unique interfaces to support low-overhead, dynamic configuration and monitoring. The runtime uses a combination of control theory and machine learning to configure the architecture such that QoS requirements are met and cost is minimized. Our results demonstrate that the combination of fine-grain configurability and non-convex optimization provides tremendous cost savings (70% savings) compared to coarse-grain heterogeneity and heuristic optimization. In addition, the system is able to customize configurations to particular applications, respond to application phases, and provide near optimal cost for QoS targets." @default.
