A Sensor-Actuator Model for Data Center Optimization

2015

Cloud data centers commonly use virtualization technologies to provision compute capacity with a level of indirection between virtual machines and physical resources. In this paper we explore the use of that level of indirection as …

Online Spike Detection in Cloud Workloads

2015

We investigate methods for detection of rapid workload increases (load spikes) for cloud workloads. Such rapid and unexpected workload spikes are a main cause for poor performance or even crashing applications as the allocated cloud …

2015

High-performance computing (HPC) is focused on providing large-scale compute capacity to scientific applications. HPC schedulers tend to be optimized for large parallel batch jobs and, as such, often overlook the requirements of other scientific applications. …

A Survey on Modeling Energy Consumption of Cloud Applications: Deconstruction, State of the Art, and Trade-Off Debates

2017 · IEEE Transactions on Sustainable Computing

Given the complexity and heterogeneity in Cloud computing scenarios, the modeling approach has widely been employed to investigate and analyze the energy consumption of Cloud applications, by abstracting real-world objects and processes that are difficult …
