DISSECT-CF: A simulator to foster energy-aware scheduling in infrastructure clouds
TL;DR: A new IaaS simulation framework, called DISSECT-CF, which introduces concepts such as a unified model for resource sharing and a new energy metering framework with hierarchical and indirect metering options to enable fast evaluation of many scheduling and IAAS internal behaviour related scenarios.
Journal ArticleDOI
Green IT scheduling for data center powered with renewable energy
TL;DR: An approach for scheduling batch jobs with due date constraints, which takes into account the availability of the renewable energy to reduce the need of brown energy and therefore running cost and compared to a traditional scheduler unaware of renewable availability.
