Will present our experience and results, for mixed workload management, in a share nothing architecture,large MPP database. We use a driver next to Linux, and the support of CFS and Hard limits to accomplish our goals.We have built a database priority scheduler on top of CFS, using a group hierarchy, flexible enough to satisfy all prioritization needs of complex mixed workloads. We have also used Hard Limits to offer COD and partitioning of the system. This innovative work validates the benefits and extensibility of the CFS as applied in the business world.We will present our results and performance. Our paper fits very well in the suggested topics for the conference: Optimization of Linux in enterprise environments, Case studies on impressive Linux performance in data centers or embedded computing, KernelThe presentation is intended for core developers and IT professionals.
