“Scheduling with Multiple Resource Types in Cloud Datacenters”

Venue: S2|02 room C110 (Robert-Piloty building, Hochschulstr. 10, 64289 Darmstadt)


In the age of big data, it has been the norm for cloud datacenters to run data analytic applications at a large scale. Yet, as multiple applications share resources in these datacenters, it is important to design scheduling disciplines for datacenter resources to be shared in a fair and efficient manner. In this talk, I will present a new class of scheduling disciplines that are specifically designed for sharing multiple resource types in cloud datacenters.

I will first discuss how multiple resource types are to be shared in space, and present a new design that allocates resources to applications by scheduling their computing tasks onto datacenter nodes. I will then focus on the problem of sharing resources over time, and present a new scheduler to multiplex application flows in software routers, sharing both CPU and link bandwidth. In both contexts, I will open with examples, explore their theoretical underpinnings related to fairness and efficiency, and! conclude with challenges and observations in real-world implementations.
