Nowadays, large computing clusters are executing highly heterogeneous bursty workloads with different priorities, resource demands, and performance objectives. As the schedulers control the class-specific performance by evictions, a noteworthy amount of the computing resources are wasted by the lost executions of the evicted tasks. This paper presents a system model with a slot-based priority scheduler...
In data centers, many tasks (services, virtual machines or computational jobs) share a single physical machine. We propose a new resource management model for such colocation. Our model uses two parameters of a task -- its size and its type -- to characterize how a task influences the performance of the other tasks allocated on the same machine. As typically a data~center hosts many similar, recurring...
This paper identifies workload and platform heterogeneity as an important feature that needs to be modeled and exploited for optimizing for performance and energy efficiency. We start by understanding how frequently are computer jobs submitted to an industrial-scale data center and discover/explain two patterns with respect to the inter-arrival time (IAT) of job requests. Based on these, a novel generative...
