BOPS, Not FLOPS! A New Metric, Measuring Tool, and Roofline Performance Model For Datacenter Computing.

2018

The past decades witness FLOPS (Floating-point Operations per Second), as an important computation-centric performance metric, guides computer architecture evolution, bridges hardware and software co-design, and provides quantitative performance number for system optimization. However, for emerging …

Workload-Adaptive Configuration Tuning for Hierarchical Cloud Schedulers

2019 · IEEE Transactions on Parallel and Distributed Systems

Cluster schedulers provide flexible resource sharing mechanism for best-effort cloud jobs, which occupy a majority in modern datacenters. Properly tuning a scheduler's configurations is the key to these jobs' performance because it decides how to …
