Abstract

We wrote “Profiling a WSC” for ISCA 2014 in order to summarize and share our experiences extracting performance information from Google’s datacenter fleet. The paper outlined performance bottlenecks and trends that we observed, both in software and hardware, and sketched out a handful of areas for future research. It was intentionally light on solutions and meant to inspire directions for others’ work. Almost ten years later, we reflect on the predictions the paper made, check back on which ones panned out, and which of the trends have caught on in industry or academia.
