In this report, the RSSAC: • Defines measurements, metrics, and thresholds that root server operators (RSOs) meet to provide a minimum level of performance. The thresholds are based on technical metrics designed to assess the performance, availability, and quality of service that each root server identifier (RSI) provides. The thresholds and the metrics on which they are based are included as...

Modern C++ servers have memory footprints that vary widely over time, causing persistent heap fragmentation of up to 2x from long-lived objects allocated during peak memory usage. This fragmentation is exacerbated by the use of huge (2MB) pages, a requirement for high performance on large heap sizes. Reducing fragmentation automatically is challenging because C++ memory managers cannot move...

Readers of this report will understand the state of the art for training Site Reliability Engineers in both general and domain-specific techniques. This report addresses SRE development and operations practices, along with discussion on how to sustain SRE practices through individual and organizational change. The report will look at training best practices within Google SRE, and also how some...

MLIR - Multi-Level Intermediate Representation compiler infrastructure - was announced at C4ML last year and has since become an official LLVM subproject. It continues to grow as an open community of academic and industry collaborators building common infrastructure for compilers that operate on high level abstractions. In this talk I will focus on uses of MLIR specific to Machine Learning and...
