Researcher's paper named best at IEEE conference

July, 2007 — A publication on a self-tuning hierarchical aggregation system by HP Labs researcher Praveen Yalagandula has received the best paper award at the first IEEE International Conference on Self-Adaptive and Self-Organizing Systems (SASO 2007).

The paper, co-authored by Mike Dahlin of the University of Texas (Austin), proposes a novel self-tuning approach for deciding aggregation aggressiveness in large-scale systems based on observed read and write patterns. Scalable aggregation is a building block for many large-scale distributed applications, including monitoring and resource-scheduling.
