ThirstyFLOPS: Water Footprint Modeling and Analysis Toward Sustainable HPC Systems
Yankai Jiang, Raghavendra Kanakagiri, Rohan Basu Roy +1
High-performance computing (HPC) systems are becoming increasingly water-intensive due to their reliance on water-based cooling and the energy used in power generation. However, th…
DarwinGame: Playing Tournaments for Tuning Applications in Noisy Cloud Environments
Rohan Basu Roy, Vijay Gadepally, Devesh Tiwari
This work introduces a new subarea of performance tuning -- performance tuning in a shared interference-prone computing environment. We demonstrate that existing tuners are signifi…
HotSwap: Enabling Live Dependency Sharing in Serverless Computing
Rui Li, Devesh Tiwari, Gene Cooperman
This work presents HotSwap, a novel provider-side cold-start optimization for serverless computing. This optimization reduces cold-start time when booting and loading dependencies…
ForgetMeNot: Understanding and Modeling the Impact of Forever Chemicals Toward Sustainable Large-Scale Computing
Rohan Basu Roy, Raghavendra Kanakagiri, Yankai Jiang +1
Fluorinated compounds, often referred to as forever chemicals, are critical in various steps of semiconductor fabrication like lithography, etching, chamber cleaning, and others. F…
WaterWise: Co-optimizing Carbon- and Water-Footprint Toward Environmentally Sustainable Cloud Computing
Yankai Jiang, Rohan Basu Roy, Raghavendra Kanakagiri +1
The carbon and water footprint of large-scale computing systems poses serious environmental sustainability risks. In this study, we discover that, unfortunately, carbon and water s…
EcoLife: Carbon-Aware Serverless Function Scheduling for Sustainable Computing
Yankai Jiang, Rohan Basu Roy, Baolin Li +1
This work introduces ECOLIFE, the first carbon-aware serverless function scheduler to co-optimize carbon footprint and performance. ECOLIFE builds on the key insight of intelligent…
