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…
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…
Performance-Driven Optimization of Parallel Breadth-First Search
Marati Bhaskar, Raghavendra Kanakagiri
Breadth-first search (BFS) is a fundamental graph algorithm that presents significant challenges for parallel implementation due to irregular memory access patterns, load imbalance…
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…
