Prediction for Distributional Outcomes in High-Performance Computing I/O Variability
Li Xu, Yili Hong, Max D. Morris +1
Although high-performance computing (HPC) systems have been scaled to meet the exponentially-growing demand for scientific computing, HPC performance variability remains a major ch…
Design Strategies and Approximation Methods for High-Performance Computing Variability Management
Yueyao Wang, Li Xu, Yili Hong +6
Performance variability management is an active research area in high-performance computing (HPC). We focus on input/output (I/O) variability. To study the performance variability,…
Sequential Design of Computer Experiments with Quantitative and Qualitative Factors in Applications to HPC Performance Optimization
Xia Cai, Li Xu, C. Devon Lin +2
Computer experiments with both qualitative and quantitative factors are widely used in many applications. Motivated by the emerging need of optimal configuration in the high-perfor…
Prediction of High-Performance Computing Input/Output Variability and Its Application to Optimization for System Configurations
Li Xu, Thomas Lux, Tyler Chang +6
Performance variability is an important measure for a reliable high performance computing (HPC) system. Performance variability is affected by complicated interactions between nume…
Spatial Variable Selection and An Application to Virginia Lyme Disease Emergence
Yimeng Xie, Li Xu, Jie Li +4
Lyme disease is an infectious disease that is caused by a bacterium called Borrelia burgdorferi sensu stricto. In the United States, Lyme disease is one of the most common infectio…
Applications of the Fractional-Random-Weight Bootstrap
Chris Gotwalt, Li Xu, Yili Hong +1
The bootstrap, based on resampling, has, for several decades, been a widely used method for computing confidence intervals for applications where no exact method is available and w…
