Center for High Performance Computing
Research Computing and Data Support for the University Community
In addition to deploying and operating high-performance computational resources and providing advanced user support and training, CHPC serves as an expert team to broadly support the increasingly diverse research computing and data needs on campus. These needs include support for big data, big data movement, data analytics, security, virtual machines, Windows science application servers, protected environments for data mining and analysis of protected health information, advanced networking, and more.
If you are new to the CHPC, the best place to learn about CHPC resources and policies is our Getting Started page.

Weather Classification using Machine Learning
By Greg Furlich
Telescope Array Collaboration, University of Utah
The Telescope Array (TA) cosmic ray observatory located in Millard County, Utah is the largest cosmic ray observatory in the northern hemisphere. It operates 507 surface detectors and 3 Fluorescence Detector (FDs) sites, Black Rock (BR), Long Ridge (LR), and Middle Drum (MD) to detect ultra high energy cosmic rays (UHECR). The FDs operate on clear, moonless nights to best observe the cosmic ray Extensive Air Shower that excites the Nitrogen in the atmosphere. However, sometimes the detector operates when the night is cloudy and this affects the scattering fluorescence light in the atmosphere diminishing our ability to properly reconstruct or simulate the cosmic ray event. In order to flag and remove cloudy weather from the FD data, neural networks were trained on snapshots of the night sky created using the FADC pedestals of each PMT at BR. Starting with simple neural networks and building up complexity, we were able to achieve high accuracy of weather classification and classifying each part allows for better time resolution of the operation night's weather progression.
