Using Janus Supercomputer for Hydrologic Problems

            Abstract

The Research Computing Center at CU-Boulder offers several high performance computing 
options including its supercomputer, Janus. Since many water resources researchers on 
campus require significant computing resources, using Janus to meet their needs could be 
advantageous. In this talk, we will provide students and faculty with a straightforward 
overview of Janus, including practical instructions on gaining access to Janus, submitting 
computing jobs, and receiving job outputs. We will also discuss three example research 
projects in the department that have used Janus, including:
1. An application of Bayesian hierarchical modeling for improving high-resolution 
satellite-derived estimates of precipitation in regions of complex terrain, using R
2. Use of chaotic dynamics and the finite time Lyapunov exponents to gauge how Lagrangian 
coherent structures within turbulent flows can increase reaction rate between two initially 
distant scalars.
3. Multi-objective optimization of engineered injection and extraction systems to improve 
in situ remediation of groundwater
