InterACTWEL Cyberinfrastructure: Enabling Long-term AI-driven Decision Support for Adaptive Management of Water, Energy, and Land Resources in Watershed Communities
Presenter(s): Meghna Babbar-Sebens (Oregon State University) Samuel Rivera (Oregon State University) Eroma Abeysinghe (Indiana University) Eric Coulter (Indiana University)
Cyberinfrastructure serves as backbone to many of the complex and data-intensive computational analyses typically conducted for climate change impact assessment and decision support. However, cyberinfrastructure research in the recent past has been primarily focused on supporting the needs of researchers via support of networking, storage, standards, middleware, and computation capabilities. Adaptation to climate change in watershed communities will require long-term interactions with stakeholders for coordination of context-sensitive decisions, as conditions evolve over time. This means that application of Artificial Intelligence (AI) in adaptation research will need to consider the social-physical and dynamic nature of climate-change resilience problems in order to be decision-relevant. This has necessitated a broader vision for the role of AI-ready cyberinfrastructure in supporting multi-years stakeholder engagement for climate-change resilience. In this presentation, we present a novel, use-inspired, cyberinfrastructure InterACTWEL, which is being created to support longitudinal collaboration between researchers and decision makers on stakeholder-driven planning of adaptation to climate-change impacts in local watershed communities. We demonstrate how InterACTWEL cyberinfrastructure is being used to support AI-assisted and stakeholder-driven planning of water supply resilience in a testbed local community within the Columbia River Basin.

COVID-19 Drug Repurposing Guidance using Fragment Molecular Orbital (FMO) Calculations

In this talk, we share our experiences and updates of a COVID-19 HPC Consortium project (https://covid19-hpc-consortium.org/projects/5eb5c8784c0571007b307650). Motivated by the need to rapidly identify drugs that are likely to bind to targets implicated in SARS-CoV-2, the virus that causes COVID-19, we present a framework for Fragment Molecular Orbital (FMO) calculations to speed up quantum mechanical calculations that can be used to explore structure-energy relationships in large and complex biomolecular systems. These calculations are still onerous, especially when applied to large sets of molecules.. We will share our XSEDE ECSS collaboration in assisting with cyberinfrastructure aspects, mechanisms and user interfaces that manage job submissions, data retrieval, and data storage for the FMO calculations. The talk will summarize how we used the Apache Airavata science gateway platform to apply FMO calculations to complexes formed between SARS-CoV-2 Mpro (the main protease in SARS-CoV-2) and 2820 approved and experimental drugs in a drug-repurposing library. The talk will highlight Airavata's job submission and monitoring enhancements to support static and parallel parameter sweeping capability on remote compute clusters across a batch of input data. We will discuss integration of a data parsing workflow to capture, filter out, and validate the enriched metadata from the outputs. Finally, we will discuss generalization of the extensions made in support of large-scale FMO calculations for SARS-CoV-2 Mpro-drug complexes and potential use in other biomolecular systems.

Leveraging Augmented Reality to Enhance Remote Collaboration
Presenter(s): Max Collins (UC Irvine)
Augmented Reality (AR) is a medium that gives people the ability to engage with digital information in ways that deviate from more traditional HCI methods (e.g. WIMP user interfaces). Remote work experiences leveraging teleconferencing are becoming increasingly prevalent as many are working together remotely in higher frequencies. In this talk we cover our investigation into the ways that AR can support efforts to work together across distance, and how invoking AR may create a sense of joint focus and engagement beyond what traditional remote collaboration tools afford. We outline the design process of an AR add-on to teleconferencing tools (e.g. Zoom) that allows participants to interact with one another around digital assets in AR, and share objects with one another through the screen. We investigate the use cases of this tool and describe the evaluation methods and preliminary user testing results of this system.
Best Practices for Research Software Engineers
Presenter(s): Rudi Eigenmann (University of Delaware)
The Xpert Network brings together teams and individuals that support domain scientists in developing, optimizing and running computational and data-intensive applications. One goal is to develop best practices. In this talk I will summarize initial results. They include both software engineering advice and recommendations for team organization and collaboration. The results also include experiences with tools that can accelerate the work of research software engineers. A particular emphasis will be on practices that differ from those applicable in a general software engineering context.

HPC for epidemic modeling with limited data: COVID-19 case studies
Presenter(s): Kelly Pierce (TACC)
The novel coronavirus (SARS-CoV-2) emerged in late 2019 and spread globally in early 2020. Initial reports suggested the associated disease, COVID-19, produced rapid epidemic growth and caused high mortality. As the virus sparked local epidemics in new communities, health systems and policy makers were forced to make decisions with limited information about the spread of the disease. The UT COVID-19 Modeling Consortium formed in response to the urgent need for increased situational awareness and developed a library of COVID-19 models to project infections and healthcare burdens. These models were used to inform policy decisions in the city of Austin, Texas and as part of the CDC COVID-19 mortality and infection model ensembles. Now one year into the pandemic, the Consortium has expanded the scope of its work to include estimates of infection introductions in schools, statistically informed guidelines for genomic surveillance to detect novel variants, and equitable vaccine distribution. As an early partner in the Consortium, the Texas Advanced Computing Center (TACC) has provided support in software development, data management, and long-term modeling infrastructure development. This talk will overview the joint work of the Consortium and TACC, with an emphasis on the impact of limited data availability in epidemiological modeling and the role of high-performance computing in supporting fast turn-around of time-sensitive results.
