    Application of Edge-to-Cloud Methods Toward Deep Learning
    (IEEE, 2022-10) Choudhary, Khushi; Nersisyan, Nona; Lin, Edward; Chandrasekaran, Shobana; Mayani, Rajiv; Pottier, Loic; Murillo, Angela P.; Virdone, Nicole K.; Kee, Kerk; Deelman, Ewa; Library and Information Science, School of Computing and Informatics
    Scientific workflows are important in modern computational science and are a convenient way to represent complex computations, which are often geographically distributed among several computers. In many scientific domains, scientists use sensors (e.g., edge devices) to gather data such as CO2 level or temperature, that are usually sent to a central processing facility (e.g., a cloud). However, these edge devices are often not powerful enough to perform basic computations or machine learning inference computations and thus applications need the power of cloud platforms to generate scientific results. This work explores the execution and deployment of a complex workflow on an edge-to-cloud architecture in a use case of the detection and classification of plankton. In the original application, images were captured by cameras attached to buoys floating in Lake Greifensee (Switzerland). We developed a workflow based on that application. The workflow aims to pre-process images locally on the edge devices (i.e., buoys) then transfer data from each edge device to a cloud platform. Here, we developed a Pegasus workflow that runs using HTCondor and leveraged the Chameleon cloud platform and its recent CHI@Edge feature to mimic such deployment and study its feasibility in terms of performance and deployment.

    Blueprint: Cyberinfrastructure Center of Excellence
    (Zenodo, 2021-03) Deelman, Ewa; Mandal, Anirban; Murillo, Angela P.; Nabrzyski, Jarek; Pascucci, Valerio; Ricci, Robert; Baldin, Ilya; Sons, Susan; Christopherson, Laura; Vardeman, Charles; Ferreira da Silva, Rafael; Wyngaard, Jane; Petruzza, Steve; Rynge, Mats; Vahi, Karan; Whitcup, Wendy R.; Drake, Josh; Scott, Erik; Library and Information Science, School of Informatics and Computing
    In 2018, NSF funded an effort to pilot a Cyberinfrastructure Center of Excellence (CI CoE or Center) that would serve the cyberinfrastructure (CI) needs of the NSF Major Facilities (MFs) and large projects with advanced CI architectures. The goal of the CI CoE Pilot project (Pilot) effort was to develop a model and a blueprint for such a CoE by engaging with the MFs, understanding their CI needs, understanding the contributions the MFs are making to the CI community, and exploring opportunities for building a broader CI community. This document summarizes the results of community engagements conducted during the first two years of the project and describes the identified CI needs of the MFs. To better understand MFs' CI, the Pilot has developed and validated a model of the MF data lifecycle that follows the data generation and management within a facility and gained an understanding of how this model captures the fundamental stages that the facilities' data passes through from the scientific instruments to the principal investigators and their teams, to the broader collaborations and the public. The Pilot also aimed to understand what CI workforce development challenges the MFs face while designing, constructing, and operating their CI and what solutions they are exploring and adopting within their projects. Based on the needs of the MFs in the data lifecycle and workforce development areas, this document outlines a blueprint for a CI CoE that will learn about and share the CI solutions designed, developed, and/or adopted by the MFs, provide expertise to the largest NSF projects with advanced and complex CI architectures, and foster a community of CI practitioners and researchers.

    Broadening student engagement to build the next generation of cyberinfrastructure professionals
    (Association for Computing Machinery, 2023) Murillo, Angela P.; Brower, Don; Hossain, Sarowar; Kee, Kerk; Mandel, Anirban; Nabrzyski, Jarek; Scott, Erik; Ewing, Rodney; Deelman, Ewa
    The CI Compass Fellowship Program (CICF) was developed to broaden undergraduate student participation in cyberinfrastructure (CI) research, development, and operations. CICF is a distinctive program for undergraduate students pursuing studies in computer science, information science, data science, and other related fields. During year one of the program, CICF had six students participate from two institutions. During year 2 of the program, CICF had fourteen students participate from nine institutions. This poster provides details of the CICF program development and summarizes the impact of the first two years.

    Broadening Student Engagement To Build the Next Generation of Cyberinfrastructure Professionals

    Broadening Student Participation in Cyberinfrastructure Research and Development
    (Association for Computing Machinery, 2022) Murillo, Angela P.; Deelman, Ewa; Nabrzyski, Jarek; Pottier, Loïc
    This poster presents preliminary observations from the pilot year of a CI Compass Fellowship Program (CICF) that was created to broaden student participation in cyberinfrastructure research and development. CICF is part of the CI Compass project, which is the National Science Foundation (NSF) Cyberinfrastructure Center of Excellence, created to provide support and enhance the data lifecycle of NSF Major Facilities (MFs) [1]. MFs are the largest-scale scientific efforts that the NSF supports and are highly diverse, have heterogeneous data, and a wide range of cyberinfrastructure for capturing, processing, archiving, and disseminating data, as well as providing access to sophisticated instruments and computational capabilities. MFs span many science domains, including astronomy, climate, ecology, natural hazard, ocean science, physics, and seismology [2]. Due to the complexity of the cyberinfrastructure and data that supports MFs, it is critical that we create educational opportunities for students interested in pursuing a career in this specialized cyberinfrastructure that supports large-scale science. The CICF program aims to provide students the opportunity to learn about cyberinfrastructure development and MFs, develop cyberinfrastructure-related skill sets important to the work of MFs, and engage directly with the MF CI professionals.
