In high-performance computing (HPC), modern supercomputers typically provide exclusive computing resources to user applications. Nevertheless, the interconnect network is a shared resource for both inter-node communication and across-node I/O access, among co-running workloads, leading to inevitable network interference. In this study, we develop MFNetSim, a multi-fidelity modeling framework that enables simulation of multi-traffic simultaneously over the interconnect network, including inter-process communication and I/O traffic. By combining different levels of abstraction, MFNetSim can efficiently co-model the communication and I/O traffic occurring on HPC systems equipped with flash-based storage. We conduct simulation studies of hybrid workloads composed of traditional HPC applications and emerging ML applications on a 1,056-node Dragonfly system with various configurations. Our analysis provides various observations regarding how network interference affects communication and I/O traffic.<br><br>

On July 16, 2025 UIC&rsquo;s Computer Science Department&rsquo;s new building - Computer Design Research and Learning Center (CDRLC) opened at 850 W. Taylor Street. The 135,000-square-foot building houses EVL&rsquo;s Arcade, also known as the Data Observation and Computation Collaboratory (DOCC). Arcade is a visual data science instrument for UIC science and engineering research and research training - a digital Project Room that enables domain scientists and computer scientists to collaborate on real-world problems by providing them with high-performance computing, high-resolution displays, and sophisticated Artificial Intelligence (AI), data analytic, data simulation, image processing, visualization, and virtual-reality software and services.<br><br>
13+
Arcade provides on-site computing with adequate support, and it provides collaboration software services. It is a configurable computing environment that prioritizes real-time, interactive, collaborative, data-intensive applications, but can be scheduled off-hours for batch-mode processing. Users can execute codes faster, apply more sophisticated analytics to large-scale problems, gain greater insights, and open new avenues of research. The Arcade's collaboration software lets researchers either interact locally with colleagues using the display walls or video-teleconference while simultaneously sharing and interacting with their data on the large displays, which remote viewers can also access online.

SAGE3, the Smart Amplified Group Environment, is the next-generation, “human-in-the-loop” visualization and collaboration platform, which uses artificial intelligence (AI) capabilities to serve as a user’s “co-pilot” to autonomously manage and link disparate datasets and orchestrate services. It is being developed by the Laboratory for Advanced Visualization & Applications (LAVA) and the Hawaii Data Science Institute (HI-DSI) at University of Hawaii at Manoa (UHM), the Electronic Visualization Laboratory (EVL) at University of Illinois Chicago (UIC), and the Center for Human-Computer Interaction (CHCI) at Virginia Tech (VT).
13+
14+
SAGE3 held its annual AHM at EVL from July 23-25, 2025. LAVA, EVL and CHCI team members participated either locally or remotely, and were joined by long-time collaborators Argonne Leadership Computing Facility (ALCF) at Argonne National Laboratory and the Academy for Creative Media (ACM) at University of Hawaii.<br><br>
15+
Though distributed, the team had fruitful discussions and brainstorming sessions, which were greatly enhanced by using SAGE3 on EVL&rsquo;s Cyber-Commons display wall to share documents, webpages, stickie notes, etc. They also utilized SAGE3&rsqu;s AI capabilities to search online for information, summarize documents, etc. Given this is the last year of the current NSF SAGE3 award, discussions also centered on the future. Topics discussed:<br><br>
16+
* Listing both work to be completed, and aspirations for how SAGE3 can be an even more productive collaboration and visualization tool.<br>
17+
* Discussions of how technology is advancing and what will be important over the next five years.<br>
18+
* Deciding what new user communities might benefit from SAGE3.<br>
19+
* Discussions on how AI can further help with collaboration, documentation, spatialization of content, etc.<br>
20+
* Looking at future opportunities and potential NSF programs to pursue.<br><br>
21+
<i>SAGE3 receives major support from the National Science Foundation (NSF), awards #2004014 (UHM), #2003800 (UIC) and #2003387 (VT).</i>

The VR project <i>Fulfillment: a field guide to the logistical city</i>, is a multi-year research project developed at the Electronic Visualization Laboratory (EVL) at the University of Illinois Chicago (UIC) in collaboration with the Anthropology Department at the University of Chicago. The project was enabled through a unique collaboration between anthropologists, designers, and other social scientists from several research institutions spanning the U.S., Europe, and Asia, with support from the National Science Foundation. This proposal is for a public exhibition of the <i>Fulfillment project</i> in the CAVE2 VR Environment as part of the Demos and Exhibitions track during the ACM Hypertext 2025 Conference in Chicago to be held September 15-18.<br><br>
20+
Project Fulfillment brings VR technology to the forefront of anthropological research to engage participants in guided first-hand observation of the hidden aspects of logistics and the behind-the-scenes effects of supply chain capitalism on ecology, labor and socio-economic well-being. This immersive experience unfolds the increasingly pervasive yet often obscured ways in which the infrastructural and operative dimensions of commercial logistics are reshaping the way we work, live, and relate to each other and to our environments.<br><br>
21+
Participants enter a virtual narrative environment by initially selecting an object of &ldquo;fulfillmentrdquo; from an online graphic display (GUI) of everyday consumer items - such as a teddy bear, stationery, or a healthcare product. The selection of the item serves as an entry point into a deeper exploration of the hidden costs and consequences of commercial logistics. Using a button-equipped wand in the immersive CAVE2 VR system, participants navigate through ten interconnected scenes - including a cityscape, data center, warehouse zones, modern cemetery, prairie land, and military ruins - each revealing layers of ecological, social, historical, and economic entanglements that shape global supply chains.<br><br>
22+
Interactive objects embedded within each scene act like hyperlinks: when activated, they visually tear open the environment to expose new narratives and landscapes connected to the selected item, inviting participants to reflect on the often-invisible infrastructures and labor that sustain contemporary consumer worlds. This immersive system transforms data-driven insights from fieldwork and archival research into ethnographic spatial storytelling, giving multi-sensorial form to complex systems and fostering critical reflection on the ethics and impacts of global commerce.<br><br>
23+
Through this project, we seek to illuminate the hidden dimensions of global supply chain infrastructures - tracing their profound effects on labor, consumption, well-being, and ecological systems. By leveraging the immersive power of virtual reality, Fulfillment not only expands the methodological toolkit of anthropological fieldwork but also enhances public engagement with complex, often obscured, socio-technical systems. This work catalyzes interdisciplinary collaboration across anthropology, design, science, and engineering, while fostering novel multi-modal pathways for educating emerging scholars and engaging broader public beyond academia. Ultimately, the project lays the groundwork for a more inclusive and sensorially rich future for anthropological research, its collaborative possibilities, broader impact, and accessibility.
