ALCF Team Receives Best Paper Award at ISAV 2025
A team including ALCF researchers received the Best Paper Award at the SC25 conference’s In Situ AI, Analysis and Visualization Workshop (ISAV 2025). The paper, “In-Transit Data Transport Strategies for Coupled AI-Simulation Workflow Patterns,” was authored by Argonne’s Harikrishna Tummalapalli, Riccardo Balin, and Christine Simpson, along with collaborators Andrew Park, Aymen Alsaadi, and Shantenu Jha of Rutgers University; Andrew E. Shao of Hewlett Packard Enterprise; and Wesley Brewer Oak Ridge National Laboratory. It introduces SimAI-Bench, a tool for prototyping and benchmarking data transport strategies in emerging AI–simulation workflows, and evaluates performance on Aurora across both one-to-one and many-to-one workflow patterns, offering insights into how data movement becomes a critical bottleneck as ensemble sizes grow.
ALCF Staff Members Honored with 2025 Royal Society of Chemistry’s Materials Chemistry Horizon Prize
A team including ALCF staff and led by a longtime ALCF user was awarded the 2025 Royal Society of Chemistry’s Materials Chemistry Horizon Prize: Stephanie L Kwolek Prize. Jacqueline Cole of the University of Cambridge headed an 89-member team that featured ALCF’s Paul Coffman, Adrian Pope, Álvaro Vázquez-Mayagoitia, and Venkat Vishwanath, along with Argonne’s Jeffrey Elam, Liliana Stan, and Angel Yanguas-Gil. Their groundbreaking work leveraged ALCF supercomputers to develop and employ chemistry-aware AI tools and open-source materials databases to accelerate data-driven materials discovery.
ALCF-Led Team Wins Outstanding Paper Award at HPEC 2025
A paper from an ALCF-led team won the Outstanding Paper Award at the IEEE High Performance Extreme Computing Virtual Conference (HPEC 2025). “SYCL for Performance Portability: Application Experience with Coupled Cluster Formalism in Quantum Chemistry on Exascale Systems” demonstrated use of the SYCL programming model to develop portable, high-performance quantum chemistry workloads for exascale systems like the ALCF’s Aurora supercomputer. Lead author Abhishek Bagusetty shared the award with ALCF’s Kevin Harms, along with their Argonne collaborator Álvaro Vázquez-Mayagoitia and coauthors Ajay Panyala of Pacific Northwest National Laboratory and John K. Holmen of Oak Ridge National Laboratory.
ALCF Team Wins 2025 PEARC Conference Series’ Best Visualization Award
“Real-Time Scientific Visualization and Interactive Steering for High-Performance Computing Simulations,” written by a team including ALCF’s Victor Mateevitsi and Mike Papka, received the Best Visualization Award at the 2025 PEARC Conference Series. Lead author Thomas Marrinan of the University of Saint Thomas, along with Andres Sewell and Steve Patruzza of Utah State University, Jifu Tan of Binghamton University, and Argonne’s Dimitrios Fytanidis shared the prize. Their paper bridges the Ascent in situ visualization library with the Trame web-based framework to enable the development of intuitive user interfaces that allow domain experts to steer large-scale HPC simulations without extensive programming knowledge.
Argonne Team Receives SC25 Test of Time Award
A 2005 paper, “The Globus Striped GridFTP Framework and Server,” written by a team from Argonne National Laboratory and the University of Chicago, received the Test of Time Award at the SC25 conference. This influential publication addressed a central HPC challenge of moving massive amounts of data reliably, securely, and with high performance. The striped GridFTP framework enabled parallel transfers across multiple servers and clients, laying the foundation for nearly two decades of scientific discovery across data-intensive fields, such as cosmology, particle physics, and genomics. Lead author William Allcock of the ALCF shared the award with Argonne’s John Bresnahan and Ian Foster, along with their University of Chicago collaborators Rajkumar Kettimuthu, Michael Link, Catalin Dumitrescu, and Ioan Raicu.
ALCF Director Named Argonne Distinguished Fellow
In 2025, ALCF Director Michael Papka was named an Argonne Distinguished Fellow. Papka has been with Argonne for more than 35 years, during which time he has made major contributions to high-performance computing leading the ALCF and serving as deputy associate laboratory director for Computing, Environment, and Life Sciences (CELS).
ALCF Postdoc Named Margaret Butler Fellow
ALCF postdoctoral researcher Snigdaa Sethuram, a computational astrophysicist, was named the Margaret Butler Fellow in Computational Science. Sethuram specializes in developing machine learning models to accelerate complex simulations of cosmic phenomena, ranging from star formation to radiative transfer.
ALCF Researchers Honored with Outstanding Postdoctoral Performance Awards
ALCF postdoctoral researchers Shilpika S and Krishna Teja Chitty-Venkata received the Argonne Outstanding Postdoctoral Performance Award, honoring their research contributions, problem-solving, leadership, and impact on Argonne and DOE missions.
