Data Analysis
Data analysis transforms large-scale simulation and experimental data into scientific insight. At DOE scale, analysis capabilities must operate efficiently on distributed and heterogeneous computing systems, often while data is still being generated. Expertise in data analysis spans in situ and streaming analytics, feature detection and tracking, topological analysis, statistical characterization, and production visualization. These methods enable researchers to identify important phenomena, quantify uncertainty, explore large parameter spaces, and accelerate scientific discovery while reducing the costs associated with storing and moving massive datasets. The RAPIDS portfolio provides capabilities in scalable scientific visualization, feature extraction, topological analysis, workflow-integrated analytics, and in situ processing. These technologies allow scientists to analyze data during execution, detect and track critical features, characterize complex behaviors, and interactively explore datasets that would otherwise be too large to manage using traditional post-processing approaches. The RAPIDS technology supports applications ranging from fusion energy and climate science to particle physics and materials research.

Data Management
Data management includes the method design, software, and infrastructure required to efficiently store, move, organize, access, and curate scientific data throughout its lifecycle. As simulations, instruments, and AI workflows produce increasingly large and distributed datasets, effective data management becomes essential for scientific discovery. Key capabilities include scalable I/O, data streaming, workflow orchestration, campaign data management, metadata services, data movement across storage hierarchies, and performance monitoring of data access patterns.The RAPIDS portfolio provides technologies for high-performance I/O, workflow-enabled data orchestration, campaign-scale data management, and understanding application data access behavior. These capabilities help scientific teams efficiently move data between memory, storage, analysis services, and AI workflows while maintaining scalability across leadership computing facilities. RAPIDS technology enables performance characterization and optimization of scientific data workflows, helping researchers reduce bottlenecks, improve resource utilization, and support increasingly integrated simulation, experimental, and AI-driven campaigns.

AI for Science
AI for Science combines artificial intelligence, advanced mathematics, scientific computing, and domain knowledge to accelerate scientific discoveries. It is especially important for DOE because the Department brings together leadership-class computing, major experimental facilities, advanced instruments, and mission-scale datasets. Connecting these assets through AI can create an integrated environment in which models, simulations, experiments, and instruments are coordinated in closed-loop workflows. This supports the Genesis Mission objective of increasing research productivity and shortening the path from scientific question to validated result and practical impact.
Our combined portfolio spans the scientific AI lifecycle. It includes physics-aware surrogate and reduced-order models that accelerate expensive simulations; generative, geometric, and graph-based methods for modeling complex systems; uncertainty quantification, inverse design, optimization, digital twins, and learning-enabled control. We also develop agentic workflows that can plan multistep investigations, invoke simulations and analysis tools, interpret results, and adapt subsequent actions. Another distinctive capability is training, evaluating, and deploying scientific foundation and multimodal models at leadership scale---including language, spatiotemporal, time-series, and multimodal models, with demonstrated campaigns on DOE leadership computing platforms.

Application Performance
For the past 25 years, SciDAC's performance engineering and optimization efforts have translated the exponential increases in system performance spanning the tera-, peta-, and exascale eras into commensurate increases in application and workflow performance. This capability is delivered through a tight loop that integrates performance modeling and analytical tools, advances in communication libraries and runtimes, and partnership-focused performance engineering efforts that see our cohort of HPC experts immerse themselves in the complexity of each domain's computational science and seamlessly meld their decades of trustworthy performance engineering with the accelerated productivity of AI coding agents. Building decades of research and development in performance tools, performance optimization, performance and energy modeling and analysis, autotuning, etc., SciDAC experts develop and deploy techniques, technologies, and tools to enhance high performance, energy efficiency, portability, and productivity. To showcase and jump start partnership and community adoption of novel computer science, data, AI/ML, and applied math techniques, we can help develop proxy applications. Finally, we explore and develop core capabilities in the use and analysis of emerging AI and neuromorphic accelerators and concepts to address SciDAC partnership needs.

Software Quality and Sustainment
Software quality and sustainment encompass the engineering practices, metrics, and community investments that keep scientific software correct, reliable, and maintainable across its lifetime. As DOE science grows more dependent on complex, long-lived software running on rapidly evolving leadership-class architectures, deliberate attention to quality and sustainment is essential to protect the substantial investment these codes represent and to ensure that scientific results remain trustworthy and reproducible. Expertise in this area spans the adoption of software engineering best practices---version control, continuous integration, automated testing, documentation, and secure release processes---together with objective software metrics that make quality measurable, and the community development and training activities that grow and retain a skilled contributor base. These capabilities allow scientific teams to catch defects early, quantify and steadily improve the health of their codebases, and lower the barriers for new developers to contribute. The RAPIDS portfolio provides hands-on stewardship of widely used software products, helping teams establish CI testing, improve code coverage and static analysis, and adopt community standards such as OpenSSF scorecards. RAPIDS also develops shared, metric-based frameworks---assessing impact, sustainability, and quality---that let projects benchmark their practices and demonstrate progress over time. Through targeted mentoring, documentation, and training, RAPIDS helps DOE teams deliver dependable capabilities today while building the practices needed to sustain them well into the future.
