  • Tailored services for unique requirements of a given research initiative

The Catalyst Team:

  • Provides a "jump-start" in the use of ALCF resources
  • Aligns the availability of ALCF resources with the needs of the project team
  • Establishes a spirit of collaboration to maximize the value that ALCF can bring to our project partners

Performance Engineering

The mission of the Performance Engineering group is to ensure the effective use of applications on ALCF systems and emerging systems by assessing and improving the algorithms used by the applications and techniques used to implement those algorithms. This team's efforts are driven by the needs of the applications.

ALCF Performance Engineers have extensive expertise and are involved in:

  • Application Scaling and single core optimizations
  • Performance modeling and projections
  • Performance tools and libraries collaborations
  • Performance benchmarks development
  • Programming models and communication software
  • Parallel I/O optimizations
  • Computer architectures
  • Standard organizations in programming languages and programming models

Data Analytics and Visualization Team 

The Data Analytics and Visualization team has expertise in tools and methods for high-performance post processing of large datasets, interactive data exploration, batch visualization, and production visualization. 

Team members help users with their visualization and analysis needs using ALCF high-performance resources and a suite of tools maintained for these purposes, including:

  • Production tools for high performance visualization (ParaView, VisIt) 
  • Analysis tools (R, Octave) 
  • Presentation graphics (ImageMagick, ffmpeg) 

Team members also have expertise and assist users with additional tools which are not generally available on ALCF resources, including:

  • Analysis tools (MATLAB) 
  • Presentation graphics (PowerPoint, Keynote, Adobe Premiere) 

The ALCF Data Analytics and Visualization team has strong connections to Argonne’s Mathematics and Computer Science research and development in the area of visualization and analysis.
