Zorro High-Performance Computing (HPC) System

High-Performance Computing rack


Zorro, the AU High-Performance Computing (HPC) System, supports the research enterprise at American University. Researchers who find that standard workstations cannot perform necessary research-related tasks efficiently are encouraged to review HPC system policies and obtain a faculty account or a student account.

The Zorro System provides high-speed parallel/distributed data processing and research-dedicated storage with high input-output capabilities. Please see software and system specifications.

Initial funding for the Zorro System was provided through a National Science Foundation Major Research Instrumentation Program Grant (BCS-1039497), and the Provost’s Office and the College of Arts and Sciences at American University.  


Zorro Research

Zorro supports research projects in all academic units.

The Zorro HPC System was installed in summer 2011. Initial funding for the AU HPC System was generously provided by the National Science Foundation Major Research Instrumentation Program Grant (BCS-1039497); the Office of the Provost; the College of Arts and Sciences; the Office of Information Technology; and the Center for Research, Teaching, and Learning. Ongoing support is provided by AU faculty PIs; the Office of Information Technology; and the Center for Research, Teaching, and Learning.
