cxHPC: Center of Excellence in High Performance Computing

Project summary

The efficient use of modern supercomputers is closely connected with an extensive and qualified user training and user support. Thus, the aim of the project cxHPC (formerly known as BAUWIHR) is to provide a center of excellence for scientific supercomputing at the Friedrich-Alexander University of Erlangen-Nuremberg.

cxHPC addresses the following tasks:

  • HPC support: Programming, Debugging, Optimization of HPC codes. Provide test accounts to all major german supercomputer centers for testing and optimization
  • HPC training: Organize HPC tutorials and HPC lectures for students and users
  • HPC information: Present information about the latest development in HPC: new architectures, programming models, available resources, global trends,....

KONWIHR funding and follow-up projects

  • initial KONWIHR funding: 01/2000 - 12/2003
  • follow-up funding: onging funding through External link: STMWFK and External link: FAU.
  • OMI4papps continues the work of cxHPC with a special focus on highly parallel applications
