High Performance Computing at UCF

1. High Performance Computing atUCF Brian Goldiez, Ph.D. bgoldiez@ist.ucf.edu September, 2008

2. Background • Directed Federal Program • Funded for 2 years • Maximize Campus Participation • Competitive Procurement (7 Bids) • IBM Selected • Machine Named ‘STOKES’ • After Sir George Gabriel Stokes (Mathematician & Physicist) • Participate in the HPC Community • SURAgrid • Supercomputer Conference

3. UCF Objectives • Support Scientific Exploration & Interaction • Science Based M&S • Human Centered M&S • Synergies Between the Above • Build a Diverse Community of Users • Increase System Capabilities • Increase Research Scope & Funding • Attract External Faculty & Users • Become Self Sufficient in 2010

4. Current Management Approach • Research Computing is a Specialize Field • Research Computing Needs to be Professionally Managed (e.g. GSU, Purdue) • We Have Some Unique Opportunities • Interaction in HPC • Real Time Storm Effects on Coastal Areas • Crowd Modeling • Games (Serious & Entertainment) • UCF Can Become a Major Player and Be Viable for Funding • Recommendations: • UCF Centrally Facilitate/Manage Research Computing for Improved Efficiency & Use of Resources • UCF Designate a Person to Become Active in SURA HPC Group & Work With Campus Entities on Rsch Computing • Use Existing Grant Resources to Fund the Initial Effort • Plan for University & External Support and Growth over the Next 3 Years

6. Science Based M&S Usage Nano Technology Civil Engineering Physics Batch Processing Existing Programs (e.g., MatLab) New Data Large Runs Segue to Larger Systems Human Centered M&S Usage IST Army Partnering Industry Interactive Human in the Loop Modeling Human Activity Multi-modal I/O Multi-user No Existing HPC Programs or Data Usage Groupings

7. Interactive Simulation • Needs • Real time capability using fast processors and high-speed interconnects • High fidelity • Low latency/High bandwidth interconnects • Real time I/O • Connection to real world assets • Fixed frame rates (some apps) • Strategies • Message Passing Interface (MPI) or Scalable Link Interface (SLI) • Ltd shared memory processing (SMP) or distributed processing • Interfaces with sensory processors (e.g., interactive visualization, haptics, …) • Scalability in terms of HPC architecture and simulation entities

8. Other Considerations • Let’s remember the ‘human factor’ • How will a user interact with an HPC? • How will multiple users interact with an HPC & maintain coherence of I/O? • How will interim results be gathered? • How can timely and relevant HF experiments be developed to influence the design? • Get developers involved…
