Computer Visualization Facility
Background
• Advanced Research Computing section started as HPC support group
• Funded from research vote (off-the-top)
• Charged with increasing number of users and range of disciplines
• Founded Computer Visualization Facility as one means to achieve this
Rationale
• Scientific Visualization– Introduce scientists to better graphics– Better presentation– Better understanding
• Rendering and Animation– Artists using HPC
• Multimedia test facility
The proposal
The Reality
The Toys
VisionStation Plasma Screen
Case Study
• Theoretical Physics – Coupled-channel Collective Model
– Elastic scattering of Neutrons from Carbon nuclei
• Intensive Numerical Integration– Started as a HPC collaboration
– Model has ~10 parameters
– 1000 pts takes ~20 mins on 1 APAC cpu

New CVF proposal
• We thought we might get some space in one of the new buildings in our South Precinct.
• This was part of our presentations
• We didn’t get that space…
