Justin Ratner, CTO of Intel talked about the 3D web and the future of HPC. Hypothesis was that the HPC industry needs to step outside the box and not rely only on the big science funding model. He mentions three fundamental aspects of what he describes as the 3D web:
- Continually simulated
- Multi-view animated
- Immersive and collaborative
Some key issues and technologies mentioned:
- ScienceSim (www.sciencesim.org)
- Demonstrated/discussed several interesting applications
- Bio-diversity and fern population distribution
- Fashion design - cloth simulation
- Discussed several computational challenges in physical simulations
- Physically accurate cloth simulation
- Physically accurate sound generation
- Interoperability is key
- Merging of HPC and Cloud worlds
- Architecture - collision of CPU and GPU
- Larrabee
- Computational co-processor
- Many cores, many threads
- Memory management
- Showed actual code running on hardware
- Ct - High-level data parallel programming (RapidMind)
- CPU-GPU interaction inefficiency - copy over PCI-Exp
- Shared memory between Xeon and Larrabee
- Mine-yours-ours (MYO) sharing
- Demo of physics simulation (soft body dynamics) running on Larrabee using MYO sharing
- SGEMM performance - overclocked Larrabee 1006 GFlops - we think it was real hardware!!!
