High-End Computing Capability
Computing power to answer NASA's complex science and engineering questions
Visualization System: hyperwall-2
Our in-house developed hyperwall-2 visualization system—one of the largest and most powerful in the world—provides a supercomputer-scale environment to visualize and explore the very large, high-dimensional datasets produced by NASA supercomputers and instruments.
The hyperwall-2 helps researchers display, analyze, and study high-dimensional datasets in meaningful ways, allowing the use of different tools, viewpoints, and parameters to display the same data or datasets.
System Architecture
- Manufacturer: Colfax International
- 128-screen tiled LCD wall arranged in 8x16 configuration; measures 23-ft. wide by 10-ft. high
- 128 nodes
- 2 quad-core AMD Opteron™ 2354 (Barcelona) processors per node
- Processor speed: 2.2 GHz
- Cache: 2 MB for 4 cores
- Memory type: DDR2 registered DIMMs
- 2 GB per core; 16 GB per node
- 9 Tflop/s peak
- Total cores: 1,024 Opteron processor cores
- Total memory: 208 GB of GDDR5 graphics memory
- 128 Nvidia® GeForce® 480 GTX graphics processing units
- Peak processing power: 128 Tflop/s
- Data storage capacity: 1.5 PB
Each of the hyperwall-2's 128 computers can display, process, and share data, allowing a single image to be displayed across all screens, or endless configurations of data can be displayed in selected "cells."
Subsystems
- 2 console nodes
- 4 head nodes (for NFS, PBS®, DHCP, system imaging)
Interconnects
The hyperwall-2 is mounted to Pleiades' Lustre filesystem directly to over InfiniBand® connections. This direct connection means that our visualization experts can read data directly from the Pleiades filesystem for pre- and post-processing on the hyperwall-2, saving many of hours of time in copying very large data files for production visualization work.
Operating Environment
- Operating System: SUSE® Linux®
- Job Scheduler: PBS
- Compilers: C, Intel Fortran
