  1. Visualization Support for XSEDE and Blue Waters DOE Graphics Forum 2014

  2. Organization Advanced Digital Services

  3. Advanced Digital Services • Common Blue Waters and XSEDE functions • User support (including visualization) • Network infrastructure • Storage • Operations • Support for future NCSA efforts • Resources managed by service level agreements

  4. Advanced Digital Services • Visualization Group – Support for data analysis and visualization. • XSEDE • Dave Bock • Mark VanMoer • Blue Waters • Dave Semeraro • Rob Sisneros

  5. Visualization Support • Software • Paraview • VisIt • YT • IDL (coming soon) • (ncview, matplotlib, ffmpeg, …) • Opengl driver on Blue Waters XK nodes • Direct user support • Data analysis / custom rendering. • Scaling analysis tools / parallel IO

  6. XSEDE

  7. Blue Waters Stellar magnetic and temperature field Supernova ignition bubble Atmospheric downburst

  8. Blue Waters Compute System. • System • Total Peak Performance 13.34 PF • Total System Memory 1.476 PB • XE Bulldozer Cores* 362,240 • XK Bulldozer Cores* (CPU) 33,792 • XK Kepler Accelerators (GPU) 4,224 • Interconnect • Architecture 3D Torus • Topology 24x24x24 • Compute nodes per Gemini 2 • Storage • 26.4 PB • Bandwidth > 1 TB/sec

  9. Blue Waters Visualization System. • System • Total Peak Performance 13.34 PF • Total System Memory 1.476 PB • XE Bulldozer Cores* 362,240 • XK Bulldozer Cores* (CPU) 33,792 • XK Kepler Accelerators (GPU) 4,224 • Interconnect • Architecture 3D Torus • Topology 24x24x24 • Compute nodes per Gemini 2 • Storage • 26.4 PB • Bandwidth > 1 TB/sec

  10. Blue Waters Allocations • GLCPC – 2% • PRAC – over 80% • Illinois – 7% • Education – 1% • Project Innovation and Exploration • Industry

  11. GLCPCGreat Lakes Consortium for Petascale Computing GLCPC Mission: “…facilitate and coordinate multi-institutional efforts to advance computational and computer science engineering, and technology research and education and their applications to outstanding problems of regional or national importance…” • 2% allocation • 501c3 Organization* • 28 Charter members** • Executive Committee • Allocations Committee • Education Committee *State 501c3 filing complete, federal filing in progress ** 28 Charter members represent over 80 universities, national laboratories, and other education agencies

  12. Industry S&E Teams • Industry can participate in the NSF PRAC process • 5+% allocation can dedicated to industrial use • Specialized support by the NCSA Private Sector Program (PSP) staff • Blue Waters staff will support the PSP staff as needed • Potential to provide specialized services within Service Level Agreements parameters • E.g. throughput, extra expertise, specialized storage provisions, etc. High interest shared by partner companies in the following: • Scaling capability of a well-known and validated CFD code • Temporal and transient modeling techniques and understanding. Two example cases under discussion: • NASA OVERFLOW at scale for CFD flows • Temporal modeling techniques using the freezing of H2O molecules as a use case and as a reason to conduct both large-scale single runs and to gain significant insight by reducing uncertainty.

  13. Real Improvement in Time to Solution • 10,5603 grid Inertial confinement fusion (ICF) calculation with multifluid PPM • Rendered 13,688 frames at 2048x1080 pixelsv4 panels per view & 2 views per stereo image @ 4096x2160 pixels. Stereo movie is 1711 frames
