  1. Your Results From Disk to Device(Preview) Amit Chourasia Mona Wong-Barnum Michael L. Norman San Diego Supercomputer Center, UCSD Presented at: XSEDE 13, San Diego, CA, Jul 23, 2013

  2. Stream Encode Explore Disseminate My Experiments

  3. Computation Cycle Abstract ? Monitor? Validate?

  4. Monitoring • DerivedProducts • Abstraction • Validation

  5. Direct Access • Not All Members Have HPC Access • Direct Sharing • Security Implications On HPC • DerivedProducts

  6. Concise derived products • Plots & Text Documents • Image Sequences & Videos Share with the research group • Download derived products • Share with collaborators • Email snippets • Set up a webpage • Add content • Email

  7. Derived Visual Content Survey Derived content for a single research group in respective domain

  8. Pitfalls in sharing derived content • Download Upload Round Trip • Video Encoding Complexity • Web Setup • Process Duplication • Scalability

  9. Direct Transfer • Easy Sharing • Reusable • Ubiquitous Gaps SeedMe.org • Download Upload • Video Encoding • Web Setup • Process Duplication • Scalability • Direct Access • Not All Members Have HPC Access • Direct Sharing • Security Implications On HPC

  10. Why not use existing tools?

  11. SeedMe Architecture Ingestion (Atomic or Recurring) • Instant Processing • (Text, Images) • Notification • Responsive Content Access • Batch Processing • (Videos)

  12. SeedMe Hardware Ingestion (Atomic or Recurring) • Instant Processing • (Text, Images) • Notification • Responsive Content Access • Batch Processing • (Videos) 20 gbe Web Cluster (2-8 nodes) : Drupal 20 gbe 20 gbe Phones Ingest Temp Storage (10TB) Mirrored Storage (50 TB) : ZFS Tablets Encode Cluster (16 nodes) : Apple Compressor + ffmpeg Desktops

  13. Compressor Encoding Benchmark

  14. SeedMe Collection Ticker* • Plots • Image Sequences* • Videos Access: Public, Group, Private Collaborators Meta Data * Recurring: periodic update

  15. SeedMe: Interaction Process Create New Collection Set Access Control (Public, Group, Private) Specify collaborators* and meta data Upload/Update content http/https, ftp, Globus Online Interactively on Web, Command Line or REST Services View Collection on Web

  16. SeedMe: Interaction Modality • Command Line Interface (using curl) • Web Interface (WYSIWYG) • RESTful API (integrate your tool chain) • JSON

  18. Application Scenarios • Monitor progress with text tickers and images • Encode and stream videos from image sequences • Share & collect visualization results • Use the collections for education and outreach Content accessible on most devices

  19. Work in progress How it Works Examples #1 & #2 Periodic update at simulation run time from a Magneto Hydrodynamics Simulation Courtesy of Mahidhar Tatineni and Homa Karimabadi, UCSD

  20. Future Work • Production SeedMe Service • Example Scripts& Documentation • Globus integration with SeedMe
