  1. HPC Profile WG Marty Humphrey, co-chair Department of Computer Science University of Virginia Charlottesville, VA

  2. HPC Profile WG Status • HPC Basic Profile uploaded on Friday (v0.3) • New version already uploaded today (editor fixes) • BES draft uploaded on Wed (v29) • Changes since SC • Security section added to HPC Basic Profile (incl. X509) • Modifications to enhance interoperability • Tooling issues, refactoring, etc.

  3. Schedule • 2:00 – 2:45: Overview of the HPC Basic Profile (Glenn Wasson) • 2:45 – 3:00: “Attribute Matching” Extension (Chris Smith) • 3:00 – 3:30: General Discussion • What to do next

  4. “Activity Credential” Extension • Aka “Delegation” Extension • Scope/Intent: • “An ‘Activity Credential’ is not used for authentication to the HPC Basic Profile-compliant Web service; rather, such a credential is used for subsequent authentication e.g., to a data server or database, another HPC Basic Profile-compliant Web service, a credential-granting service, or an attribute service.” • “Multiple of the “Common Cases” of [HPC-U] can require the ability to securely transmit an Activity Credential: 3.4 (“Types of Data Access”); 3.6 (“Multiple Organization Use Cases”); 3.12 (“Cycle Scavenging”).”

  5. Use Cases of “Activity Credential” 1. Windows CCS: username/password to create a job 2. MyProxy

  6. Approach • “Such credentials are intended to be used by the activity described in the CreateActivity message JSDL. Consequently, this specification requires that the credentials also be conveyed within the CreateActivity message as a sibling element to the JSDL.”

  7. Next Steps • Additional use-cases? • Read the spec • Implement the spec • Improve the spec
