ORCA Team at SC11 PDF Print E-mail

At SC11 conference the RENCI/Duke ORCA team demonstrated the capabilities of the ORCA provisioning software to create slices of computational and network substrate spanning the entire country. The slices were used to compute molecular properties of candidate solar fuel catalyst materials for a related DOE-funded project. The computation involved a number of serial steps computed on dynamically provisioned cloud resources in NC, connected via BEN, to the DOE Hopper super computer, on which 3000 cores were used to complete the last step. Pegasus workflow management system orchestrated the computation steps within the slice. 

To create the slices ORCA concatenated dynamic circuits acquired from National Lambda Rail (via Sherpa), ESNet (via OSCARS) and BEN into a single Layer 2 high-bandwidth circuit. It also dynamically provisioned cloud resources at UNC, RENCI and Duke to enable the execution of the workflow.

CHAPEL HILL, February 18, 2011–With funds from the GENI Project Office (GPO) distributed through Stanford University, RENCI and its Triangle area university partners recently received five OpenFlow-enabled network switches valued at $3,000 per unit.

The donation is meant to help campuses create or expand their OpenFlow networks for both research and production uses.

The switches will be deployed on campuses and in the Points of Presence of RENCI’s Breakable Experimental Network (BEN), a regional optical network test bed used for experiments with disruptive networking technologies. 

The OpenFlow switches will be connected to BEN and will enable new cutting-edge networking research and educational opportunities at UNC-Chapel Hill, North Carolina State University and Duke University. They will be installed over the next few weeks at the BEN PoPs at RENCI and UNC Chapeil Hill and in laboratories and facilities of the computer science departments at Duke, UNC Chapel Hill and NC State.

 Visit RENCI  website for further details.

Cypress, CA, April 12, 2010 –  GENI’s Cluster D projects are using the dynamic  VLAN provisioning tool, Sherpa, developed by National LambdaRail (NLR), over NLR’s Layer 2 switched Ethernet service, FrameNet, to interconnect all participating testbed networks.  As a result, resources managed by Duke University in Durham, NC, the Renaissance Computing Institute (RENCI) in Chapel Hill, NC, the University of Massachusetts at Amherst and soon Ohio State University in Columbus are now linked with each other and with the Starlight international exchange facility at Northwestern University in Chicago, effectively functioning as a single network resource for the GENI community.

See the full press release from NLR for more information.
