Cheers for Magellan


We were glad to see DOE’s Magellan project getting some well-deserved recognition by the HPCwire Readers’ and Editors’ Choice Award at SC10 in New Orleans. Magellan investigates how cloud computing can help DOE researchers to manage the massive (and increasing) amount of data they generate in scientific collaborations. Magellan is a joint research project at NERSC at Berkeley Lab in California and Argonne Leadership Computing Facility in Illinois.

This award represents teamwork on several fronts. For example, earlier this year, ESnet’s engineering chops were tested when the Joint Genome Institute, one of Magellan’s first users, urgently needed increased computing resources at short notice.

Within a nailbiting span of several hours, technical staff at both centers collaborated with ESnet engineers to establish a dedicated 9 Gbps virtual circuit between JGI and NERSC’s Magellan system over ESnet’s Science Data Network (SDN). Using the ESnet-developed On-Demand Secure Circuits and Advance Reservation System (OSCARS), the virtual circuit was set up within an hour after the last details were finalized.

NERSC raided its closet spares for enough networking components to construct a JGI@NERSC local area network and migrated a block of Magellan cores over to JGI control.  This allowed NERSC and JGI staff to spend the next 24 hours configuring hundreds of processor cores on the Magellan system to mimic the computing environment of JGI’s local compute clusters.

With computing resources becoming more distributed, complex networking challenges will occur more frequently. We are constantly solving high-stakes networking problems in our job connecting DOE scientists with their data. But thanks to OSCARS, we now have the ability to expand virtual networks on demand. And OSCARS is just getting better as more people in the community refine its capabilities.

The folks at JGI claim they didn’t feel a thing. They were able to continue workflow and no data was lost in the transition.

Which makes us very encouraged about the prospects for Magellan, and cloud computing in general. Everybody is hoping that putting data out there in the cloud will expand capacity.  At ESnet, we just want to make the ride as seamless and secure as possible.

Kudos to Magellan. We’re glad to back you up, whatever the weather.
