GCN : December 2013
GCN DECEMBER 2013 • GCN.COM 11 When researchers at the Energy Depart- ment's Oak Ridge National Laboratory threw the last switches on the Titan supercomputer in October 2012, they activated a machine that could calculate at 20 peta ops --- 20,000 trillion calcula- tions each second. But even then, sci- entists were already tweaking the design and bringing new ideas to the table to help build even faster computers in the near future. One recent improvement, according to the Oak Ridge Leadership Council, in- volves installing smaller supercomputers whose sole purpose is to sift through the massive stream of data being generated by Titan. The rst is called Eos and comprises a 744-node Cray XC30 cluster with a total of 47.6 TB of memory. For the rest of this year, it will support the Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program. IN- CITE awards time on supercomputers to researchers with large-scale, computa- tionally intensive projects that address "grand challenges" in science. To help with compatibility, Eos uses many of the same debuggers, pro ling codes and software packages that are used on Titan. "Eos is the newest generation of Cray architecture," said Suzanne Parete-Koon of the Oak Ridge Leadership Computing Facility User Assistance and Outreach group in the Oak Ridge internal newslet- ter. "The machine initially will be used as an extra computing resource to help INCITE projects reach their goals." In addition to Eos, a new cluster of 196 Dell PowerEdge C600 nodes is coming online. That grouping of comput- ers is called the Rhea cluster and will be dedicated to the post-processing analysis of visual data generated by Titan. Rhea is loaded up with programs such as ParaView and iPython designed to help process visual information. • Oak Ridge adds supercomputers to handle Titan's data BY JOHN BREEDEN II TOPICS INCLUDE: ONLINE REPORT SPONSORED BY XEROX Special Report ROADMAPTO A CONTACT CENTER OF EXCELLENCE PERFORMANCE HINGES ON CUSTOMER SERVICE CULTURE CONTACT CENTERS: GET READY FOR SOCIAL MEDIA THE MOBILE CHANNEL: THE TIME IS NOW CONTACT CENTERS SEEK RIGHT FIT FOR THE CLOUD TO IMPROVE PERFORMANCE, YOU NEED TO MEASURE IT GCN.COM/2013CONTACTCENTERS TO LEARN MORE, VISIT: OAK RIDGE NATIONAL LABORATORY The 20 petaflop Titan generates a lot of data, so smaller supercomputers will help sort it out.
