The OLCF’s RAIT system allows incoming data to be striped across four tapes, but it also has an extra tape—called a parity tape—that can allow the data to be reconstructed in the event that a tape is damaged or lost.
In the spirit of saving energy, the OLCF brought in an engineering team to evaluate how existing supercomputers could be cooled more efficiently.
In preparation for Summit, computer scientists and support staff are leaning on two modest-but-mighty test systems to explore Summit’s cutting-edge architecture.
Staff at ORNL saw a need for more efficient systems testing; through a collaboration of groups at the OLCF, they were able to build a state-of-the-art test harness.
To make sure Summit is ready for researchers from day one, the OLCF Scientific Computing, Technology Integration, and High-Performance Computing Operations groups are collaborating on a test bed for staff and vendors to help the OLCF prepare for Summit.
Jack Wells, OLCF director of science, was recently invited to be the keynote speaker of an OpenACC workshop at the University of Houston.
At the Oak Ridge Leadership Computing Facility computer scientists Devesh Tiwari and Saurabh Gupta see laziness—a changed perception that reduces the frequency of application-level checkpoints—as increasingly important in recovering from computer failures on larger and faster machines.
In October, 2014, a working group at the US Department of Energy’s Oak Ridge National Laboratory received a significant event award for streamlining the process of writing, testing, reviewing, and deploying code.
From October 27 to 31, scientific computing teams from around the world gathered in Knoxville to participate in the OLCF’s inaugural Hackathon, an OpenACC event specifically aimed at scaling scientific applications to run on heterogeneous, high-performance computing systems such as Titan.
For many researchers, Titan is only part of the picture; managing and understanding data are quickly becoming as important as the simulations that create it.
