Tiny Titan, the portable parallel computer designed for students and the general public by staff at the OLCF, is the subject of a new exhibit at the American Museum of Science and Energy (AMSE) in Oak Ridge, Tennessee.
The OLCF played a significant role in an ORNL event to share knowledge and discuss the future development of the parallel file system, Lustre.
OLCF staff have invested heavily in making sure users can access data quickly while also taking steps to keep data safe.
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.
