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.
A new data quality assurance tool developed by the Technology Integration Group at the OLCF will help protect that data by validating the integrity of the High Performance Storage System (HPSS) archive.
When the Oak Ridge Leadership Computing Facility replaced its Jaguar supercomputer with Titan, not only did it expand its computing speed tenfold, it also saved on the electric bill.
Titan’s stability translates into an improved experience for Titan users. Fewer unscheduled outages and node failures reduce job interruptions, allowing jobs to run to completion with fewer restarts.
Oak Ridge Leadership Computing Facility staff members Robert French, Adam Simpson, Suzanne Parete-Koon, and Anthony DiGirolamo developed Tiny Titan, which is substantially tinier than Titan in size and cost.
The OLCF-organized series “Extreme Scale Supercomputing with the Titan Supercomputer,” chaired by Jack Wells, director of science, brought together Titan users in 24 conference sessions amounting to 540 minutes.
