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.
The PanDA collaboration holds potential benefits for OLCF as well as for ATLAS.
The Oak Ridge Leadership Computing’s Sudharshan Vazhkudai, working with colleagues at ORNL, North Carolina State University (NCSU) and Qatar Computing Research Institute (QCRI), has taken a step toward solving a key storage bottleneck.
When the Oak Ridge Leadership Computing Facility upgraded its Jaguar supercomputer to the Cray XK7 CPU/GPU hybrid system known as Titan, the center knew that upgrades to its data analysis and visualization resources were necessary to complement Titan’s more than 20 petaflops of computing power.
By adding a graphics processing unit (GPU) accelerator to the 16-core central processing unit (CPU) on each node, the OLCF substantially increased Titan’s computing capability, enabling INCITE researchers to reach unprecedented science achievements.
