OLCF staff delivered talks and tutorials to Lustre users covering the center’s on-going contributions to the effort to expand the parallel file system’s performance and flexibility.
ORNL's MDF recently reached out to the Oak Ridge Leadership Computing Facility’s (OLCF’s) Advanced Data and Workflow Group for assistance with 3-D visualization.
The OLCF will support a new service, Spark On-Demand, that enables users to instantiate Apache Spark to conduct in situ data analysis on OLCF compute resources.
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.
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.
The Joint Facilities User Forum on Data-Intensive Computing brought together users and HPC center staff to discuss approaches to handling data, best practices, and the future of data-driven scientific discovery.
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.
At the Oak Ridge Leadership Computing Facility (OLCF), users on the world’s most powerful supercomputer for open science, Titan, are routinely producing tens or hundreds of terabytes of data, and many predict their needs will multiply significantly in the next 5 years.
The OLCF recently relocated the center’s archive tape library to a centralized location with a more controlled environment, resulting in better overall availability and uptime for OLCF system users and better resiliency of the media.
