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.
DCP has helped OLCF staff move 350 terabytes of data so far on behalf of some users, while other users have independently used dcp to copy much more.
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 has introduced the next generation of data management with Atlas, a new center-wide file system that delivers increased capacity, greater performance, and a new directory structure for OLCF computational users.
With its hybrid architecture featuring traditional CPUs alongside GPUs, Titan represents a revolutionary paradigm in high-performance computing’s quest to reach the exascale with only marginal increases in power consumption for the world’s leading systems.
The OLCF is working with Mentor Graphics, a leading electronic design automation company, to bring accelerated computing to a broader audience.
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.
Two new computing resources are being installed at the OLCF to enhance the user experience and maximize project outputs.
