System User Guides
Curated collections of knowledge base articles presented together for continuity, a system user guide is the definitive source for information on a particular OLCF system.
Titan User Guide
With a theoretical peak performance of more than 20 petaflops, Titan is the OLCF’s flagship supercomputer. This hybrid-architecture Cray XK7 system gives computational scientists unprecedented resolution for studying a whole range of natural phenomena.
Accelerated Computing User Guide
The flagship supercomputer at the OLCF, Titan, employs 18,688 NVIDIA Telsa K20X GPU accelerators. This guide is provided to aid researchers in the process of transforming traditional CPU code to accelerated code that is well-suited for execution on Titan.
EOS User Guide
Eos is a 744 node Cray XC30 cluster. The processor is the Intel® Xeon®E5-2670. The Eos compute partition contains 11,904 traditional processor cores, and 47.6 TB of memory. Suitable Eos uses include application porting, software generation and optimization, and small-scale jobs that support capability jobs on Titan.
RHEA User Guide
Rhea is a (512)-node commodity-type Linux cluster; its primary purpose is to provide a conduit for large-scale scientific discovery via pre/post processing and analysis of simulation data generated on larger, flagship OLCF systems.
Data Management User Guide
Data management has always been an important part of HPC. In this guide find information about the OLCF data policy, where and how to store your data, and how to transfer it.
