Oak Ridge National Laboratory is the US Department of Energy’s largest multi-program science and energy laboratory, with scientific and technical capabilities spanning the continuum from basic to applied research. Located in the city of Oak Ridge, ORNL is in the eastern part of Tennessee in the foothills of the Great Smoky Mountains.

The Technology Integration Group in the National Center for Computational Sciences Division and the Extreme Scale Systems Center at Oak Ridge National Laboratory invites applications for a Post-Master's appointment in computer science research.


The Group’s research and development efforts cover a broad spectrum of areas of computer science and engineering associated with high-performance parallel computing and interacts strongly with large-scale applications in several scientific and technical fields, as well with the Oak Ridge Leadership Computing Facility (OLCF, http://olcf.ornl.gov). More information on the Technology Integration Group may be found at, http://techint.nccs.gov/.

MS in Computer Science or related field is required.

The successful applicant will have demonstrated significant experience in:
• Programming in C and/or C++
• Multithreading using POSIX threads
• Network programming using TCP sockets
• Shell scripting

Oak Ridge National Lab is the Department of Energy’s largest science and energy laboratory with over 4,600 staff from more than 100 countries, 3,000 guest researchers, and a budget of approximately $1.4 billion. The Lab supports the Department of Energy’s mission by providing solutions to strengthen the nation’s leadership in key areas of science; increase the availability of clean, abundant energy; restore and protect the environment; and contribute to national security.

 

ORNL is home to Titan, a Cray XK7 system consisting of 18,688 AMD sixteen-core Opteron™ processors providing a peak performance of more than 3.3 petaflops (PF) and 600 terabytes (TB) of memory. A total of 512 service input/output (I/O) nodes provide access to the 10 petabytes (PB) “Spider” Lustre parallel file system at more than 240 gigabytes (GB/s). External login nodes (decoupled from the XK7 system) provide a powerful compilation and interactive environment using dual-socket, twelve-core AMD Opteron processors and 256 GB of memory.  Each of the 18,688 Titan compute nodes is paired with an NVIDIA Kepler graphics processing unit (GPU) designed to accelerate calculations. With a peak performance per Kepler accelerator of more than 1TF, the aggregate performance of Titan exceeds 20PF.
Titan is the Department of Energy’s most powerful open science computer system available to the international science community.

 

Researchers from industry, academia, and government use ORNL supercomputers and support systems for data analytics, visualization, and storage to illuminate phenomena that are often impossible to study in a laboratory, such as climate change, galaxy formation, or fusion in a reactor not yet built. Simulations compress design cycles and lower costs for vehicle engines, airplane wings, and power plants, as virtual prototypes can be tested before their physical construction. In fields from disaster relief to the electric grid, simulations provide real-time situational awareness to inform decisions. Modeling and simulation speed insights into electrochemical energy storage, solar photovoltaic conversion, and the nuclear fuel cycle. Simulations led to the invention of a novel supercapacitor, forced rewriting of astrophysics textbooks when it was revealed how pulsars get their spins, and exposed the molecular mechanism of Parkinson’s disease. DOE supercomputers have helped the Federal Bureau of Investigation find child pornographers and the Department of Defense assess terrorist threats. An ORNL computing infrastructure to help the Centers for Medicare and Medicaid Services combat fraud is underway. An important focus lab-wide is managing the tsunamis of data generated by supercomputers and at facilities like ORNL’s Spallation Neutron Source.
