What You Will Do
The High Performance Computing (HPC) Division at Los Alamos National Laboratory provides scientific computing resources consisting of some of the largest HPC systems in the world. The Systems team within the HPC Design Group (HPC-DES) is responsible for defining the technical direction, evaluating, developing and deploying the tools and system software ultimately used in production support of LANL’s HPC resources. These HPC resources are some of the largest in the world and currently include a large (19K+ node) Cray system called Trinity as well as numerous large commodity cluster systems.
