The Organization:
The National Center for Computational Sciences (NCCS) provides state-of-the-art computational and data science infrastructure for technical and scientific professionals to accelerate scientific discovery and engineering advances across a broad range of disciplines. As an important part of the broader High-Performance Computing (HPC) infrastructure, the division also hosts the Oak Ridge Leadership Computing Facility (OLCF), a Department of Energy Office of Science User Facility.
The Team:
The System Acceptance and User Environment Group is within the Operations Section of the NCCS and ensures the functionality, performance, and usability of new NCCS systems through activities such as test development, acceptance, software installation, documentation, and early user support for all NCCS pre-production systems.
