The Scientific Computing Group (SciComp) works in partnership with users to help them obtain optimal results from the OLCF’s computational resources and systems. The SciComp group is composed of computational scientists representing a wide spectrum of domain sciences, including astrophysics, biophysics, chemistry, climate science, combustion, computational fluid dynamics, computer science, mathematics, and numerical analysis. Each research team using OLCF systems for a project in the INCITE user program is assigned a SciComp liaison who is familiar with the field of research. SciComp liaisons actively participate in the research, help design and optimize code for the users’ applications, streamline the computational workflow, solve computer issues that arise, and serve as the point of contact for expert help from data workflow and visualization specialists to assist in capturing data from the computational campaign in images and helping users analyze it.
