HPC Postdoctoral Researcher

Lawrence Berkeley National Lab’s (LBNL ) Applied Mathematics Department – Computational Research Division has an opening for an HPC Postdoctoral Researcher in Kinetic Methods to join the team.

 

In this exciting role, you will be part of Berkeley Lab’s (LBNL) Scalable Solvers Group in the Computing Research Division, developing high performance computing (HPC), structure preserving (SP), particle-in-cell (PIC), methods for kinetic models in PETSc (Portable, Extensible, Toolkit for Scientific computing). Kinetic models (up to 6D) are some of the most demanding tasks in Scientific Computing and new classes of Structure Preserving (SP) models and discretizations offer opportunities for unprecedented levels of accuracy and efficiency for use in modern large-scale, high-performance hardware. The postdoc will work with members of the PETSc team on developing and deploying these methods in the PETSc library, developing a global SP model for the Vlasov-Maxwell-Landau (VML) system for use in algorithmic research in fusion energy science as well as the closely related Vlasov-Poisson-Landau system for astrophysics applications.

 

What You Will Do:

• Work with the PETSc team on components of PETSc’s HPC SP VML project.
• Contribute to one or more of the ongoing projects within the group, including the development of software for high-performance computing systems and the development of new algorithms.

 

Additional Responsibilities as needed:

• Participate with the PETSc team to deploy open source software with state-of-the-art software engineering to the scientific computing community.
• Participate in interdisciplinary programs with plasma physicists in DOE’s office of fusion energy science (FES).

 

What is Required:

• Requires a Ph.D. in Computational Science, Software Engineering, Applied Physics, Physics, Astronomy, or related fields.
• HPC programming experience in, for example, PETSc, Kokkos/CUDA/HIP/SYCL, MPI.
• Ability to communicate effectively, and to contribute to a large software project.
• Demonstrated ability to prepare research results for publication and presentation at seminars and scientific meetings.

 

Desired Qualifications:

• Experience with PETSc.
• Experience with high-performance computing systems and software optimization with modern devices.
• Experience with plasma physics, finite element methods, mesh generation, solvers and/or particle methods.

 

Notes:

• This is a full-time 2 year, postdoctoral appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds and ongoing operational needs. You must have less than 3 years of paid postdoctoral experience. Salary for Postdoctoral positions depends on years of experience post-degree.
• This position is represented by a union for collective bargaining purposes.
• Salary will be predetermined based on postdoctoral step rates.
• This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
• Work may be performed on-site, or hybrid. You may occasionally travel to the University of Buffalo and Princeton. Work must be performed within the United States.
