Berkeley Lab's Computational Research Division has an opening for a Postdoctoral Scholar. The Center for Computational Sciences and Engineering (CCSE) develops and applies advanced computational methodologies to solve large-scale scientific and engineering problems arising in DOE mission areas involving energy, environment, and industrial technology. One primary focus of CCSE researchers is on designing algorithms for multiscale, multiphysics problems described by nonlinear systems of partial differential equations, and in developing implementations of algorithms that target current and next-generation massively parallel computational architectures. CCSE researchers work collaboratively with application scientists to develop state-of-the-art solution methodologies in these fields.
This position is a research and software development position focusing on the continued development and application of MFIX-Exa, a new code for modeling multiphase flow using CFD-DEM with mesh refinement, based on the AMReX software framework. This position will be focused on two areas; the first is code and algorithm development along with performance testing and optimization. The second part of the position involves extension of the modeling capabilities of the MFIX-Exa code to explore new application areas. The software efforts are collaborative with the AMReX team so that MFIX-Exa makes full use of the AMReX capabilities and also contributes back to the core functionality. The new application areas should build on CCSE's existing strengths.
What You Will Do:
Participate in the continued development, testing and performance improvement of MFIX-Exa on current and next generation architectures.
Design and implement algorithmic and coding alternatives as needed to ensure high performance on hybrid CPU/GPU systems.
Develop and assess optimization strategies that mitigate potential computational and communication bottlenecks in MFIX-Exa.
Participate in exploring new application areas for the MFIX-Exa current and future capabilities.
Work independently and collaboratively in a multidisciplinary team environment including mathematicians, computer/computational scientists, and domain scientists.
What is Required:
Ph.D. in Applied Mathematics, Computer Science, or the Physical Sciences/Engineering within the last 3 years, with a strong research background in applied mathematics, computational methods, and scientific computing.
Demonstrated research experience in the modeling of fluids and/or of fluid-particle systems.
Demonstrated C++ and modern Fortran programming experience.
Experience with MPI and/or OpenMP.
Excellent verbal and written communication skills.
Ability to work productively independently and collaboratively as part of a diverse team.
Additional Desired Qualifications:
Experience with CFD-DEM a plus.
Experience with CUDA and/or other techniques for general purpose programming on GPUs.
Experience with visualization and analysis tools for fluid and/or particle flows.
Experience with python.
Experience with version control systems such as git.
The posting shall remain open until the position is filled.
This is a full time, 2 years, 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 paid postdoctoral experience. Salary for Postdoctoral positions depends on years of experience post-degree.
Full-time, M-F, exempt (monthly paid) from overtime pay.
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 will be primarily performed at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.

About Lawrence Berkeley National Laboratory
In the world of science, Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with excellence. Thirteen scientists associated with Berkeley Lab have won the Nobel Prize. Fifty-seven Lab scientists are members of the National Academy of Sciences (NAS), one of the highest honors for a scientist in the United States. Thirteen of our scientists have won the National Medal of Science, our nation's highest award for lifetime achievement in fields of scientific research. Eighteen of our engineers have been elected to the National Academy of Engineering, and three of our scientists have been elected into the Institute of Medicine. In addition, Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world. Berkeley Lab is a member of the national laboratory system supported by the U.S. Department of Energy through its Office of Science. It is managed by the University of California (UC) and is charged with conducting unclassified research across a wide range of scientific disciplines. Located on a 200-acre site in the hills above the UC Berkeley campus that offers spectacular... views of the San Francisco Bay, Berkeley Lab employs approximately 4,200 scientists, engineers, support staff and students. Its budget for 2011 is $735 million, with an additional $101 million in funding from the American Recovery and Reinvestment Act, for a total of $836 million. A recent study estimates the Laboratory's overall economic impact through direct, indirect and induced spending on the nine counties that make up the San Francisco Bay Area to be nearly $700 million annually. The Lab was also responsible for creating 5,600 jobs locally and 12,000 nationally. The overall economic impact on the national economy is estimated at $1.6 billion a year. Technologies developed at Berkeley Lab have generated billions of dollars in revenues, and thousands of jobs. Savings as a result of Berkeley Lab developments in lighting and windows, and other energy-efficient technologies, have also been in the billions of dollars. Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence's belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.
