Berkeley Lab's Computational Research Division has an opening for a Postdoctoral Scholar to assist in the implementation and documentation of new high-performance computing (HPC) approaches to a variety machine learning challenges in the Physical Sciences. Over the course of the last five years, LBNL's Computing Research Division in collaboration with NERSC Data Analytics group and the Physics Division has developed a research program in data-driven pattern recognition algorithms for High Energy Physics (HEP) and Cosmology, targeting massively parallel and post-Moore architectures (including neuromorphic and quantum systems). Several promising research directions involve the development of distributed Geometric Deep Learning, algorithms based on distributed graph neural networks, as well as Generative Adversarial Networks.

What You Will Do:

• In the context of the ExaLearn Co-Design Center, will collaborate with LBNL physicists and computer scientists to develop innovative distributed pattern recognition algorithms for the next generation of HEP and Cosmology experiments and simulations on HPC systems.

• Develop workflows for distributed training and optimization of graph neural networks, GANs and regression algorithms as we push to Exascale.

• Investigate data and model parallelism approaches to train and run these on current HPC systems like ORNL Summit and NERSC 9.

• Troubleshoot and solve problems of moderate scope and monitor benchmarks and bottlenecks in current codes and document these efforts.

Additional Responsibilities as needed:

• May contribute to one or more existing research projects like CosmoFlow, CosmoGAN, and HEP.TrkX and HEP.QPR. The first three are dedicated the development of Machine Learning algorithms for Cosmology and HEP while the latter is focused on Quantum Computing Pattern Recognition algorithms for HEP experiments.

What is Required:

• Applicants need to have a Ph.D. in data sciences, computer science, software engineering, applied physics, physics, astronomy or related fields.

• Experience with modern data analytics and machine learning frameworks and libraries.

• Research experience in solving machine learning problems and demonstrated expertise in python for scientific computing.

• Background and experience in computational methods and scientific computing.

• Background in physics, engineering, or computer science.

• Excellent oral and written communication skills.

• Demonstrated ability to work effectively as part of a cross-disciplinary team.

Additional Desired Qualifications:

• Graph algorithms and libraries.

• 3-D convolutions.

• Pattern recognition.

• HEP computing, cosmology data analysis, cosmological simulation.

• Software performance evaluation and optimization.

• HPC systems.

• GPGPU programming.

• C++.
