Job Description

We have an opening for a Postdoctoral Researcher to perform research related to the GPU offloading software stack used in High Performance Computing (HPC). You will work collaboratively with LLNL researchers and develop new methodologies to execute, optimize, and interact with scientific applications targeting state-of-the-art heterogeneous many-core HPC systems. This position is in the Center for Applied Scientific Computing (CASC) Division within the Computing Directorate.

You will 

• Research, design and implement compiler-based tooling with the goal to improve GPU offloading performance, productivity, and portability.
• Research, design and develop mechanisms to identify and eliminate development, maintenance, and performance issues in application codes or in HPC programming models and runtime libraries.
• Research, design and implement scalable solutions to accumulate and distribute knowledge related to HPC computing, GPU offloading, and scientific application deployment.
• Provide support to allow HPC codes to effectively use the developed tools and techniques.
• Explore novel schemes to achieve automation in the above areas, e.g., via tooling and ML.
• Document research by publishing papers in peer-reviewed media and presenting papers within the DOE community and at conferences.
• Contribute to group grant proposals, including proposal presentations and preparation of proposals that will provide future research opportunities in the field, and participate in the establishment of future research directions.
• Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally to define and carry out the research.
• Perform other duties as assigned.

Qualifications

•  Recent PhD in Computer Science or a related field.
• Experience with parallel computing environments.
• Experience developing scientific applications in C/C++ in a Unix/Linux environment.
• Proficient verbal and written communication skills necessary to interact with interdisciplinary audiences in a clear and concise manner
• Demonstrated research productivity, as evidenced by authoring technical reports, peer reviewed publications, and delivering scientific presentations.
• Demonstrated ability to independently define, execute, and evaluate new research concepts related to compiler optimizations or HPC programming models such as OpenMP or RAJA

Qualifications We Desire

• Experience in compiler or programming model runtime development, preferably in the LLVM/OpenMP compilation/runtime framework.
• Experience in parallel programming, preferably in widely used parallel programing models, such as OpenMP, CUDA, HIP and/or MPI.
• Knowledge of Machine Learning algorithms, libraries and frameworks.
