Berkeley Lab is seeking a Computer Systems Engineer to devise performance enhancements to libraries that support the Global Address Space programming in a production environment design test procedures to assess performance and implement modifications that affect those changes, and implement low level communication network library support for heterogeneous systems that include GPUs.
The Computer Systems Engineer will:
Analyze the communication performance and inter-node scalability characteristics of the UPC++ and GASNet-EX libraries on supercomputers built from thousands of GPUs or manycore processors.
Develop new optimizations and algorithms to mitigate on-node or inter-node data movement bottlenecks in these libraries to enable faster on-node and off node communication performance.
Participate in a multidisciplinary team involving computer scientists, mathematicians, and domain scientists with the purpose of developing and deploying these libraries for the solution of scientific and engineering problems.
Document work and results in the form of technical reports, journal papers and conference proceedings.
Publish work and results at scientific meetings.
Bachelor's degree in computer science, computational science, or a related field with a minimum 5 years related experience; or Master's degree with a minimum of 3 years related experience, or equivalent work experience.
Experience implementing high quality software.
Experience in performance analysis and performance optimization of distributed and threaded applications.
High-performance parallel programming with C++.
Parallel programming in MPI, CUDA or a PGAS model
Performance analysis and performance optimization of distributed and threaded applications.
Proven consensus builder in a highly collaborative environment.
Excellent written and verbal communication skills.
This is a full time career appointment.
Full-time, M-F, exempt (monthly paid) from overtime pay.
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.
Berkeley Lab (LBNL) addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the U.S. Department of Energy's Office of Science.

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.
