NERSC’s mission is to accelerate scientific discovery at the U.S. Department of Energy (DOE) Office of Science through high performance computing and data analysis. NERSC supports the largest and most diverse research community of any supercomputing facility within the U.S., providing large-scale, state-of-the-art computing for unclassified research programs in alternative energy sources, environmental science, materials research, astrophysics and other science areas related to DOE’s science mission. Data-intensive computing has been of growing importance at NERSC. Considerably more data is transferred to NERSC than away from NERSC. Experimental facilities are being inundated with data due to advances in detectors, sensors and sequencers — in many cases these instruments are improving at a rate even faster than Moore’s law for semiconductors. Scientists are finding it increasingly difficult to analyze these large scientific data sets and, as a consequence, they are often transferring data to supercomputing centers like NERSC. Examples range from cosmology to particle physics to biology. Berkeley Lab is partnering with other institutions to create a Superfacility for Science through advanced networking, the development of new supercomputing technologies and advances in software and algorithms. The U.S. Department of Energy’s Energy Sciences Network (ESnet) is tying together experimental instruments, supercomputing facilities and research institutions at high speeds. Supercomputers at NERSC are increasingly being designed to support data workflows, including the following developments: - Use of nonvolatile memory as storage to accelerate IO - User defined images for customizing the run-time environment for any application - A customizable compute gateway to accelerate connections to remote experimental facilities - A data software stack that includes frameworks/libraries for AI, tools for managing workflows, moving data and visualization - Real-time queues for interactive use We have started planning for NERSC-10 and NERSC-11 which will be deployed in 2024 and 2028, respectively. Nearing the end of Moore’s Law, we are examining a number of alternative architectures. It is possible that these systems will be highly heterogenous and include an array of different workflow accelerators. In this presentation, I will discuss several pathfinding efforts currently underway.
