Users to Test DataWarp Burst Buffer on Cori Supercomputer

Print Friendly, PDF & Email

coriNERSC reports that it has selected a number of HPC research projects to participate in the center’s new Burst Buffer Early User Program. For the first time, users will be able to test and run their codes using the new Burst Buffer feature on the center’s newest supercomputer, Cori.

“Burst Buffers have the potential to transform science on supercomputers: removing I/O bottlenecks, enabling new workflows and bringing together data analysis and simulations,” said Wahid Bhimji, a data architect at NERSC who is co-leading the Cori Early User Programs. “However, this is a brand new technology, offering a new way of working and bringing challenges from software to scheduling. So it is really important and exciting to be able to shape the use of this technology in collaboration with these important science projects.”

Cori Phase 1, recently installed in the new Computational Research and Theory building at Berkeley Lab, is a Cray XC system based on the Haswell multi-core processor. It includes a number of new features designed to support data-intensive science, including the Burst Buffer. Based on the Cray DataWarp I/O accelerator, the Burst Buffer is designed to enhance I/O performance and features a layer of non-volatile storage that sits between a processors’ memory and the parallel file system.

NERSC’s Burst Buffer Early User Program is one of several programs NERSC has rolled out this year to help users get up and running on Cori as soon as possible and tune the system to meet science needs. Proposals were solicited beginning in early August; selection criteria included scientific merit, computational challenges and broad use of Burst Buffer data features, such as I/O improvements, checkpointing, workflow improvements, data staging and visualization. The selected projects reflect the range of the six program offices in the DOE Office of Science and the breadth of scientific computing the center supports.

“We’re very happy with the response to the Burst Buffer Early User Program call,” said Deborah Bard, a data architect at NERSC who is also co-leading the Cori Early User Programs. “In fact, we decided to support more applications than we’d originally anticipated.” Some applications already had Laboratory Directed Research and Development funding at Berkeley Lab and existing support from NERSC staff. Others will be given earlier access to the Burst Buffer to enable their projects, though without dedicated NERSC support.
