DescriptionThe long-awaited Burst Buffer technology is now being deployed on major supercomputing systems. In this tutorial, we will introduce the Burst Buffers deployed at the two latest supercomputers at NERSC (Cori) and KAUST (Shaheen II) based on the Cray DataWarp, and discuss in detail our experience with Burst Buffers from both a system and a user’s perspective. Both KAUST and NERSC have been supporting BB projects for more than a year, and have developed a wealth of experience using these resources efficiently. For this tutorial, we combine the knowledge and experience of staff from both sites to provide attendees with an effective understanding of how to optimally use BB technology. We focus on optimizing massively parallel I/O for SSDs, a relatively new problem compared to well-established optimizations for parallel I/O to disk-based file systems. The tutorial will conclude with a live demonstration of a complex workflow executed on the Cray DataWarp, including simulation, analysis and visualization. We will also include user applications as case studies; we solicit user applications using this form: https://goo.gl/M3dUv9.
