Why Cray is Backing Lustre and OpenSFS

Cory Spitz, Manager, Storage and Data Management R&D File Systems at Cray

“At Cray, we are a big user and investor in Lustre. Because Lustre is such a great fit for HPC, we deploy it with almost all of our systems. We even sell and deliver Lustre storage independent of Cray compute systems. But Lustre is not (yet) the perfect solution for distributed and parallel-I/O, so Cray invests a lot of time and resources into improving, testing, and honing it. We collaborate with the open-source Lustre community on those enhancements and development. In fact, Cray is a leader in the Lustre community through our involvement in OpenSFS.”

Video: Preparing Your Application for Advanced Manycore Architectures

Katie Antypas,
Services Department Head, National Energy Research Scientific Computing Center, Lawrence Berkeley National Laboratory

“Confronting power limitations and the high cost of data movement, new supercomputing architectures within the DOE are requiring users make changes to application codes to achieve high performance. More specifically, users will need to exploit greater on-node parallelism and longer vector units, and restructure code to take advantage of memory locality. In this presentation you will learn about coming architectural trends and what you can do now to start preparing your application.”

Bill Gropp on Engineering for Performance in HPC

Bill Gropp

Achieving good performance on any system requires balancing many competing factors. More than just minimizing communication (or floating point or memory motion), for high end systems the goal is to achieve the lowest cost solution. And while cost is typically considered in terms of time to solution, other metrics, including total energy consumed, are likely to be important in the future. Making effective use of the next generations of extreme scale systems requires rethinking the algorithms, the programming models, and the development process. This talk will discuss these challenges and argue that performance modeling, combined with a more dynamic and adaptive style of programming, will be necessary for extreme scale systems.

Supercomputing 101: A History of Platform Evolution and Future Trends

Rob Neely

This talk gives a history of the various eras of High Performance Computing as defined by the dominant platforms, starting with mainframes and continuing through vector architectures, massively parallel architectures, and the current emerging trends that will define the upcoming exascale era.

Supercomputing 102: The Toolbox of a Successful Computational Scientist

Judith Hill

“Successful computational scientists are experts in both a scientific field, such as chemistry, physics, or astrophysics, knowledgeable about both mathematical representations and algorithmic implementations, and also specialize in developing and optimizing scientific application codes to run on computers, both large and small. A truly successful computational science investigation requires the “three A’s”: a compelling Application, the appropriate Algorithm, and the underlying Architecture.”
