The National Center for Supercomputing Applications' Blue Waters and Extreme Science and Engineering Discovery Environment (XSEDE) projects are hosting the sixth in a series of Extreme Scaling workshops.
Petascale systems provide computational science teams with effective, scalable, sustained petascale computing platforms. Our community expects these systems to provide sustained petascale performance on a broad range of science and engineering applications and algorithms, from applications that are compute-intensive to those that are data- and memory-intensive.
The workshop will address algorithmic and applications challenges and solutions in large-scale computing systems with limited memory and I/O bandwidth. The presentations and discussions are intended to assist the computational science and engineering community in making effective use of petascale through extreme-scale systems across the spectrum of local campus-scale to national systems.
The continued growth in the number of cores per chip and accelerator-based hybrid systems requires expanded application-driven requirements for new computational models and methods, improved parallel programming algorithms, software development for parallel and distributed systems, and application flexibility. Similarly, memory bandwidth limitations and increased challenges of data movement require significantly greater effort in fundamental approaches to application methods.
Achieving the full potential of these new systems with all their advanced technology components requires additional effort on the part of the science teams. Fortunately, these efforts are completely aligned with what science teams have to do in order to use almost any system over the next decade.
