Scaling I/O Beyond 100,000 Cores using ADIOS

SESSION: Scaling I/O Beyond 100,000 Cores using ADIOS

EVENT TYPE: Tutorials

TIME: 1:30PM - 5:00PM

Presenter(s):Qing Liu, Norbert Podhorszki, Scott Klasky

ROOM:407

ABSTRACT:
As concurrency continues to increase on high-end machines, from both the number of cores and storage devices, we must look for a revolutionary way to treat I/O. As a matter of fact, one of the major roadblocks to exascale is how to write and read big datasets quickly and efficiently on high-end machines. On the other hand applications often want to process data in an efficient and flexible manner, in terms of data formats and operations performed (e.g., files, data streams). In this tutorial we will show how users can do that and get high performance with ADIOS on 100,000+ cores. Part I of this tutorial will introduce parallel I/O and the ADIOS framework to the audience. Specifically we will discus the concept of ADIOS I/O abstraction, the binary-packed file format, and I/O methods along with the benefits to applications. Since 1.4.1, ADIOS can operate on both files and data streams. Part II will include a session on how to write/read data, and how to use different I/O componentizations inside of ADIOS. Part III will show users how to take advantage of the ADIOS framework to do compression/indexing. Finally, we will discuss how to run in-situ visualization using VisIt/Paraview+ADIOS.
