Podcast: The Exascale Data and Visualization project at LANL

In this episode of Let’s Talk Exascale, Scott Gibson discusses the ECP Data and Visualization project with Jim Ahrens from Los Alamos National Lab. Ahrens is principal investigator for the Data and Visualization project, which is responsible for the storage and visualization aspects of the ECP and for helping its researchers understand, store, and curate scientific data.

ADIOS 1.11 Middleware Moves I/O Framework from Research to Production

The Department of Energy’s Oak Ridge National Laboratory has announced the latest release of its Adaptable I/O System (ADIOS), a middleware that speeds up scientific simulations on parallel computing resources such as the laboratory’s Titan supercomputer by making input/output operations more efficient. “As we approach the exascale, there are many challenges for ADIOS and I/O in general,” said Scott Klasky, scientific data group leader in ORNL’s Computer Science and Mathematics Division. “We must reduce the amount of data being processed and program for new architectures. We also must make our I/O frameworks interoperable with one another, and version 1.11 is the first step in that direction.”
