Software Release: Tuned MPI Graph 500 Implementation with 2-D Data Distribution

Graph 500 uses a two-dimensional data distribution and several other techniques for scalable performance on large systems and graphs. "Big Data" and other unstructured, irregular applications have become increasingly important in the past few years, and high-performance computing is being applied to these problems. However, standard benchmarks used for supercomputers, particularly LINPACK, do not measure performance on these new types of applications.

Plenoptic Photography featured at Grunwald Gallery

Photographer Jeff Wolin and Professor Andrew Lumsdaine collaborated in a project to create images with plenoptic cameras, a new technology that captures the entire field of light surrounding an image instead of focused points of light captured by a traditional camera.  Plenoptic cameras allow users to refocus caputred images as well as take 3D pictures.

Harlan: New programming language accelerates GPU computing

It’s an interesting irony of computing that programs – and the programming languages in which they are written – are often much longer-lived than the computing platforms they run on. Computers are constantly evolving as hardware continues to advance, and one of the features of higher-level programming languages is to insulate programmers from those changes. There is a tension however.

IU awarded $1.1 million to Advance Supercomputer Programmability

Indiana University’s Center for Research in Extreme Scale Technologies (CREST) is the recipient of a three-year, $1.1 million grant from the US Department of Energy (DOE) to develop software that improves the speed and programmability of supercomputers. This funding is part of a $7.05 million grant for the XPRESS (eXascale PRogramming Environment and System Software) project, led by Sandia National Laboratories as part of the DOE Office of Science Advanced Scientific Computing Research X-Stack programme.

Andrew Lumsdaine, Nick Edmonds, and Jeremiah Willcock had a paper accepted to ICS 2013

ICS is the premier international forum for the presentation of research results in high-performance computing systems. ICS 2013 will be held at the University of Oregon, Eugene, Oregon, in the heart of the Willamette Valley.

CREST participates at SC12

CREST leaders, scientists, and students are playing an active role at SC12 held in Salt Lake City, Utah in November. Below is a list of CREST activities:
