A broad set of data science and engineering questions may be organized as graphs, providing a powerful means for describing relational data. Although experts now routinely compute graph algorithms on huge, unstructured graphs using high performance c

Performance and energy are two major concerns for application development on heterogeneous platforms. It is challenging for application developers to fully exploit the performance/energy potential of heterogeneous platforms. One reason is the lack of

The performance of a large-scale, production-quality science and engineering application 'app' is often dominated by a small subset of the code. Even within that subset, computational and data access patterns are often repeated, so that an even small

This paper describes improvements in task scheduling for the Chapel parallel programming language provided in its default on-node tasking runtime, the Qthreads library. We describe a new scheduler distrib which builds on the approaches of two previou

The co-design of architectures and algorithms has been postulated as a strategy for achieving Exascale computing in this decade. Exascale design space exploration is prohibitively expensive, at least partially due to the size and complexity of scient

Multicore processors form the basis of most traditional high performance parallel processing architectures. Early experiences with these computers showed significant performance problems, both with regard to computation and inter-process communicatio

In 2005, Oak Ridge National Laboratory (ORNL) received delivery of a 5294 processor Cray XT3. The XT3 is Cray's third-generation massively parallel processing system. The ORNL system uses a single-processor node built around the AMD Opteron and uses
