The new challenges presented by exascale system architectures have resulted in difficulty
achieving the desired scalability using traditional distributed-memory runtimes …

Task-based programming models for shared memory—such as Cilk Plus and OpenMP 3—
are well established and documented. However, with the increase in parallel, many-core …

Taskflow aims to streamline the building of parallel and heterogeneous applications using a
lightweight task graph-based approach. Taskflow introduces an expressive task graph …

Abstract The Young/Daly formula provides an approximation of the optimal checkpointing
period for a parallel application executing on a supercomputing platform. It was originally …

CG-Kit is a new Code Generation tool-Kit that we have developed as a part of the solution
for portability and maintainability for multiphysics computing applications. The development …

In this paper we introduce Cpp-Taskflow, a new C++ tasking library to help developers
quickly write parallel programs using task dependency graphs. Cpp-Taskflow leverages the …

We extend the capability of space-time geostatistical modeling using algebraic
approximations, illustrating application-expected accuracy worthy of double precision from …

Successfully exploiting distributed collections of heterogeneous many-cores architectures
with complex memory hierarchy through a portable programming model is a challenge for …

The 2018 Basic Research Needs Workshop on Extreme Heterogeneity identified five Priority
Research Directions for realizing the capabilities needed to address the challenges posed …

We present Task Bench, a parameterized benchmark designed to explore the performance
of distributed programming systems under a variety of application scenarios. Task Bench …
