BOLT: Optimizing OpenMP Parallel Regions with User-Level Threads
International Conference on Parallel Architectures and Compilation Techniques, 2019OpenMP is widely used by a number of applications, computational libraries, and runtime systems. As a result, multiple levels of the software stack use OpenMP independently of one another, often leading to nested parallel regions.

In this paper we present our experiences parallelizing the C++ programs DROPS and FIRE with OpenMP. Though the OpenMP specification includes C++, several shortcomings and missing features can be noticed in both the current OpenMP compilers and the specification.

Calculating Response-Time Bounds for OpenMP Task Systems with Conditional Branches
IEEE Real Time Technology and Applications Symposium, 2019Existing DAG-based task models in real-time scheduling research assume well-nested structures recursively composed by single-source-single-sink parallel and conditional components.

We propose an OpenMP programming environment for fine-grained approximate computing on multi-core cluster architecture with shared and accuracy-reconfigurable floating-point units (FPUs). This shared-FPUs cluster dynamically characterize FP pipeline vulnerability (FPV) and expose it as metadata to a software scheduler for reducing the cost of error ...

User Co-scheduling for MPI+OpenMP Applications Using OpenMP Semantics
2017The evolution of parallel architectures towards machines with many-core processors and high node-level concurrency is putting an end to the pure-MPI programming model. Simulations codes must expose multiple levels of parallelisms inside and between nodes, combining different programming models (e.g., MPI+X), to productively use current and future ...
