In this paper we describe an experiment in which MANIFOLD is used to coordinate the interprocess communication in a parallelized proposition solver. MANIFOLD is very well suited for applications involving dynamic process creation and dynamically changing (ir)regular communication patterns among sets of independent concurrent cooperating processes. The idea in this case study is simple. The proposition solver consists of a fixed numbers of separate processing units which communicate with each other such that the output of one serves as the input for the other. Because one of the processing units performs a computation intensive job, we introduce a master/worker protocol to divide its computations. We show that this protocol implemented in MANIFOLD adds another hierarchic layer to the application but leaves the previous layers intact. This modularity of MANIFOLD offers the possibility to introduce concurrency step by step. We also verify the implementation of the proposition solver using a simple family of assertions and give some performance results.

The 15 th HIPS workshop, to be held as a full-day meeting at the IPDPS 2010 conference in Atlanta, focuses on high-level programming of multiprocessors, compute clusters, and massivelyparallel machines. Like previous workshops in the series, which was established in 1996, this event serves as a forum for researchers in the areas of parallel applications, language design, compilers, runtime systems, and programming tools.

The 25th HIPS workshop, a full-day meeting on May 18th at the IEEE IPDPS 2020 conference in New Orleans (now virtual), focuses on high-level programming of multiprocessors, compute clusters, and massivelyparallel machines. Like previous workshops in the series, which was established in 1996, this event serves as a forum for research in the areas of parallel applications, language design, compilers, runtime systems, and programming tools. It provides a timely forum for scientists and engineers to present the latest ideas and findings in these rapidly changing fields. In our call for papers, we especially encouraged innovative approaches in the areas of emerging programmingmodels for large-scale parallel systems and many-core architectures.

This paper focuses on the validation of a new all-speed Computational Fluid Dynamics (CFD) code called Loci-STREAM. This computational package is not just another CFD solver;rather, it integrates proven numerical methods and state-of-the-art physical models to compute all-speed flows using generalized grids in a novel rule-based programming framework called Loci which allows: (a) seamless integration of multidisciplinary physics in a unified manner, and (b) automatic handling of massivelyparallel computing. The objective is to be able to routinely simulate problems involving complex geometries requiring large unstructured grids with arbitrary polyhedral cells and complex multidisciplinary physics. As a first step towards achieving this objective, a wide range of model test cases are studied here, including incompressible laminar and turbulent flow cases, inviscid compressible flow cases, compressible turbulent flows with wall heat transfer as well as internal turbulent flows in 3D geometries and unsteady computations. Comparison of the code with experimental and prior benchmark numerical results is done to validate the robustness of the code for flows ranging from incompressible to supersonic regimes. A scalability analysis is performed as well to study the efficiency of parallelization.
