- 7. 7 RESOURCES Poster: Towards OmpSs-2 and OpenACC Interoperation Orestis Korakitis, Simon Garcia De Gonzalo, Nicolas Guidotti, João Pedro Barreto, José C. Monteiro, and Antonio J. Peña The increasing demand in HPC to utilize accelerators has motivated the development of pragma-based directives to target these devices. OmpSs-2 and OpenACC are both directive-based solutions that allow application programmers to utilize accelerators. The two leverage distinct types of parallelism: task parallelism and data parallelism, respectively. Non-trivial scientific applications can benefit from both types of available parallelism. However, the combination of pragma-based models is difficult to coordinate, as both assume full control and are unaware of each other at runtime. We propose an interoperation mechanism to enable novel composability across pragma- based programming models. We study and propose a clear separation of duties and implement our approach by augmenting the OmpSs-2 programming model, compiler and runtime to support OmpSs-2 + OpenACC programming. READ POSTER
- 8. 8 RESOURCES Paper: Seismic Modeling and Migration with Random Boundaries on the NEC SX-Aurora TSUBASA Carlos H. S. Barbosa and Alvaro L. G. A. Coutinho Seismic imaging is a computationally demanding and data-intensive activity in the oil and gas industry. Reverse Time Migration (RTM) used in seismic applications needs to store the forward-propagated wavefield (or source wavefield) on disk. Aiming to mitigate the storage demand, we develop an RTM that implements the source wavefield reconstruction by introducing a new wave equation to the problem. We adjust the initial and boundary conditions to take advantage of the properties of random boundary conditions (RBC). The RBC does not suppress unwanted waves coming from the artificial boundary enabling the full wavefield recovery. Besides, it explores low correlations with non-coherent signals due to the random velocities in the boundary. We also develop compiler-guided implementations on a vector processor for seismic modeling and RTM, essential for Least-square Migration, Full Waveform Inversion, and Uncertainty Quantification applications. We test the seismic modeling and RTM on the 2- D Marmousi benchmark and 3-D HPC4E Seismic Test Suite. The numerical experiments show that the RTM which implements the wavefield reconstruction presents the best results in terms of execution time and hard disk demand. Lastly, the vector processor implementation is the one that requires fewer code modifications compared to the optimized baseline versions of the seismic modeling and RTM and GPU implementations, particularly for large 3D grids.

- 9. 9 RESOURCES Paper: Parallel OpenMP and OpenACC Mixing Layer Simulation Hígor Uélinton Da Silva, Claudio Schepke, Natiele Lucca, César Flaubiano Da Cruz Cristaldo, and Dalmo Paim De Oliveira It is estimated that up to 25% of the grain crop ends up being lost in the post- harvest. The correct drying of the beans is one of the measures to contain this loss. As the grain mass is a set of solid and empty spaces, its drying could be considered a problem of the coupled open-porous medium. In this paper, a mathematical and computer simulation model was proposed, which describes the convection in a free flow with a porous obstacle applied to the drying of the grain. A computational fluid dynamics scheme was implemented in FORTRAN using Finite Volume to simulate and compute the numerical solutions. The code is parallel implemented using OpenMP and OpenACC programming interfaces. As a result, there was a significant reduction in processing time in both cases. The total simulation time was eight times less for a multicore architecture (16 physical cores) and 17.3 times using a single GPU (Quadro M5000). READ PAPER
