- 9. 9 RESOURCES Paper: Parallelization of a Denoising Algorithm for Tonal Bioacoustic Signals using OpenACC Directives Jorge Castro, Advanced Computing Laboratory, Costa Rica National High Technology Center Esteban Meneses, School of Computing, Costa Rica Institute of Technology Automatic segmentation and classification methods for bioacoustic signals enable real- time monitoring, population estimation, as well as other important tasks for the conservation, management, and study of wildlife. These methods normally require a filter or a denoising strategy to enhance relevant information in the input signal and avoid false positive detections. This denoising stage is usually the performance bottleneck of such methods. This paper discusses parallelizing a denoising algorithm for tonal bioacoustic signals using mainly OpenACC directives. The implemented program was executed in both multicore and GPU architectures. The proposed parallelized algorithm achieves a higher speedup on GPU than CPU, leading to a 10.67 speedup compared to the original sequential algorithm in C++. READ NOW
- 10. 10 RESOURCES Blog: Optimizing an OpenACC Weather Simulation Kernel Alan Gray, NVIDIA This blog article describes recent work to optimize an OpenACC code provided by the Met Office in the United Kingdom. This relatively small computational section has been developed as part of preparations to move to the new LFRic Weather Simulation Model. LFRic will be developed using an automated system called PSyclone which itself is currently under development at The Hartree Centre to generate performance-portable parallel code, including OpenACC-augmented Fortran for execution on GPUs. The hand-tuning of the code described in this blog provides a “gold standard” for PSyclone, to ensure that it is developed in a way that permits good performance on the GPU architecture. READ NOW
