A Comparison of Parallel Workstation Sonar Beamforming Implementations
نویسنده
چکیده
We implement a prototype for a 20-GFLOP sonar beamformer with multiple frameworks for parallelism: MPI, Computational Process Networks, and a hybrid of the two. Computational Process Networks is a framework based on the formal Process Network model and Computation Graphs, implemented with lightweight POSIX threads. We benchmark these systems on a Sun Enterprise 4000. On eight UltraSPARC-II processors, we measure speedups of 6.5 for Computational Process Networks, 3.5 for MPI, and 2.9 for the hybrid.

Implementation of the direction of arrival estimation algorithms by means of GPU-parallel processing in the Kuda environment (Research Article)
Direction-of-arrival (DOA) estimation of audio signals is critical in different areas, including electronic war, sonar, etc. The beamforming methods like Minimum Variance Distortionless Response (MVDR), Delay-and-Sum (DAS), and subspace-based Multiple Signal Classification (MUSIC) are the most known DOA estimation techniques. The mentioned methods have high computational complexity. Hence using...
