Abstract: This paper studies the efficiency of the General Purpose
Computation on Graphics Processing Units (GPGPU) technique for the
implementation of a parallel Particle Swarm Optimization (PSO) algorithm
applied for the optimization of electromagnetic field devices. Several
sequential PSO algorithms are compared in order to find the optimal
configuration of an electromagnetic device, the TEAM22 benchmark
electromagnetic problem. The best PSO algorithm is parallelized by using a
GPGPU technique using various configurations for kernels and threads per
block. Details of the parallel implementations are explained. The sequential
and parallel implementations are compared using as criteria the speed up and
the solution quality. The most efficient approach turned to be the one with
one thread per block, which was up to 4 times faster than a sequential
implementation running on hardware architectures with processors much more
advanced than the core processors of the GPU.
