Parallel hardware and software implementations for electromagnetic computations
Cataloged from PDF version of article.Multilevel fast multipole algorithm (MLFMA) is an accurate frequencydomain
electromagnetics solver that reduces the computational complexity and
memory requirement significantly. Despite the advantages of the MLFMA, the
maximum size of an electromagnetic problem that can be solved on a single processor
computer is still limited by the hardware resources of the system, i.e.,
memory and processor speed. In order to go beyond the hardware limitations
of single processor systems, parallelization of the MLFMA, which is not a trivial
task, is suggested. This process requires the parallel implementations of both
hardware and software. For this purpose, we constructed our own parallel computer
clusters and parallelized our MLFMA program by using message-passing
paradigm to solve electromagnetics problems. In order to balance the work load
and memory requirement over the processors of multiprocessors systems, efficient
load balancing techniques and algorithms are included in this parallel code. As a
result, we can solve large-scale electromagnetics problems accurately and rapidly
with parallel MLFMA solver on parallel clusters.Bozbulut, Ali RızaM.S
