Overview

1. Introduction
Lead times for the competitive design of automobiles and electric appliances are getting shorter and more
unforgiving each year. One way to reduce design lead time is to incorporate Computer Aided Engineering
(CAE). In particular, CAE related to electromagnetism often uses finite element analysis (FEA) [1] [2], and
reduction of analysis time is in great demand with users.
One good solution is to increase speed using parallel processing [3] [4]. Hardware configurations influence
software algorithms and affect parallel performance greatly, and hardware advances in recent years have been
remarkable. This means that software algorithms also need to advance to keep up. At JMAG, we implement
algorithms that are best suited for the latest hardware, and we produce some of the highest levels of parallel
performance in the industry [5] [6]. In particular, the shared memory type parallel (SMP) solver described below
is greatly improved in version 16.1, and the distributed memory type massively parallel (MPP) solver is vastly
improved in version 17.0.
In this white paper, we will explain why the new SMP and MPP parallel solvers are fast from the perspective of
the algorithms used. Additionally, we will attempt to clarify the influence of hardware system environments on
SMP and MPP. This document
