Chapter 3
The Way the HPC Works in CFD
Abstract
Rapid growth in the capability of single-processor computers has slowed in recent years. It is now evident that further increases in speed require multiple processors. The advantage of high-performance computing over classical vector supercomputers is scalability. The computers also use standard chips and are therefore cheaper to produce. Commercially available parallel computers may have thousands of processors, terabytes of memory, and computing power able to perform one quadrillion floating point operations per second. However, it is a fact that computational fluid dynamic (CFD) algorithms designed for traditional serial machines may not run efficiently on parallel computers. This chapter focuses ...
