Why do kernels not give a good evaluation of performance?
Check out CD4.7:2 on the CD – on my iBook the directory for the CD Sections is at file:///Volumes/COD3E/Content/COD3e/CDSections/ and the PDF file you want is file:///Volumes/COD3E/Content/COD3e/CDSections/CD4.7.pdf but you’ll need to adjust these two URNs if you use a PC ;-). Here’s the relevant text from the PDF document: About the same time Whetstone was developed, the concept of kernel benchmarks gained popularity. Kernels are small, time-intensive pieces from real programs that are extracted and then used as benchmarks. This approach was developed primarily for benchmarking high-end computers, especially supercomputers. Livermore Loops and Linpack are the best-known examples. The Livermore Loops consist of a series of 21 small loop fragments. Linpack consists of a portion of a linear algebra subroutine package. Kernels are best used to isolate the performance of individual features of a computer and to explain the reasons for differences in the performance of real programs. Becaus
