 A Language-Independent Set of Benchmarks for Parallel Processors
The Whetstone benchmark [2], for example, is speciÞcally designed to defeat attempts to vectorize, parallelize, or pipeline the code.
Even the Whetstone benchmark was originally intended as a weighted mean of several operations, with different sets of weights for different application mixes; yet the only numbers ever used are the default weights suggested by Curnow and Wichmann [2].
Benchmarks are often criticized as being too short to represent very large application programs, and this is particulary valid if one is measuring a machine with a program cache.

 Linux Benchmarking - Concepts
The original Whetstone benchmark was designed in the 60's by Brian Wichmann at the National Physical Laboratory, in England, as a test for an ALGOL 60 compiler for a hypothetical machine.
The version of the Whetstone benchmark that we are going to use for this example was slightly modified by Al Aburto and can be downloaded from his excellent FTP site dedicated to benchmarks.
Whetstone is not a Linux specific test, it's not even an OS specific test, but it certainly is a good test for the FPU in your Linux box, and also gives an indication of compiler efficiency for specific kinds of applications that involve FP calculations.

Benchmarks are frequently used to ensure the minimum level of performance in a procurement specification.
Benchmarks are often used to measure general things like graphics, I/O, compute (integer and floating point), etc., performance, but most measure more specific tasks like rendering polygons, reading and writing files, or performing operations on matrixes.

Benchmarks have been created to serve as standard codes that can be tried on different machines for comparison purposes.
The Whetstone benchmark is a collection of codes originally written in Algol 60 that test floating point math library performance.
Unfortunately, Whetstone has been recoded in other languages over the years, in both single and double precision, and "improved" from time to time (sometimes in ways that favored particular machines) so that it is almost impossible to compare one Whetstone rating to another.

 PERFORMANCE of VARIOUS COMPUTERS in COMPUTATIONAL CHEMISTRY
Benchmark results from both machine are included in this report, together with those from the 16-way Regatta HPC node (in which one of the dual core CPUs is disabled), and the 1 GHz power4 CPU in the 4-way IBM eServer pSeries 630/6C4.
In the MATRIX-89 benchmark, the matrices were of order 10, 20, 30,..., 100, the summed CPU times of Table 10 referring to 100 diagonalizations of order 10 matrices, 90 of order 20 matrices, and so on up to 10 diagonalizations for matrices of order 100.
The benchmark is specifically designed to work with datasets much larger than the available cache on any given system, so that the results are (presumably) more indicative of the performance of very large, vector style applications.

The Dhrystone benchmark exists in equivalent Ada, Pascal and C versions, which are all available from netlib@ornl.gov. Dhrystone measures the time to execute its main loop and sets this time into relation with a fixed reference time, the result being a performance index given in "Dhrystones per second".
The four parts of the WINTACH benchmark were then modeled after these profiles, so that the percentage of certain GDI (graphics device interface) calls found in the profiles is also present in the benchmark.
Whetstone performance depends on the speed of the coprocessor as well as on the speed of the CPU, while LLL and Linpack place a heavier burden on the coprocessor/FPU.

 What is Whetstone? CPU Benchmark Integer Performance Mflops   (Site not responding. Last check: 2007-10-11)
A comparison of the single processor Whetstone performance on a variety of machines, including vector supercomputers, minisupers, super-workstations and workstations, together with that obtained on a number of vector CPUs and on single nodes of various MPP machines.
The primary aim of this benchmark is to provide a performance measure of both floating point (FP) and integer arithmetic; thus while trends in the VL Mflop ratings are of interest, only a small part of the total CPU time is actually involved in these operations.
Results from the older MATRIX-89 benchmark are no longer listed as the overall run times are so small on the current generation of hardware to be of little use.

 Whetstone Benchmark History and Results
Brian Wichmann modified the interpreter to record statistics on the intermediate Whetstone instructions and produced a suite of simple statements which could be used to evaluate the efficiency of compilers and overall performance of a processor (see ICL KDF9 benchmark results in the table - the first is for the Whetstone Interpreter).
By this time, the Whetstone benchmark speed rating had become the default definition of minicomputer MIPS (Millions of Instructions Per Second), its significance being exaggerated when a minicomputer supplier somehow acquired the table of Whetstone benchmark results and published some of them in the computer press with the heading "Now who has the fastest minicomputer".
Whetstone performance ratings are known to have been a serious consideration in the design of the Digital VAX systems and other minicomputers of the same vintage, where some were reluctant to publish double precision results which did not match VAX speeds.

The Loop benchmark was originally created to factor out loop overhead in benchmarks that used loops to artificially increase a benchmark's running time rather than increase the number of operations at the source level.
