The LINPACK benchmark measures computer speed by solving linear equations. There are three benchmarks: LINPACK Fortran n=100, LINPACK n=1000, and Highly Parallel Computing. The results are published in a report and compared to other systems. LAPACK has replaced LINPACK in some applications.
A LINPACK benchmark is a way to measure the speed of a computer. It stands for linear equation software package. There are three different LINPACK benchmarks: LINPACK Fortran n=100, LINPACK n=1000, and the Highly Parallel Computing Benchmark. They compare computer performance when solving a system of linear equations.
There are many different benchmarks used to evaluate or measure computer speed and performance. The LINPACK benchmark was created in 1979 by Jack Dongarra, a computer science professor at the University of Tennessee. The LINPACK benchmark was created because Dongarra and his collaborators were working on a book and needed a way to compare computer performance for its readers, so they wrote a program that performed certain mathematical calculations and created a baseline for the comparison.
The LINPACK benchmark program was originally written in the Fortran programming language. Fortran means translation of formulas. It used to translate math formulas into computer code, making it ideal for the LINPACK benchmark application.
There are three different LINPACK benchmarks. LINPACK Fortran n=100 is used to measure the speed of a computer in solving linear equations using a matrix or matrix of numbers containing 100 numbers. To return an accurate result, this benchmark must be run exactly as written. No changes are allowed even to the comments, which do not directly affect the functioning of the program.
The LINPACK n=1000 benchmark is similar to the n=100 benchmark. It is used for an array of 1000 numbers. This benchmark should also be run exactly as written.
The Highly Parallel Computing Benchmark is different from the other two benchmarks. Users can specify the size of the problem and the software to use. This measures the best possible computer performance under ideal conditions.
The results of LINPACK benchmark tests are reported in several ways. They are published in the LINPACK benchmark report, subtitled Performance of Various Computers Using Standard Linear Equations Software. It lists the performance of many computer systems in the industry and can be found online. There is even a website called TOP500 that lists systems that have scored in the top 500 in benchmarks. The performance of any individual computer may vary from the published benchmark results for that model, because every computer is different.
In some applications, LINPACK has been replaced by LAPACK. LAPACK stands for Linear Algebra Pack. Restructure the original software for greater efficiency. The program was originally written in Fortran 77, but has now been translated for use in several other programming languages.
