In this section, we compare the performance of MA62 with that of other codes in the Harwell Subroutine Library (HSL).
We anticipate that a version of MA42 which exploits zeros and allows the user to specify the minimum pivot block size will be included in a future release of the Harwell Subroutine Library.
In this section, we compare the performance of the frontal code MA62 with other codes in the Harwell Subroutine Library that are also designed for solving symmetric positive-definite systems, namely the multifrontal code MA27 and the code VBAN, which is a development version of a new HSL code MA55.
An example of a code that is primarily designed for matrices with a symmetric pattern is the Harwell Subroutine Library (HSL) code MA41 [Amestoy and Duff 1989] that will also solve general unsymmetric systems by holding explicit zeros so that the unsymmetric matrix is embedded in one of symmetric structure.
