SuperLU Installation

NOTE: These intructions were updated in September 2005. They may not be kept up-to-date. Refer to the SuperLU documentation for more recent and more complete instructions.

SuperLU must be installed before Amesos_Superlu can be used. Follow these steps to install SuperLU on your system:

• Obtain the distribution from Xiaoye Li's SuperLU web site by clicking on the download link in the "SuperLU Version 3.0" (or more recent) section.
• Untar the SuperLU code in your Trilinos3PL directory.
• Build SuperLU
  • Follow the intructions in README (edit make.inc, 'make lib'), ignoring the section on MATLAB
  • Note:Trilinos3PL/config/SuperLU contains the make.inc files that I used.
• Run an example:
  • Follow the instructions in EXAMPLE/README:
    • cd EXAMPLE
    • make dlinsol
    • dlinsol < g10
  • Expected output:
