Compiling and Building TAUCS a library of sparse linear solvers
I would like to share the following information to all the iMechanica users interested in using TAUCS a library of sparse linear solvers. TAUCS is among the most used libraries of sparse linear solvers and, to my knowledge, its closest equivalent library is SuperLU. For your reference, TAUCS is used in the commercial software Mathematica by Wolfram Research. Its source code can be downloaded from
http://www.tau.ac.il/~stoledo/taucs
In every numerical implementation which leads to large sparse matrices the use of such type of libraries is often needed. That is because the numerical solution of sparse linear systems becomes an important step and nobody would like to fail in this stage. In this regard a good library of sparse linear solvers may be of help in speeding up the numerical computation. Because there is no support available for TAUCS it is not straightforward to get into it, but once the user
has successfully ran his/her first TAUCS example all will go through smoothly. Motivated in part by the latter a forum on TAUCS has been started in
http://groups.google.com/group/matrixprogramming?hl=en
which is managed by Evgenii Rudnyi from CADFEM GmbH, Germany. Egvenii, myself and other users in the forum have contributed to an online guide to compile and build TAUCS under Win32 that you can consult in
http://matrixprogramming.com/TAUCS/
The latter is the summary of all the issues addressed in the forum. Although the same principles can be applied to build TAUCS under Linux, we have chosen Win32 because some particular difficulties arise in this OS. I believe that this
guide will help the new user to use TAUCS easily and succesfully.
