| The standart matrix solver included in the xnet programm "LAPACK" is too slow to solve a network like this. Faster solutions are sparse matrix solver. Two interfaces are included in xnet: For MA48 and Pardiso. Instructions to include these matrix solvers in the code can be found in the documentation of the code. We experienced problems for both with Linux: Pardiso should be much faster than MA48 needs a full compiled LAPACK library. This is included in the ifort compiler. Finally we succeeded in compiling Pardiso version with ifort. The program can be found here. | The standart matrix solver included in the xnet programm "LAPACK" is too slow to solve a network like this. Faster solutions are sparse matrix solver.
