18 * This module contains all the subroutines and structures to perform the
19 * analyze step and prepare the numerical factorization and solve. It is
20 * composed of four main steps. The first one is the computation of the
21 * proportional mapping based on the elimination tree to attribute worker
22 * candidates to all nodes in the tree. The second one is the cutting step of
23 * the symbol matrix to generate more parallelism. Then, the simulation
24 * predict the best mapping out of the candidates and returns the associated
25 * static scheduling for the tasks. Finally, the local solver structure is
26 * created to control the numerical factorization and solve and store the
27 * problem data.
