[DOC File]Parallel Implementations of Direct Solvers
https://info.5y1.org/system-of-equations-with-elimination-solver_1_8e4abe.html
A system of equations Ax=b is usually solved in two stages. First, through a series of algebraic manipulations, the original system of equations is reduced to an upper-triangular system of the form. This can be written as Ux=y, where U is a matrix in which all subdiagonal entries are zero. That is U[i,j] = 0 if i > j, otherwise U[i, j] =.

[DOC File]Parallel Solution of Unstructured Sparse Matrix Equations
https://info.5y1.org/system-of-equations-with-elimination-solver_1_aa2dc4.html
Sparse matrix solution is encountered in many modelling and simulation problems such as ODE solvers [1], finite element analysis [2] and circuit simulation [3; 4]. These programs often use implicit methods for numerically solving systems of differential equations which transform the problem into a system of nonlinear equations.

https://info.5y1.org/system-of-equations-with-elimination-solver_1_79fce7.html
The Givens algorithm for solving a linear system with N equations can be decomposed into two computational stages. The first is the triangulation of the initial matrix; this stage is represented by the execution of the elimination block N times. The second stage is the back-substitution block that solves the triangular matrix.
