TridiagLU

swMATH ID: 12620
Software Authors: Ghosh, Debojyoti
Description: TridiagLU Repository: Parallel (MPI) direct solver for a tridiagonal system of equations: Contains the functions for solving a non-periodic tridiagonal system of equations in parallel (LU decomposition). The system is solved by rearranging the points: grouping the last point of each sub-domain at the end. The reduced system is solved by either the recursive-doubling or gather-and-solve techniques. A test code is provided to check test these functions and their walltimes.
