◆ starpu_ssytrf()

void starpu_ssytrf	(	pastix_data_t *	pastix_data,
		sopalin_data_t *	sopalin_data
	)

Perform a sparse LDL^t factorization using StarPU runtime.

The function performs the LDL^t factorization of a sparse symmetric matrix A. The factorization has the form

\[ A = L \times D \times L^t \]

where L is a sparse lower triangular matrix orthogonal on the diagonal, and D a diagonal matrix.

The algorithm is automatically chosen between the 1D and 2D version based on the API parameter IPARM_TASKS2D_LEVEL. If IPARM_TASKS2D_LEVEL != 0 the 2D scheme is applied, the 1D otherwise.

Parameters

[in,out]	pastix_data	The pastix_data structure that describes the solver instance.
[in,out]	sopalin_data	Solver matrix information structure that will guide the algorithm.
