◆ starpu_zpxtrf()

void starpu_zpxtrf ( pastix_data_t pastix_data,
sopalin_data_t *  sopalin_data 
)

Perform a sparse LL^t factorization using StarPU runtime.

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

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

where L is a sparse lower triangular 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_dataThe pastix_data structure that describes the solver instance.
[in,out]sopalin_dataSolver matrix information structure that will guide the algorithm.
