Perform a sparse LDL^t factorization using PaRSEC 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.

Generate the PaRSEC taskpool object for the LDL^t factorization with 1D kernels.
The function only return the object that describes the LDL^t factorization of a sparse hermitian matrix A. The factorization has the form
\[ A = L \times D \times L^t \]
where L is a sparse lower triangular matrix unitary on the diagonal, and D a diagonal matrix.
In this object, all operations are panel based operation which might result in lower parallelism for large problems.
