SuiteSparse:ParU parallel multifrontal sparse LU solver wrapper.
ParU computes a sparse LU factorization of a real square matrix and uses OpenMP tasks and parallel BLAS in its numerical phase. The matrix values are shared with ParU through a non-owning CHOLMOD view. Rodin sparse matrices use 32-bit indices whereas ParU requires 64-bit indices, so only the two CSC index arrays are converted.
