Which of the following is a correct statement about Gaussian elimination with partial pivoting? If partial pivoting is used with an implicit exchange of columns indices, the factors are always viewed as triangular matrices. If partial pivoting is used with an implicit exchange of columns indices, the factors are no longer viewed as triangular matrices. This method consists of selecting rows known as the pivot column and starts by exchanging with other columns. This method can only work on a specific parallel algorithm.what is the difference between row-wise and column-wise 1-D partitioning? The pivot search is distributed in column-wise pipelining, not row-wise partitioning. Column-wise partitioning is better for partial pivoting than a row-wise partitioning. There is no difference between 1-D and 2-D partitioning. Row-wise partitioning is better for partial pivoting than a column-wise partitioning
