Create the distributed modified sparse row (MSR) matrix: bindx/val. For a submatrix of size m-by-n, the MSR arrays are as follows: bindx[0] = m + 1 bindx[0..m] = pointer to start of each row bindx[ks..ke] = column indices of the off-diagonal nonzeros in row k, where, ks = bindx[k], ke = bindx[k+1]-1 val[k] = A(k,k), k < m, diagonal elements val[m] = not used val[ki] = A(k, bindx[ki]), where ks <= ki <= ke Both arrays are of length nnz + 1.
