Marek, Could the nonsymmetry be introduced by the fact, that I use the fully > distributed setting (in the way of Step-40)? > Not if you have done it correctly. ;-) In the end, the represented operator is the same. Constraints don't change the symmetry either since the matrix A is essentially replaced by C^TAC where C repesents the homogeneous part of the constraints (assuming constraints are given as Cx=k).
