We consider a convex optimization problem with a quadratic cost function. Wepartition the data of the problem into a set of processors. We use the Message Passing Interface (MPI) and develop parallel implementations of two iterative methods for the solution of the optimization problem, the Gradient Descent and the Block Coordinate Descent (BCD). We test the convergence properties of the algorithms under various circumstances, by calculating the speed of convergence and the total communication cost.
