. High − order 丘ni 七 e difference schemes suited to super vector − compu 七 er are proposed fQr numerica 正solution of 七 he 七 hree − dimensional Po董 sson equation . These difference schemes are derived from modification of the right − hand side of the equation . We consider the schemes which are defined on a cube using ste ロ cils with the nQde points which are located on 七 he gridpoints and on the intermediate point between gridpoints . Several high − order difference schemes are examined in view
