In the present paper, the methodology of interoperability between ITBL and Grid-TLSE is described. Grid-TLSE is an expert website to provides user assistance in choosing the right solver for its problems and appropriate values for the control parameters of the selected solve. The time to solution of linear equation solver strongly depends on the type of problem, the selected algorithm, its implementation and the target computer architecture. Grid-TLSE uses the Diet middle ware to distribute computing tasks over the Grid. Therefore, extending the variety of computer architecture by Grid middle ware interoperability between Diet and ITBL has a beneficial impact to the expert system. To show the feasibility of the methodology, job transfering program as a special service of Diet was developed.
