We would like to establish, through analyzing the CPU-measurements, the performance model for a number of numerical methods when applied in different model problems. All the simulators, i.e. the software programs carrying out the simulations, have been developed using Diffpack which is a generic C++ library based on object-oriented programming techniques. Therefore, the established performance models may offer a rough prediction of real CPU-time consumption by actual Diffpack simulators for practical problems. Additionally, the report can also be regarded as an investigation of the computational efficiency of the current Diffpack implementations. Last but not least, we wish to point out to Diffpack programmers some implementation issues that may affect the performance of the simulators. } }
