  abstract = { The primary purpose of this report is to collect some
		  information on the CPU-time consumption in a series of
		  typical numerical simulations for solving partial
		  differential equations (PDEs). 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. }
