A precise execution timing routine for engineering software evaluation

Program execution time is one of the major parameters used in the performance evaluation of the computationally intensive engineering software. Unfortunately, computer systems based on Microsoft Windows platforms under the Intel's x86 architecture lack sufficiently precise timing capabilities needed for performing measurements of some short executions. Therefore, in this paper a precise timing routine capable of successfully measuring executions at the processor clock cycle level is proposed and discussed. Furthermore, its complete source code is provided. Finally, the utility of this timing routine is demonstrated on an example of comparative efficiency evaluation of two well-known two-point function approximations.
