METHOD OF SELECTING FUNCTION FOR PERFORMANCE EVALUATION MODELING

摘要

PPROBLEM TO BE SOLVED: To provide a method of automatically selecting functions more highly contributing to performance evaluation based on the program operation history of a computer system. PSOLUTION: A method of extracting executed functions included in the operation history of a computer program includes: a step of accepting an operation history; a step of assigning the functions to the nodes of a tree structure by using the calling relation of the functions included in the accepted operation history; and a step of dealing with the execution time or memory usage as quantitative information, and extracting the functions under such conditions that the total of the quantitative information accessory to the functions exceeds the product of the quantitative information accessory to the whole and a prescribed rate. The step of extracting the functions may extract the functions under such conditions that the number of the functions exceeds a lower limit, and does not exceed an upper limit. Furthermore, this method of extracting the functions may include a step of generating an execution trace by using the extracted functions. PCOPYRIGHT: (C)2010,JPO&INPIT
