Abstract : Benchmarks that measure time values using a standard system clock often employ a dual loop design. One of the important assumptions of this design is that textually identical loop statements will take the same amount of time to execute . This assumption was tested on two bare computers with Ada test programs and has been demonstrated to be inaccurate in these specific test cases. Keywords: Validation; Variations; Accuracy. (Author)
