Timing Variation in Dual Loop Benchmarks

  • October 1987
  • By Neal Altman, Nelson W. Weiderman
  • This report disproves one of the major assumptions of dual loop benchmark testing by testing two bare computers with Ada test programs.

  • 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.
