摘要

由于大型科学代码很少是静态对象,开发人员经常面临解释新旧版本之间差异的繁琐任务。在本文中,我们描述了一种称为相对调试的新技术,它通过将修改后的代码与正确的参考代码进行比较的过程自动化来解决这个问题。我们通过将一个名为Guard的相对调试器应用于大型大气环流模型中的一系列调试问题来检验相对调试技术的实用性。我们的经验证实了这种做法的有效性。使用Guard,我们能够验证一个新的连续版本的大气模型,并在短时间内确定平行版本中显著差异的来源。

Relative Debugging and its Application to the Development of Large Numerical Models
Because large scientific codes are rarely static objects, developers are often faced with the tedious task of accounting for discrepancies between new and old versions. In this paper, we describe a new technique called relative debugging that addresses this problem by automating the process of comparing a modified code against a correct reference code. We examine the utility of the relative debugging technique by applying a relative debugger called Guard to a range of debugging problems in a large atmospheric circulation model. Our experience confirms the effectiveness of the approach. Using Guard, we are able to validate a new sequential version of the atmospheric model, and to identify the source of a significant discrepancy in a parallel version in a short period of time.
