説明

A typical implementation of scientific applications includes a large number of iterative calculations. For performance optimization, these calculations are often partitioned, grouped, and reordered for execution. Since this refactoring is repeatedly performed during development, it is one of the major source of bugs and thus tool support is necessary for debugging. This study discusses this problem and proposes tool support through a testing framework. This testing framework can help developers perform the tests we call calculation coverage testing. It investigates whether the grouped calculations cover all the calculations performed by the original (and often naively implemented) program. It also investigates whether their execution order is correct. To demonstrate this idea, we also presents HPCUnit, our prototype testing framework for Java, and then reports an empirical study applying it to the Java Grande Forum Benchmark Suite.
