A framework for unit testing with coarray Fortran

摘要: Parallelism is a ubiquitous feature of modern computing architectures; indeed, we might even say that serial code now automatically legacy code. Writing parallel poses significant challenges to programs, and often error-prone. Partitioned Global Address Space (PGAS) languages, such as Coarray Fortran (CAF), represent promising development direction in the quest for trade-off between simplicity performance. CAF programming model allows smooth migration from However, despite simplicity, refactoring migrating it versions still error-prone, especially complex softwares. The combination unit testing, which drastically reduces defect injection, therefore very appealing prospect; however, requires appropriate tools realize its potential. In this paper, present first CAF-compatible framework tests, developed an extension Parallel Unit Test (pFUnit).
