摘要
介绍了为曙光机群系统设计实现的并行调试器DCDB。DCDB同时支持调试MPI或PVM、C或Fortran的并行应用程序，实现了记录/重放并行调试功能，支持循环调试，解决了并行调试时并行程序的不确定性问题。DCDB采用Client/Server/Client结构，具有友好的图形用户界面，系统主要采用Java语言开发，具有良好的可移植性和可扩展性。
This paper introduces the design and implementation of dawning cluster debugger (DCDB) which is developed for cluster system. DCDB supports to debug MPI or PVM parallel program, which is C code or Fortran code. It implements the record/replay parallel debugging technique and supports the cyclic debugging, which resolves the indeterminacy problem in the parallel debugging. DCDB employs the Client/Server/Client architecture and has a friendly GUI. DCDB is mainly developed by Java language and it has good portability and scalability.
