How to run the debugger in a distributed environment

摘要

The present invention relates to a method and apparatus for developing a program using a message passing interface (MPI) in a distributed environment while a distributed program is executed without a user's interference or assistance when an error is detected using a debugger, And a method of easily driving a debugger in a distributed environment by enabling a user to go directly to a debugging state. The feature is characterized in that, after driving a master debugger by a user, a message passing programming interface daemon drives each program module of an actual distributed program, A debugger core of each system in each of the program modules, an attachment to execute the program module in a state in which the program module can be debugged, a program to be debugged, And a step of receiving a command of the master debugger and performing an actual debugging operation after the signal transmission for the continuous execution of the module. Therefore, the present invention as described above enables the distributed program When debugging, the debugger can automatically acquire control of the program module to be debugged without user intervention, so that when the user executes the distributed program without user interference or assistance, the debugger can be immediately used to access the debugger It is effective in that there is.
