Research and Design of a Parallel Debugging Interface in a New Parallel Debugger Framework

Parallel debugger is crucial for improving the efficiency of parallel programming development. Parallel debugging interface is the basis of parallel debugging. This paper puts forward a parallel debugger design method of a new interactive, Internet-oriented, extensible parallel debugger framework based on the research of a number of parallel debugging interfaces´ design methods and advantages and disadvantages analysis, and gives a careful implementation of a new parallel debugging interface in this new parallel debugger framework. In this framework users can execute debugging job remotely. The debugging back-end servers are deployed in clusters with various remote debugging details transparent to users. Tests showed that the parallel debugging interface designed in this paper not only properly meets the needs of user´s debugging requirement, but also have a good time performance. Under the test circumstances, it took about 11 seconds to startup 256 remote parallel debugging processes on 3 computing nodes.
