.... and usergenerated commands (e.g. system signals and client tool requests) with a well defined set of events and an implementation independent operational semantics, is a major step forward to the integration of parallel debuggers in more complete and complex program development environments [7, 9]. The OMIS (proposed) Standard The On line Monitoring Interface Specification (OMIS) 11] aims to define an open interface to connect software development tools for parallel software, including e.g. debuggers and performance analyzers. Concerning debugging, OMIS has a more broad scope than ....

....Using the DDBG Debugger In this section we briefly discuss our experimentation with the interfacing of the DDBG system and two high level tools of a parallel software engineering environment: the STEPS and the GRAPNEL tools. More detailed descriptions of these tools and interfaces is given in [21,14,18 20,9,23]. 4.1 Tool Composition for Testing and Debugging In our project we have given great consideration to the search of a close integration of static analysis and dynamic analysis methods in order to guarantee the final quality of the parallel software. The development of a methodology and tool to ....

....control. An automated tool determines a valid sequence of intermediate states that lead the application to the desired state, and then the technique described in (2) is applied. This specification file can be generated by a multitude of tools, such as static or dynamic testing tools [13] 17] or by a monitor that traces all the processes interactions during the application (as presented in this paper) The re execution of a parallel or distributed application requires a two phase process: ffl Phase 1: Recording In this phase, information is collected on each node, in order to ....

....e.g. converting a DEIPA step command into a set of DDBG set breakpoint and continue execution commands. It also supports the required process control, e.g. setting variables in an if then else statement, so that each process is forced to follow the path that is specified by the TeSS file. In [16] there is a complete discussion of DDBG and STEPS integration. The DDBG support for multiple simultaneous client tools has been used here. The DEIPA tool is used to control the execution of all the application processes as explained, and the DDBG console and or GUI can be used to provide a more ....
