Xab: A Tool for Monitoring PVM Programs

نویسنده

  • Adam Louis Beguelin
چکیده

Xab (X-window Analysis and deBugging) is a tool for run time monitoring of PVM (Parallel Virtual Machine) programs. PVM supports the programming of a network of heterogeneous computers as a single parallel computer. Using Xab, PVM programs can easily be instrumented and monitored. Xab uses PVM to monitor PVM programs. This makes Xab very portable but it leads to interesting issues of how to make Xab peacefully coincide with the programs it monitors. Xab consists of three main components, a user library , a monitoring program, and an X windows front end. The user library provides instrumented versions of the PVM calls. The monitoring program runs as a PVM process and gathers monitor events in the form of PVM messages. The Xab front end displays information graphically about PVM processes and messages. This paper discusses the design, implementation, and use of the Xab tool. Related work is brieey presented and contrasted with the approach taken with Xab. How Xab works and how it is used are discussed in detail. Finally, the current status of Xab is presented along with future directions of where the research may go from here.

Monitoring PVM Programs Using the DAMS Approach

Monitoring tools are fundamental components of a development environment as they provide basic support for performance evaluation, debugging, and program visualization. We describe our experiments with several monitoring tools for PVM, namely XPVM, developed at ORNL, Tape/PVM, developed at IMAG Lab, and DAMS, developed at UNL. These tools are compared and their use is described to support instr...

Executing and Monitoring PVM Programs in Computational Grids with Jini

This paper presents a way to build a computational Grid for PVM programs. The Grid applies Jini to handle the dynamically changing set of participants, and to make the communication between Grid-clients and Grid-machines possible. In case of a PVM-Grid the grid-resources are Parallel Virtual Machines. Our system provides a high-level interface for them, which through the users can submit their ...

An Open Monitoring System for Parallel and Distributed Programs

The on-line monitoring interface specification OMIS provides means for developing more powerful tool environments for parallel and distributed systems. It specifies the interaction between any tool and a monitoring system which is responsible for observing and manipulating the programs’ execution. By having this well defined interface it is now possible to concurrently use several tools of poss...

ValiPVM - A Graphical Tool for Structural Testing of PVM Programs

This work presents ValiPVM, a testing tool for C/PVM parallel programs. This tool implements structural coverage criteria, using an architecture already employed for MPI programs. It supports generation and evaluation of test sets and considers the control, data and communication flows of PVM programs. ValiPVM has a graphical user interface, designed to facilitate the test execution, analysis o...
