Parallel Program Debugging with MAD — A Practical Approach

Abstract

Abstract. Debugging parallel programs can be very time-consuming and tedious, because the multiplicity of communicating processes increases the complexity of a program and the probability of incorrect behavior. Solutions are provided by debugging tools, which try to offer meaningful ways to investigate errors and their original causes. The MAD environment is a debugging toolset, which focuses on parallel and distributed programs. This paper discusses the application of MAD to real-world programs with practicability and usability as the main goals. The observations are based on a series of debugging sessions conducted for a specific application of theoretical physics, with the opinions of the tool developer on one side and the view of the application developer on the other side.

Visualizing Arrays in the Eclipse Java IDE

“…The Vcc program animation tool [7] has a dedicated view for visualizing numerical arrays as bar charts or line charts. Kranzlmüller et al ([8], [9]) proposed a method for visualizing multi-dimensional numerical arrays for debugging parallel programs. The above presented methods and tools either do not focus on arrays or are restricted to numerical arrays.…”
