Debugging is an essential part of parallel and distributed processing. However, developing parallel and distributed debugger is difficult. This is especially true for cluster computing where heterogeneity presents. In this paper, we first give a survey of the current debugging techniques and existing tools, and then present a client–server debugging model.(More)
This paper presents a client-server debugging model, describes the design and implementation of a portable, scalable, practical distributed debugger based on this model, and compares it with the related work. The distributed debugger based on the sequential debugger gdb or dbx can efficiently support debugging various PVM and MPI programs, and its(More)
Data mining refers to extracting or mining knowledge from large amounts of data. Among the various data mining tasks sequential pattern mining is one of the most important tasks. It has broad applications in several domains such as the analysis of customer purchase patterns, web access patterns, seismologic data, and weather observations. Sequential pattern(More)
