Paragraph: A Graphical Tuning Tool for Multiprocessor Systems
Distributing computational load to many processors is a critical issue for efficient program execution on multiprocessor systems. Finding a good load distribution algorithm is one of the most important research topics for parallel processing. Tools for evaluating load distribution algorithms are very useful for this kind of research. This paper describes a system called ParaGraph that gathers periodical statistics of the computational and communication load of each processor during program execution, in both the higher level of programming language and lower level of implementation, and presents them graphically to the user
