VIZIR: an integrated environment for distributed program visualization
Mushuai Hao, Alan H. Karp, Abdul Waheed, Mehdi Jazayeri · 2002
VIZIR provides an integrated mechanism for on-line debugging, performance analysis, and data visualization of message-passing parallel applications. The current VIZIR includes: (1) a mechanism to multicast window-based commands, message passing and program execution events among tasks; (2) the ability to select groups of tasks to interact these events; (3) a means to report when these events cause errors in the tasks; and (4) ad hoc visualization of distributed arrays using existing visualizers.>
