The Durra Application Debugger/Monitor

Durra is a language designed to support the construction of distributed applications using concurrent, coarse-grained tasks running on networks of heterogeneous processors. An application written in Durra describes the tasks to be instantiated and executed as concurrent processes, the types of data to be exchanged by the processes, and the intermediate queues required to store the data as they move from producer to consumer processes. This report describes the Durra application debugger/monitor, a program that works in conjunction with the Durra runtime software to help the developer locate errors and/or performance bottlenecks in a Durra application.
