This paper presents our experience developing applications in Jade, a portable, implicitly parallel programming language designed for exploiting task-level concurrency. Jade programmers start with a program written in a standard serial, imperative language, then use Jade constructs to describe how parts of the program access data. The Jade implementation analyzes this information to automatically extract the concurrency and execute the program in parallel. The resulting parallel execution is guaranteed to preserve the semantics of the serial program. We have implemented Jade as an extension to C on shared memory multiprocessors, a homogeneous message-passing machine and networks of heterogeneous workstations. To evaluate Jade, we obtained several complete scienti c and engineering applications and parallelized them using Jade. We then executed these applications on several computational platforms. We use this applications experience to evaluate Jade with respect to two properties: how...
