Abstract
This paper reports on and compares experiences in using the languages. We concentrate on the interplay between object orientation and parallelism/distribution, and other issues of coding task parallelism. In particular, we discuss the realization of patterns such as objects that internally contain distributed arrays, and suggest improvements such as support for activity-local and place-local data, as well as scalar variable-based reduction. Our study is based on Unbalanced Tree Search (UTS), a well-known benchmark that uses task pools.
