Abstract
Most parallel programming models provide a single generic mode in
which processes can exchange information with each other. However,
empirical observation of parallel programs suggests that processes
share data in a few distinct and specific modes. We argue that such
modes should be identified and explicitly supported in parallel
languages and their associated models. The paper describes a set of
information sharing abstractions that have been identified and
incorporated in the parallel programming language Charm. It can be
seen that using these abstractions leads to improved clarity,
expressiveness,efficiency, and portability of user programs. In
addition, the specificity provided by these abstractions can be
exploited at compile-time and at run-time to provide the user with
highly refined performance feedback.
