| | | The Case for Collective Pattern Specification
(Jun. 2010, Accepted at the 1st ACM Workshop on Advances in Message Passing (AMP'10) )
AbstractMany scientific applications are written in
a Bulk Synchronous Parallel style, in which regions of pure
computation are separated by communication operations. Unless an
existing MPI collective operation can be used, these communication
operations are usually written as separate message sends and
receives, making analysis and optimization difficult. This style of
communication also reduces readability and maintainability by hiding
the overall collective pattern in a maze of individual messages.
Instead we advocate directly specifying (collective) communication
operations in a domain-specific language. We further classify
applications by their communication patterns, in particular with
respect to different nodes' knowledge of the applications' patterns
and the frequency of pattern changes, showing how a language would
benefit each of these classes of applications and the requirements
for such a language.
