Background

Distributed computing is hard, not at last because of the difficulties involved to efficiently coordinate and communicate between the individual application components. While the SAGA advert API (see GFD-P.177) addresses those needs for infrequent exchanges of small data items, a more performance oriented message API covering a variety of communication patterns is required for a large set of use cases. An respective SAGA API extension (see GFD-P.178 has recently been submitted as proposed OGF recommendation, a reference implementation is needed to gather experiences with that API in a variety of use cases.

Project Goals

A performant implementation of the SAGA Message API extension is planned to allow to exchange large, i.e. O(10MB), opaque pieces of data (messages) via a (a) point2point, (b) client/server, and (c) publish/subscriber patterns. The channel setup should be able to penetrate firewalls (via splicing), and should be ssh secured.

Project Description

Implementation of a message API adaptor as described above.

Project Requirements

Advanced C++ and Unix network programming skills. The use of external networking libraries, like ZeroMQ or boost-asio are explicitly encouraged, where appropriate.
