GENERIC PROGRAMMING OF PARALLEL APPLICATIONS WITH JANUS
Jens Gerlach · Parallel Processing Letters · 2002
Janus is a conceptual framework and C++ template library that provides a flexible and extensible collection of efficient data structures and algorithms for a broad class of data-parallel applications. In particular, finite difference methods, (adaptive) finite element methods, and data-parallel graph algorithms are supported. An outstanding advantage of providing a generic C++ framework is that it provides application-oriented abstractions that achieve high performance without relying on language extension or non-standard compiler technology. The C++ template mechanism allows to plug user-defined types into the Janus data structures and algorithms. Moreover, Janus components can easily be combined with standard software packages of this field.
