| Summary: | Hierarchical interconnection networks provide
high performance at low cost by exploring the locality that
exists in the communication patterns of massively parallel
computers. A Symmetric Tori connected Torus Network
(STTN) is a 2D-torus network of multiple basic modules,
in which the basic modules are 2D-torus networks that are
hierarchically interconnected for higher-level networks. We
also fold the STTN to minimize the length of the longest
wire of STTN. The folded network is called Folded Tori
connected Torus Network (FTTN). In this paper, we present
the architecture of the STTN and FTTN, addressing of
node, routing of message, and evaluate the static network
performance of STTN, FTTN, TTN, TESH, mesh, and torus
networks. It is shown that both the STTN and FTTN possess
several attractive features, including constant node degree,
small diameter, low cost, small average distance, moderate
bisection width, and high fault tolerant performance than
that of other conventional and hierarchical interconnection
networks. We further evaluate the longest wire length of
FTTN and compare it with other networks. We found that
the longest wire length of the FTTN is far lower than that
of other networks considered in this paper while keeping
good static network performance. It is just about (1/2mth)
of its rival STTN. |
