Hierarchical crossbar interconnection network for a cluster-based parallel processing computer
First Claim
1. A hierarchical crossbar interconnection network for parallel processing computer, having clusters of nodes and crossbar networks, comprising:
- a crossbar network is composed of "n" (any integer) number of crossbar switches, eight links for connecting lower level clusters or processing nodes, and two links for connecting other clusters;
a low-level cluster is formed by connecting a maximum of eight processing nodes between two crossbar networks;
a high-level cluster is formed by connecting a maximum of eight low-level clusters between four crossbar networks; and
a hierarchical crossbar interconnection network for a cluster-based parallel processing computer, having low delay latency is formed by directly connecting two low-level clusters or by directly connecting two high-level clusters.

Abstract
The present invention relates to a hierarchical crossbar inter-connection network for a cluster-based parallel processing computer. A crossbar network is composed of the "n" number of crossbar switches which is byte sliced, eight links for connecting eight nodes, and two links for connecting other clusters. In addition, one low-level cluster is formed by connecting a maximum of eight processing nodes between the two crossbar networks, and one high-level cluster is formed with a maximum of eight low-level clusters and the four crossbar networks. Moreover, one next high-level clusters formed with a maximum of eight high-level clusters and the eight crossbar networks for scalability.

9. A hierarchical crossbar interconnection network for cluster-based parallel processing computer, comprising:
-
a crossbar network having a single stage and being composed of "n" number (any integer) of byte-sliced crossbar switches, eight links for connecting lower level cluster (or processing nodes), and two links in order to construct a higher level cluster by connecting links of additional crossbar networks or to construct two same level clusters by directly connecting links of other same level cluster; a low level (or level
0) cluster formed by connecting a maximum of eight processing nodes between two crossbar networks in the manner that one link of each of the processing nodes is connected to one of the two crossbar networks and the other link of each of the processing nodes is connected to the other of the two crossbar networks; anda high-level (or level
1) cluster formed by connecting a maximum of eight low-level clusters between four additional crossbar networks in the manner that four links of each of the low-level clusters are respectively connected to each link of the four crossbar networks. - View Dependent Claims (10, 11, 12)
