Abstract

The invention provides an extended interconnection network and a routing algorithm thereof. The extended interconnection network comprises a basic interconnection network and an additional I / O sub-network, wherein the basic interconnection network is formed by interconnecting multiple universal switchboards by adopting a standard topological structure; the additional I / O sub-network comprises at least one Plus switchboard; each Plus switchboard is connected with a HyperPort port of each corresponding universal switchboard in the basic interconnection network through a HyperPort port of the Plus switchboard to build a HyperPort link; and other ports of each Plus switchboard, except for the HyperPort port, are connected with I / O nodes. The extended interconnection network can meet a calculation requirement for calculating intensive applications, and is compatible with a special application scene of an I / O intensive application.

Description

technical field [0001] The invention relates to the technical field of high-performance computing interconnection network, in particular to an extended interconnection network and a routing algorithm thereof. Background technique [0002] Typical high-performance computing applications are mainly computing-intensive applications, such as ocean current simulation, scientific computing, etc. Computation-intensive tasks are characterized by a large number of calculations that consume CPU resources, such as calculating pi, decoding high-definition videos, etc., all relying on the computing power of the CPU. [0003] The application load of high-performance computing generally has local characteristics: spatial locality and / or temporal locality. Communication locality has an important impact on computational efficiency. The direct network allows the effective use of communication locality, and has more advantages than the indirect network. For example, the Mesh grid is more sui...
