Embodiment Construction

[0025] The present invention is described in detail below in conjunction with accompanying drawing:

[0026] The polling mapping method that the present invention proposes, specific technical scheme is as figure 1 Shown:

[0027] The first step is to calculate the number of I / O forwarding nodes in the supercomputer, denoted as n. The numbers of the I / O forwarding nodes are ION 0 ,ION 1 ,...,ION n-1 . Note that one I / O forwarding node can serve computing nodes alone, or multiple I / O forwarding nodes can serve computing nodes in groups. If grouped, multiple I / O forwarding nodes poll the I / O request of the service computing node, but this group of I / O forwarding nodes can be considered as one I / O forwarding node logically, when computing I When / O forwards the number of nodes, it is only counted once.

[0028] The second step is to calculate the number of computing nodes in the supercomputer, denoted as m. The numbers of computing nodes are respectively CN 0 ,CN 1 ,...,...

Abstract

The invention discloses a super computer I/O forwarding node polling mapping method, which comprises the following steps of: calculating the number of I/O forwarding nodes in a super computer, and recording the number as n; numbering the n I/O forwarding nodes to be ION0, ION1,..., IONn-1 respectively; calculating the number of calculation nodes in the super computer, and recording the number as m, wherein the serial numbers of the calculation nodes are respectively CN0, CN1,..., CNm-1; mapping the calculation node CNi to an I/O forwarding node IONi% n by adopting a polling mapping calculationmethod; modifying I/O forwarding node configuration on each computing node, namely modifying the I/O forwarding node configuration from the traditional partition mapping method to IONi% n of a polling mapping method for the computing node CNi; processing all I/O requests sent from the computing node CNi by the I/O forwarding node IONi% n; after the I/O forwarding node configurations on all the computing nodes are modified, restarting the I/O forwarding services on the computing nodes, so that the configurations take effect, and the method solves the problem of load imbalance among the I/O forwarding nodes.

Description

technical field [0001] The invention relates to the field of supercomputer storage architecture, in particular to a supercomputer I / O forwarding node polling mapping method. Background technique [0002] Modern supercomputers generally adopt a storage architecture that includes an I / O forwarding layer. Computing nodes send I / O requests for data reading and writing to I / O forwarding nodes, and I / O forwarding nodes replace them from the storage system. access data in. The current mapping method between computing nodes and I / O forwarding nodes is that all computing nodes in the system are divided into partitions with the same number of I / O forwarding nodes, and adjacent computing nodes (like in the same cabinet) are in In the same partition, each I / O forwarding node is responsible for serving the computing nodes in a partition. This mapping method is easy to manage and maintain, but it faces serious load imbalance problems in the actual production application environment. ...
