Network management method, program, and system
First Claim
1. A network management method that manages an interconnection network of a parallel computer system in which switch devices for computer are provided to a plurality of computers, respectively, a predetermined number of physical lines for the switch device for computer are bound to form a logical line, and the physical lines forming the logical line interconnect the other switch devices for computer via a plurality of switch devices for relay, the network management method comprising:
- a data transmission speed obtaining step in which a data transmission speed required among the computers is obtained;
a switch shutting-off step in which, when the data transmission speed required among the computers is judged to be lower than a line transmission speed determined by the number of physical lines for any switch device for relay, power of the whole switch device for relay that has been judged is turned off to shut off the switch device for relay from the interconnection network; and
a switch resetting step in which, when a data transmission speed after the shutting-off is judged to be higher than the line transmission speed determined by the number of physical lines for the switch device for relay in the shutting-off state, power of the whole switch device for relay in the shutting-off state is turned on to allow the switch device for relay to return to the interconnection network.

Abstract
An interconnection network is provided with switch devices for computers for a plurality of computers, respectively, a predetermined number of physical lines for switch devices for computers are bound to form each of logical lines, the physical lines forming the logical lines interconnect the other switch devices for computer via a plurality of switch devices for relay to form a parallel computer system. When a data transmission speed required between the computers is judged to be lower than a line transmission speed determined by the number of physical lines of any switch device for relay, switch setting-off unit turns off power of the whole switch device for relay that has been judged to shut off the switch device for relay from the interconnection network.

11. A computer-readable storage medium which stores a network management program for a computer of a network management apparatus that manages an interconnection network of a parallel computer system in which switch devices for computer are provided to a plurality of computers, respectively, a logical line is formed by binding a predetermined number of physical lines for the switch device for computer, and the physical lines forming the logical line interconnect the other switch devices for computer via a plurality of switch devices for relay, the network management program comprising executing:
-
a data transmission speed obtaining step in which a data transmission speed required among the computers is obtained; a switch shutting-off step in which, when the data transmission speed required among the computers is judged to be lower than a line transmission speed determined by the number of physical lines for any switch device for relay, power of the whole switch device for relay that has been judged is turned off to shut off the switch device for relay from the interconnection network; and a switch resetting step in which, when a data transmission speed after the shutting-off is judged to be higher than the line transmission speed determined by the number of the physical lines for the switch device for relay in the shutting-off state, power of the whole switch device for relay in the shutting-off state is turned on to allow the switch device for relay to return to the interconnection network. - View Dependent Claims (12, 13, 14, 15, 16)

17. A network management system comprising:
-
an interconnection network of a parallel computer system in which switch devices for computer are provided to a plurality of computers, respectively, each logical line is formed by binding a predetermined number of physical lines for the switch device for computer, and the physical lines forming the logical line interconnect the other switch devices for computer via a plurality of switch devices for relay; and a network management apparatus that manages the interconnection network, wherein the network management apparatus is provided with a data transmission speed obtaining unit that obtains a data transmission speed required among the computers;
a switch shutting-off unit that turns off power of a whole switch device for relay that has been judged to shut off the switch device for relay from the interconnection network when the data transmission speed required among the computers is judged to be lower than a line transmission speed determined by the number of physical lines for any switch device for relay; and
a switch resetting unit that turns on power of the whole switch device for relay in the shutting-off state to allow the switch device for relay to return to the interconnection network when a data transmission speed after the shutting-off is judged to be higher than the line transmission speed determined by the number of the physical lines for the switch device for relay in the shutting-off state. - View Dependent Claims (18, 19, 20)
