ABSTRACT:
There is disclosed a node booting method in a high-speed parallel computer. Other than the method in which the system using a conventional network down loads the operating system kernel image from the boot server, the method according to the present invention provides an environment by which a boot can be progressed in parallel and a boot progress state can be monitored through a console terminal, thus improving a boot speed. The node booting method according to the present invention is comprised of a first step of finding a logical boot path using a node construction table managed by a firmware; a second step of determining boot subject nodes so that copy of an operating system kernel image can be made simultaneously; a third step of copying effective portions of the operating system loaded at the memories onto the subject nodes; a fourth step of informing a boot node of the node state and to display the boot progress state on a console terminal at the start and end time of the booting; and a fifth step of simultaneously starting execution at the remaining portions of the copied operating system when the kernel image are completely copied onto all the nodes.
