摘要
A method controls the change in operating system in selected service nodes of a high- performance computer (CHP). The method includes: a step (i) of defining, for the selected service nodes, a reduced version of a new operating system to be installed, a boot kernel, a so-called “reference” tree node software image suitable for the new operating system and including a definition of an instantiation to be established in the service nodes, and an activation module capable of locally installing the reference image in each service node; a step (ii) wherein the defined reference image, boot kernel, activation module, and reduced operating system version are transferred into the service nodes; and a step (iii) wherein the transferred activation module is used in each service node in order to locally install the transferred reference image.
