Abstract: 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.

Abstract: In this method for controlling a server cluster, the cluster Including a plurality of nodes, automated agents measure the change in at least one metric quantifying the use of the nodes for the execution of an application, the agents determine, for each node, by measuring the metric, whether a change of phase has taken place in the executed application, and cause a change of the operation of the node if necessary; at regular intervals, an automated coordinator aggregates the metric measurements and the changes of operation of the nodes that have taken place and, on the basis of the aggregated measurements, the coordinator sends instructions to at least one of the agents.

Abstract: This data-processing device includes a unit for processing data, a storage memory and a buffer-memory device configured to contain a first group of data relative to a first context and exchange data between the processing unit and the first group of data. The buffer-memory device is further configured to contain a second group of data relative to a second context and, upon reception of a context-switching instruction, exchange data between the processing unit and the second group of data, in place of the first group of data. The data-processing device further includes a context-switching device configured to emit the context-switching instruction, select a group of data recorded in the storage memory, copy the first group of data to the storage memory and copy the selected group of data to the buffer-memory device.

Abstract: For the management of a file system for accessing data in a storage system in which the data are stored physically in a unique manner, a first storage environment associated with a first access performance level is mounted, from a first mount point. Moreover, at least one second storage environment, different from the first storage environment, and associated with a second access performance level is mounted, from a second mount point and with total or partial overlay of data with respect to the first storage environment. The data physically stored in a unique manner in the storage system is accessed, either via the first mount point or via the second mount point, as a function of a data use case.
