Abstract: A method and device for allocating computer resources of a cluster for carrying out at least one job controlled by the cluster is disclosed. In one aspect, the method includes determining the placement of the job from physical features of the job and from physical features and availability of the computer resources of at least one processing area of the cluster. The method further includes receiving energy state features of the computer resources of at least the processing area; determining a recommended placement of the at least one job by correlating the physical features of the job, the physical features, availability and energy state of the computer resources on the basis of predetermined rules; and deducing, from the predetermined recommended placement, a recommended allocation list of the computer resources for carrying out the job in the cluster.

Abstract: A method of remote monitoring and remote control of a cluster including nodes connected to a communication network of a first type, a relay node of the nodes including first and second network interfaces in accordance with first and second types of communication network respectively, the first and second types being distinct, some steps of the monitoring and control method being implemented in a remote computer linked to the relay node by a communication network of the second type, the method including receiving a packet via the first network interface; encapsulating the received data packet in a data frame in accordance with a protocol of the communication network of the second type; sending the data frame to the remote computer via the second network interface, the receiving of the data packet, the encapsulating of the data packet and the sending of the data frame being implemented in the relay node.

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.

Abstract: A screen copying method including the copying, in the form of an image file, of a portion of an image displayed on a screen where a user graphically selects the image portion, the copying of the selected image portion automatically resulting in: the copying of the pointer or pointers associated with the image portion along with the coordinates of the pointers in the image portion, the pointers respectively pointing to objects; and the maintaining of the respective links between the pointers and the coordinates so that, during a subsequent redisplay of the image portion on a screen, the graphical selection of a point corresponding to one of the coordinates by a user automatically activates the pointer corresponding to the coordinate of the selected point and brings up the object corresponding to the activated pointer.

Abstract: The method relates to the monitoring of at least one routing parameter for a cluster including nodes and switches, static communication links connecting nodes and switches. Each switch includes several output ports. After having selected at least one switch, a number of routes per port is calculated for each port of each switch selected, routes being defined during a routing step for each connecting one node to another. A mean number of routes per port is then calculated for the at least one selected switch. Each number of routes per port calculated is then compared with the mean number of routes per port calculated and, in response to this comparison, a potential imbalance of routing of the cluster is notified.

Abstract: A method for allocating, in order to carry out a calculation, at least one first resource of a plurality of interconnected resources, the first resource being connected to a first port of a switch, the method including acquiring a first weight of the first resource, the weight corresponding to the number of resources of the plurality of resources connected to the first port of the switch.

Abstract: A method of processing a message by a first interconnection device, the method including: recording a first database of processing rules in the first interconnection device, recording an identifier of a second interconnection device in the first interconnection device, and processing a communication in accordance with local processing rules of the first local database of rules and with remote processing rules obtained from a second interconnection device which is identified by the identifier of the second interconnection device.

Abstract: A method for monitoring the operation of an IT infrastructure including a plurality of calculation nodes, includes selecting calculation nodes for performing a calculation, performing the calculation via the selected calculation nodes, attributing, via the sequencer, a score to each one of the calculation nodes having participated in the calculation performed, with each score reflecting a difference between a measured operating parameter of the calculation node for which the score is attributed and a reference operating parameter of the calculation node for which the score is attributed, verifying the operation of the calculation nodes having participated in the calculation performed, the verification being carried out using scores attributed to the calculation nodes having participated in the calculation.

Abstract: A method of aiding the design of a data center is disclosed. In one aspect, the method refers to generating a list of components from a library that satisfy a defined list of needs.

Abstract: The saving of data in an information technology (IT) infrastructure offering activity resumption functions is disclosed. For these purposes, a saving system is provided with at least one first and one second sets of data storage and at least one first and one second memory controllers associated with the first and second data storage, respectively. The saving system is furthermore provided with a microcontroller configured to duplicate a stream of commands and of data destined for the first memory controller to the second memory controller in a mode of normal use allowing a local replication of data in the second set of data storage and to address a distinct stream of commands and of data to each of the first and second memory controllers in a mode of remote replication.
