The invention relates in particular to optimizing memory access in a microprocessor including several logic cores upon the resumption of executing a main application, and enabling the simultaneous execution of at least two processes in an environment including a hierarchically organized shared memory including a top portion and a bottom portion, a datum being copied from the bottom portion to the top portion for processing by the application. The computer is adapted to interrupt the execution of the main application. Upon an interruption in the execution of said application, a reference to a datum stored in a top portion of the memory is stored, wherein said datum must be used in order to enable the execution of the application. After programming a resumption of the execution of the application and before the resumption thereof, said datum is accessed in a bottom portion of the memory in accordance with the reference to be stored in a top portion of the memory.

The invention relates to a process for assignment, by an addressing server for a network, of a network address to a terminal network-element connected to one of the connection ports of one of the interconnection network-elements of said network, comprising: transmission of a network address request by said terminal network-element to said interconnection network-element, the determination by said interconnection network-element of a location of said terminal network-element where said location combines a topological identifier for said interconnection network-element with at least one identifier for said connection port, the transmission by said interconnection network-element to said addressing server of said request with said location, assignment by said addressing server to said terminal network-element of said network address based on said location.

A method designed to configure an IT system having at least one computing core for executing instruction threads, in which each computing core is capable of executing at least two instruction threads at a time in an interlaced manner, and an operating system, being executed on the IT system, capable of providing instruction threads to each computing core. The method includes a step of configuring the operating system being executed in a mode in which it provides each computing core with a maximum of one instruction thread at a time.
