Abstract
The invention relates to a process for allocating physical memory locations in a multiprocessor data processing system comprising a non-uniform access memory unit distributed among a plurality of modules. Software applications are linked to a set of predefined memory allocation rules. When there is no entry for a virtual address in an address correspondence table, there is a generation of a page fault, and the allocation of a location in physical memory is carried out in accordance with a predefined rule as a function of the profile of the application and of the page fault type. The memory may be organized into segments and the segments subdivided into virtual address ranges, with the ranges associated with a specific memory allocation policy. In the case where there is an entry for a virtual address in an address correspondence table, the policy of the segment prevails.
