Abstract
On a machine with non-uniform memory access distributed over several modules, each module includes one or more processors for executing tasks on a virtual or physical addressing space by effective addresses generating logical page numbers to which it is possible to make physical page numbers correspond in the memory by a correlation tale. The generation of a logical page number causes a first-level page-fault type exception when the logical page number is absent from the correlation table. The method includes a step for activating a function (Trace), following each first-level page-fault type exception, a trace function, which records the value of the effective address that has generated the logical page number that has caused the exception, the date when the exception is caused, an identifier of the task using the effective address, an identifier of the processor executing the task and the physical page number corresponding to the logical page number that has caused the exception.
