Abstract

This method of managing a personal event log specific to an operating activity executed on a multiple-cell computer platform comprises:

while an activity is saving an event, a step of recording the event in a common event log together with an identifier of the activity that is saving the event; and

prior to an activity consulting its personal event log, a step of reconstructing the personal event log from the common event log, said reconstruction step including an operation of selecting from the common event log only those events which are associated with the identifier of the activity in order to include those events in the personal event log reconstructed for said activity.

Claims

1. A method of managing a personal event log specific to an operating activity, the log containing events recorded by said operating activity while it is being executed on a perimeter of computer hardware resources configured on a multiple-cell computer platform, each operating activity containing at least one operating system suitable for managing the computer resources of the perimeter on which it is to be executed, and the multiple-cell computer platform having a plurality of distinct computer hardware resource perimeters suitable for being activated in succession or simultaneously on the platform, the method comprising:

while an activity is saving an event, a step of recording the event in a common event log together with an identifier of the activity that is saving the event; and

prior to an activity consulting its personal event log, a step of reconstructing the personal event log from the common event log, said reconstruction step including an operation of selecting from the common event log only those events which are associated with the identifier of the activity in order to include those events in the personal event log reconstructed for said activity.

2. A method according to claim 1, wherein the computer hardware resources of perimeters are capable of generating events, and the method further comprises a step of recording in the common event log an event that has been generated by a computer hardware resource together with an identifier of the resource that has caused the event, and wherein the step of reconstructing a personal event log specific to an activity further includes an operation of selecting from the common event log only those events which are associated with the identifier of a computer hardware resource contained in the perimeter on which said activity is being executed in order to include those events in the personal event log reconstructed for said activity.

3. A method according to claim 1, further comprising:

while an activity is saving an event, a step of recording in the common event log a scope attribute associated with said event and specifying the activities which are authorized to consult said event and/or the perimeters from which activities are authorized to consult said event, and wherein the step of reconstructing a personal event log specific to an activity further includes an operation of selecting from the common event log only those events which are associated with a scope attribute authorizing said event to be consulted by the activity being executed and/or from the perimeter on which said activity is being executed in order to include those events in the personal event log reconstructed for said activity.

4. A method according to claim 1, further comprising:

while an activity is sending an instruction to modify at least one event in its personal event log, a step of recording in a file said instruction in association with an identifier of the activity, which file is accessible by the activity from all of the perimeters of the platform; and

prior to an activity consulting its personal event log, a step of executing the modification instruction applied to the personal event log as reconstructed for said activity during the reconstruction step.

5. A system for managing a personal event log specific to an operating activity while it is being executed, the system comprising:

a multiple-cell computer platform;

a management tool suitable for defining computer hardware resource perimeters and for activating said perimeters on the platform simultaneously or in succession, each perimeter comprising one or more calculation cells; and

means for storing operating activities, each operating activity comprising at least one operating system suitable for managing the computer resources of the perimeter on which the activity is to be executed;

the system further comprising;

a memory containing a common event log suitable for storing the events recorded by all of the operating activities;

a module for recording events in the common event log, said events being generated by each operating activity and being associated with an identifier of the activity causing the event to be saved; and

a reconstruction module for reconstructing a personal event log specific to an operating activity from a common event log, the reconstruction module including a selection submodule for selecting from the common event log only those events which are associated with the identifier of said operating activity in order to include those activities in the personal event log reconstructed for said activity.

6. A system according to claim 5, wherein the personal event log specific to an operating activity contains events recorded by the computer hardware resources of the perimeter on which the activity is being executed, and the system further comprises a module for recording in the common event log an event generated by a computer hardware resource of the perimeter in association with an identifier of said resource, and wherein the module for reconstructing a personal event log specific to an activity further comprises a submodule for selecting from the common event log only those events which are associated with an identifier of a computer hardware resource contained in the perimeter on which said activity is being executed, in order to include those events in the personal event log reconstructed for said activity.

7. A system according to claim 5, further comprising a module for saving in the common event log a scope attribute associated with each event and specifying the activities which are authorized to consult said event and/or the perimeters from which the activities are authorized to consult said event, and wherein the module for reconstructing a personal event log specific to an activity further comprises a submodule for selecting from the common event log only those events which are associated with a scope attribute that authorizes said event to be consulted by the activity being executed and/or from the perimeter on which the activity is being executed in order to include those events in the personal event log reconstructed for said activity.

8. A system according to claim 5, further comprising:

a recording module for recording instructions to modify at least one event in the personal event log specific to an activity, said recording module being suitable for recording in the memory said modification instructions in association with an identifier of the activity that has generated the instruction; and

a module for executing modification instructions recorded by an activity in the memory, said modification instructions being applied to the personal event log reconstructed for said activity by the reconstruction module.

9. A memory for storing information for use in a system for managing a personal event log according to claim 5, the memory containing a common event log containing a list of events saved by a plurality of different operating activities, each of said events being associated with an identifier for the activity which saved it.

10. An information storage memory according to claim 9, wherein the common event log also contains a list of events saved by computer hardware resources contained in perimeters, each of said events being associated with an identifier of the computer hardware resource that saved it.

11. An information storage memory according to claim 9, wherein the common event log contains a scope attribute associated with each saved event, said scope attribute indicating which activities are authorized to consult said event and/or the perimeters from which activities are authorized to consult the event.
