摘要： This invention relates to a management method, more particularly by logging and replay, for software operations performed during the execution of an application process executed on a computer. This method applies in particular to internal operations sending a result datum to the managed process, and comprises the following steps: carrying out a deterministic software processing, termed prediction function (FH), based on the state of a managed process or of the application (AOP, ASB), to provide a predicted result (RP) for said operation; comparative test to establish whether the value of the predicted result (RP) corresponds or does not correspond to the value of the actual result (DR, RRJ); performance of a complementary management phase (CH, DH) of said managed operation, this complementary management depending on the result of the preceding test.

摘要： Mechanisms for managing task events during the scheduling period of a task executing on a processor. Only events of specific portions of the scheduling period are logged, wherein a first shared resource access has been granted for the task, this portion of the scheduling period involving gathering all the non-deterministic events which cannot be replayed by simple task re-execution. Other independent non-deterministic event records are still logged as usual when they occur out of the portion of the scheduling period for which a record has been created. This limits the number of logged events during a recording session of an application and limits the frequency of events to transmit from the production machine to the replay machine.

摘要： A method is provided which includes: facilitating intercepting a system call in user space by setting up signal handler code for executing operations related to the system call, and performing in the executing process, before execution of the system call, a SELF PTRACE request which sets system and self trace flags in the operating system kernel, wherein the self trace flag facilitates self-notifying the executing process whenever the executing process executes the system call; and intercepting the system call, including: verifying by the kernel that the system and self trace flags are set; saving and sending a signal to the signal handler conveying system call information to the user space; starting execution in user space of the signal handler; and at the end of signal handler execution, re-starting execution of the executing process, while providing system call return information to code of the executing process making the system call.

摘要： This invention relates to a method for replaying, from a log file, internal events within a process belonging to a software application in a network. This method comprising the following steps: executing at least one replay instruction by the target process, initiating a replayed operation (EVI) that returns, to this target process (PB1), at least one result datum obtained (RRJ) by this replayed operation; performing, by a software agent (PRI) external to the restart process, a forcing process (7) comprising a forcing operation upon the target process, instead and in place of the replay result datum (RRJ), of a forced datum, (RLi), extracted from logging data. Advantageously, the target process (PB1) executes the replay instruction of its own initiative from its executable file (EXE; FIG. 7).

摘要： This invention relates to a method for the transmission of logging data, within a cluster of computers, enabling all or part of the events constituting the running of a user process to be memorized or reproduced. The method applies in particular to the logging data representing the internal events of this process. When the functioning of the primary user memory space is managed by system software managing first software and hardware communication resources (OPsock, OPM) to enable an exchange of data with another node (SB), this method comprises transmitting the logging data from the first user memory space (OPU) to second software and hardware communication resources (HSI) in order to transmit them to this secondary node at a rhythm globally equivalent to that of the execution of the logged process.

摘要： A method, computer program and system for controlling accesses to memory by threads created by a process executing on a multiprocessor computer. A page table structure is allocated for each new thread and copied from the existing threads. The page access is controlled by a present bit and a writable bit. Upon a page fault the access is provided to one thread. The kernel handles the new page entry creation process and set the page present bits to zero which creates page faults. In a second embodiment, two page table structures are created, one for one thread having access to the address space and the other page table structure shared by all the other threads not having access to the address space.

摘要： A method for carrying out a connection migration in a multicomputing architecture (cluster), from a first node which is called a primary node or operation node, including a first computer of the cluster on which an initial software application is run, towards at lest one secondary node including another computer of the cluster. The method implements a virtual network address which is carried by the first computer and transferred to the other computer, the virtual network address being embodied in the form of a dialogue link between the cluster and client computers connected thereto and associated with the software application. The associated connections can, for example be associated with a software application which is replicated in another computer in such a way that the initial application service is switched to the replica thereof.
