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： Disclosed is a method for replicating a software application in a multi-computer architecture (cluster). The software application is executed on a first computer of the cluster, which represents a primary or operation node, and is replicated on at least one other computer of the cluster, which represents a secondary node, including replication of the resources associated with the software application. The method includes streamlined updating of the replicated resources via a dynamic introspection mechanism supplying the structure of the application that is to be replicated and the dynamic graph of the implemented resources and dependencies.

摘要： This invention relates to a management method, more particularly by recording or external control, of software operations (EVI; FIGS. 8a, 8b) performed within the execution of an application process executed on a computer. This management applies in particular to the recording of operations in the form of logging data, or to a replay of operations according to a given execution corresponding to a running previously logged running. This method applies in particular to operations returning at least one result datum (DR, RRJ) to the managed process, and comprises the carrying out of at least one complementary management phase (GC) for said managed operation, this complementary management depending on the deterministic or non deterministic nature of said managed operation or of its result.

摘要： A multiprocess computer system comprises at least two processes (P1, P2, . . . Pi, . . . PN) connected by a network. Each process is executed by a piece of hardware equipped with an operating system. A process comprises at least a library software layer by which this operating system can access the programs for the activation of the communications protocols associated with the inputs/outputs; an intermediate layer comprising an inter-process communications process associated with a communications channel; a multiplexer encapsulated in the library multiplexing the communications channel of a process Pi with the communications channels of the other processes P1, P2, . . . PN, the communications channel between two processes Pi, Pk being activated by the multiplexers of the two processes, upon a request by one of them. It can be used especially for extensive communications among various computer processes through standard inputs/outputs. More particularly, it can be used for the applications-transparent implementation of complex services such as services pertaining to client/server mode, distributed and concurrent processing, data flow control, malfunction tolerance, supervision, reconfiguration and dynamic extension as well as the modeling of the systems architecture.

摘要： A method, and system for intercepting a system call performed by a process and for executing processing in relation with the intercepted system call from user space. The method comprises a first step for setting up, in the executing process, a signal handler performing processing in relation with an interception of a system call in the executing process upon reception of a specific signal. The executing process performs a ptrace system call with a new request, the self ptrace, which sets, in the task descriptor of the executing process, the system trace flag corresponding to the existing system trace ptrace request and set a new flag, the pt_self flag. When a system call is performed in the executing process, a new system call trace is executed testing if the pt_self flag is set. If the pt_self flag is set a specific signal is sent to the executing process itself and the handler which has been set up is executed in user space.
