摘要： Managing processes in a computing system comprising one or more cores includes generating an object in an operating system running on at least one core. A reference to the object is distributed to each of at least one and fewer than all of a plurality of processes to be executed on the at least one core. The operating system controls access to a resource such that processes to which the reference to the object was distributed have access to the resource and processes to which the reference to the object was not distributed do not have access to the resource.

摘要： A system and method for managing the environment of software processes in a computer system. A computer system comprises a processor and at least one process environment comprising one or more environment variables. The processor executes one or more processes, intercepts the launch of a process, sets at least one environment variable to a first value, and continues the launch of the process. Setting the environment variable may enable a profiler process. The processor may set at least one environment variable for the process to a value which is chosen irrespective of a value of the environment variable of a parent process of the process. Further, the processor may set at least one environment variable for the process to a default value if a data repository does not contain an entry that has an identification which corresponds to the process.

摘要： Managing data in a computing system comprising a plurality of cores includes assigning home cache locations of at least a first type of data associated with a first process executing on a first core to respective caches of one or more of the plurality of cores. Cores other than a home core, whose cache includes a home cache location for given cached data, access the given cached data by communicating with the home core. Home cache locations of at least a second type of data associated with the first process are assigned to a local cache of the first core. In response to migrating the first process to execute on a second core, home cache locations of the second type of data associated with the first process are re-assigned to a local cache of the second core.

摘要： Methods and systems are provided for internal monitoring of applications. A distributed management framework may comprise a plurality of applications and application servers, wherein each of the applications is configured to make function calls to standard programming functions. The function calls to the standard programming functions are intercepted. The function calls are routed to alternative implementations of the standard programming functions, and the alternative implementations are used to collect availability metrics for the plurality of applications. Manager threads may be used for internal monitoring of application execution. Applications may be modified with additional instructions to monitor program execution and automatically generate output comprising an execution history.

摘要： Managing processes in a computing system comprising one or more cores includes receiving a request for a first process on a first core to execute with at least one predetermined task of an operating system disabled on the first core. In response to the request, the operating system determines whether one or more potential errors in execution of one or more processes other than the first process executing on the first core would be caused by disabling the predetermined task on the first core. The operating system grants the request or rejects the request in response to determining whether one or more potential errors in execution of one or more processes other than the first process executing on the first core would be caused by disabling the predetermined task on the first core.

摘要： A method for determining changed code in a second program binary relative to a first or baseline program binary, where the second program is a different version of the first program, includes translating, responsive to symbol tables and/or control flow representations, machine addresses of both program binaries to symbols. The first and second program binaries are disassembled using the translated symbols. Differences between the two resulting disassemblies are determined, and a list of the differences is created. Differences between the program binaries can be determined by textually comparing the disassemblies, or alternatively, by determining the differences between the control flow representations of the programs. The list of differences can be presented to a user, or alternatively, can be passed to another process for further processing, such as test coverage analysis, code change analysis, or failure analysis, among other analyses. Analyzing changed code coverage includes marking code in the second program which is changed or different from the first program. The second program is then executed in a test environment, and code which is executed is marked as having been executed. Next, the second program is executed in a non-test environment, such as a production environment, and code which is executed in this second environment is marked accordingly. Finally, from the variously marked code, a list of changed code which have not executed in the test environment but have executed in the non-test environment is provided.

摘要： Managing processes in a computing system comprising one or more cores includes generating an object in an operating system running on at least one core. A reference to the object is distributed to each of at least one and fewer than all of a plurality of processes to be executed on the at least one core. The operating system controls access to a resource such that processes to which the reference to the object was distributed have access to the resource and processes to which the reference to the object was not distributed do not have access to the resource.
