  • Patent number: 8881125
    Abstract: Performance impact of a computing system component on a transient end-to-end system operation is estimated by profiling an overall characteristic for a transient end-to-end system operation, and simultaneously profiling a program code component for a second characteristic, thereby collecting a first pair of data points, repeating the operational period while introducing a known artificial delay into the program code component, and while profiling the overall performance characteristic for the system and for the program code component, thereby collecting pairs of data points for each repetition of the operational period for each of the artificial delays; curve fitting and analyzing intercepts of the collected data points to estimate the effect of the artificial delays in the program code component on the transient end-to-end system operation; and reporting the estimate correlated to potential optimal transient end-to-end system operation.

  • Patent number: 8266606
    Abstract: A mechanism is provided for increasing efficiency of tasks by observing the performance of generally equivalent code paths during execution of the task are disclosed. Embodiments involve a computer system with software, or hard-coded logic that includes reflexive code paths. The reflexive code paths may be identified by a software or hardware designer during the design of the computer system. For that particular computer system, however, one of the code paths may offer better performance characteristics so a monitor collects performance data during execution of the reflexive code paths and a code path selector selects the reflexive code with favorable performance characteristics. One embodiment improves the performance of memory allocation by selectively implementing a tunable, linear, memory allocation module in place of a default memory allocation module.

  • Patent number: 7979661
    Abstract: Methods, systems, and media to enhance memory overflow management by identifying a memory overflow condition associated with execution of a task and adjusting memory allocation for the task to attenuate the memory overflow condition are disclosed. In particular, embodiments reduce the impact of repetitious memory overflow conditions caused by a specific task by increasing the memory allocation for that task. The memory overflow may also be reported to a technical service provider to help the technical service provider identify and fix the code that is responsible for the memory overflow. Many embodiments monitor an extent of the overflow and determine an allocation correction term based upon the extent of the overflow. In some situations, application of a correction term to increase the memory allocation for the task may advantageously eliminate the cause of the memory overflow condition. In further situations, the impact of the memory overflow condition is attenuated.

  • Patent number: 7779223
    Abstract: Methods, systems, and media to enhance memory leakage management by identifying a suspect allocation pattern during execution of a task, which may be indicative of memory leakage and implementing measures to protect against memory leakage based upon the suspect allocation pattern, are disclosed. More specifically, embodiments may detect a suspect allocation pattern by monitoring memory allocations and deallocations for tasks. The pattern of memory allocations and deallocations may then be analyzed to determine whether a suspect allocation pattern exists. For instance, the memory allocations and deallocations may be compared to determine whether there is an increasing net residual allocation left by the task after it has reached a quiescent runtime state. In some embodiments, a suspect allocation pattern exists if the total memory allocation for a task continues to rise after a pre-determined time period.
