  • Patent number: 9792148
    Abstract: Controlling access to at least one memory location by a transaction is provided in a multi-processor transactional execution environment. Included is: tracking execution progress of a transaction, the execution progress being a metric of work performed for the transaction which includes at least one of instructions processed or cycles elapsed; based on encountering a conflict with another process for a memory location, comparing execution process of the transaction and execution progress of the other process; and deciding whether to continue the transaction based on the comparing. For instance, based on the execution progress of the transaction being greater than the execution progress of the other process, the transaction is continued, and based on the execution progress of the transaction being less that the execution progress of the other process, then the transaction is aborted.

  • Patent number: 9785473
    Abstract: Configurable per-task state counters for processing cores in multi-tasking processing systems are disclosed along with related methods. In part, the disclosed embodiments include a work scheduler and a plurality of processing cores. The work scheduler assigns tasks to the processing cores, and the processing cores concurrently process multiple assigned tasks using a plurality of processing states. Further, task state counters are provided for each assigned task, and these task state counters are incremented for each cycle that the task stays within selected processing states to generate per-task state count values for the assigned tasks. These per-task state count values are reported back to the work scheduler when processing for the task ends. The work scheduler can then use one or more of the per-task state count values to adjust how new tasks are assigned to the processing cores.

  • Patent number: 9772886
    Abstract: A method for tuning workflow settings in a distributed computing workflow comprising sequential interdependent jobs includes pairing a terminal stage of a first job and a leading stage of a second, sequential job to form an optimization pair, in which data segments output by the terminal stage of the first job comprises data input for the leading stage of the second job. The performance of the optimization pair is tuned by determining, with a computational processor, an estimated minimum execution time for the optimization pair and increasing the minimum execution time to generate an increased execution time. The method further includes calculating a minimum number of data segments that still permit execution of the optimization pair within the increased execution time.

  • Patent number: 9733980
    Abstract: Techniques are described for managing virtual machines using input/output (I/O) device logging. For example, a system bus or other interface to a device may be monitored for traffic data elements. The traffic data elements may include, for example, transaction layer packets (TLPs) for communication across a PCI Express interface, or TCP/IP packets for communication over a network. These traffic data elements may be logged in an I/O device logging buffer. The I/O device logging buffer can then be used to ensure that all memory relating to a virtual machine is copied when transferring the virtual machine to another computing device. In addition, the I/O device logging buffer can be used to stop a virtual machine without waiting for the virtual machine to complete I/O processing.

  • Patent number: 9734042
    Abstract: During execution of a computer program, mouse movements, keyboard inputs, and screen snapshots are recorded and stored in one or more files as a test flow. Next, selected recorded keyboard inputs are replaced with user-specified variable parameters to generate a keyboard testing input, each of the parameters corresponding to a plurality of possible keyboard inputs. Execution is triggered of the test flow including the recorded mouse movements, the recorded screenshots, and the keyboard testing input. If the initially displayed screen is not equivalent to the first screen indicted in the test flow as being the start of the test, the test flow is stopped. Otherwise, the test flow is executed utilizing a random selection of the plurality of possible keyboard inputs of the keyboard testing input. At least one output is provided for the execution of the test flow.

  • Patent number: 9712404
    Abstract: In performance estimation when the configuration of a computer system is changed, the influence, on performance, of a temporary increase in load to a computer system due to reallocation of a process request allocated to a degenerated server to another server as a result of server degeneration is taken into consideration. In an embodiment, an information processing device which evaluates the performance of the computer system estimates the performance of the computer system when operation of a server included in the computer system is stopped based on the throughput required for the server at the time of operation stop and outputs the estimated performance of the computer system.

  • Patent number: 9703572
    Abstract: The detection of whether a local application is managed by a management service is described. In one example, depending upon whether an installation token includes a unique token value, detection logic can determine whether an application is managed or unmanaged based on additional factors. The additional factors include whether a keychain installation token includes a unique token value, the value of the keychain installation token, and a value of a launched flag for the application. Various combinations of those factors and the identification of either a managed or unmanaged status for the application are described. Using the concepts described herein, an unmanaged application can proceed to execute with limited functionality, present a notification that it should be reinstalled by the management service, stop executing, or take other measures.
