摘要： A method of providing a visualization of states of a process includes identifying a set of potential states that can occur during the process and a corresponding set of colors, with each color in the set of colors corresponding to one of the potential states. A fixed ordering is established for the set of colors. A timeline graph including a plurality of colored vertical bars is displayed. Each colored vertical bar corresponds to a time interval of the process and includes at least one color selected from the set of colors based on at least one state occurring during the time interval corresponding to the vertical bar. The plurality of colored vertical bars includes a set of multiple-color vertical bars that each include a plurality of colors appearing in a vertical order based on the fixed ordering.

摘要： The present invention extends to methods, systems, and computer program products for time-based navigation within resource utilization data. A computer system is configured to present resource utilization data representing performance of computer resources. The resource utilization data is displayed on a diagnostic data trace during the execution of the application. The user can select a desired time range and the resource utilization data within the time range will be displayed at other traces. The diagnostic data trace is still presented so that the user can understand the relation between the selected time range and the overall time length. Further, the user can modify the selected time range by change the extents of the selected time range using resizing tool. The resource utilization data within the modified selected time range, similarly, is also displayed along with the diagnostic data trace.

摘要： A thread execution analyzer analyzes blocking events of threads in a program using execution data and callstacks collected at the blocking events. The thread execution analyzer attempts to identify an application programming interface (API) responsible for each blocking event and provides blocking analysis information to a user. The blocking analysis information may be used by a developer of the program to understand the causes of blocking events that occur for threads of the program.

摘要： Normalizing time across machines in a distributed system. A method includes obtaining one or more points defining differences in time between machines in the distributed system. Using the points, a determination of one or more time measurement drifts between machines is made. The one or more time measurement drifts indicate changing differences in time over time. One or more traces are collected. Each trace includes one or more events. Each event is correlated to a time stamp from one of the machines in the distributed system. Using the one or more determined time measurement drifts, the time stamps are normalized.

摘要： An analysis and visualization depicts how an application is leveraging computer processor cores in time. The analysis and visualization enables a developer to readily identify the degree of concurrency exploited by an application at runtime. Information regarding processes or threads running on the processor cores over time is received, analyzed, and presented to indicate portions of processor cores that are used by the application, idle, or used by other processes in the system. The analysis and visualization can help a developer understand contention for processor resources, confirm the degree of concurrency, or identify serial regions of execution that might provide opportunities for exploiting parallelism.

摘要： The visualization of a storage access on a timeline that represents various disk access events, such as a storage read event, or a storage write event. The storage access timeline may be formulated using event data gathered regarding storage access events, such as storage read requests, or storage write requests. The timeline may be displayed in conjunction with non-storage events, such as thread events, process events, processor events, or such, in order to give a visual indication of what is causing the storage access events. There may even be a control for displaying an identification of the file being accessed for one or more of the storage access events. With a better understanding of correlation between storage access events and application operation, optimization of the application itself may be achieved to more efficiently interface with the storage medium.

摘要： Methods, systems, and media for reducing memory latency seen by processors by providing a measure of control over on-chip memory (OCM) management to software applications, implicitly and/or explicitly, via an operating system are contemplated. Many embodiments allow part of the OCM to be managed by software applications via an application program interface (API), and part managed by hardware. Thus, the software applications can provide guidance regarding address ranges to maintain close to the processor to reduce unnecessary latencies typically encountered when dependent upon cache controller policies. Several embodiments utilize a memory internal to the processor or on a processor node so the memory block used for this technique is referred to as OCM.

摘要： Methods and systems are disclosed for measuring performance event rates at a computer and reporting the performance event rates using timelines. A particular method tracks, for a time period, the occurrences of a particular event at a computer. Event rates corresponding to different time segments within the time period are calculated, and the time segments are assigned colors based on their associated event rates. The event rates are used to display a colored timeline for the time period, including displaying a colored timeline portion for each time segment in its associated color.

摘要： A system and method for improving hardware-controlled pre-fetching within a data processing system. A collection of address translation entries are pre-fetched and placed in an address translation cache. This translation pre-fetch mechanism cooperates with the data and/or instruction hardware-controlled pre-fetch mechanism to avoid stalls at page boundaries, which improves the latter's effectiveness at hiding memory latency.
