摘要： A method, an apparatus, and a computer program product in a data processing system are presented for using hardware assistance for gathering performance information that significantly reduces the overhead in gathering such information. Performance indicators are associated with instructions or memory locations, and processing of the performance indicators enables counting of events associated with execution of those instructions or events associated with accesses to those memory locations. The performance information that has been dynamically gathered from the assisting hardware is available to the software application during runtime in order to autonomically affect the behavior of the software application, particularly to enhance its performance. For example, the counted events may be used to autonomically improve the performance of the execution of an application by relocating code segments and data areas.

摘要： An apparatus and method are provided for the dynamic instrumentation of code to minimize system perturbation during tracing of the execution of the code. With the apparatus and method, “hot spots” in the execution of the code are dynamically determined during tracing of the execution of the code. These “hot spots” are dynamically instrumented, i.e. an event hook is inserted, to cause control to be passed to a handler that determines a caller of the “hot spot” method. The method that called the “hot spot” method, or “caller” method, is identified from a call stack and is dynamically instrumented for an appropriate metric so that the next time the calling method is executed, the dynamically inserted hooks are executed. The execution of the hooks in the caller method is continued for a predetermined period, e.g., number of invocations, to get an understanding of the caller method's characteristics. A list of callers of instrumented methods is maintained and used to determine one or more calling methods of the instrumented caller method. One or more of these calling methods may be instrumented and the hooks inserted in the instrumented caller method (called by the one or more calling methods), are removed. In this way, the call graph of the hot spots of a program execution is “walked up” and characterized over time.
摘要翻译：提供了一种用于在代码执行跟踪期间对代码进行动态检测以最小化系统扰动的装置和方法。利用该装置和方法，在代码执行的跟踪期间动态地确定代码执行中的“热点”。这些“热点”被动态地装配，即插入事件钩子，以使得控制被传递给确定呼叫者“热点”方法的处理程序。称为“热点”方法或“呼叫者”方法的方法是从调用堆栈中识别的，并为适当的度量进行动态检测，以便下次执行调用方法时，会执行动态插入的钩子。调用方法中的挂钩的执行持续一段预定时间，例如调用次数，以便了解呼叫者方法的特征。维护检测方法的呼叫者列表，并用于确定被调用呼叫者方法的一个或多个呼叫方法。可以对这些调用方法中的一个或多个进行检测，并且删除插入到被调用的调用方法中的钩子（由一个或多个调用方法调用）。以这种方式，程序执行的热点的调用图被“走过”并且随着时间的推移而被表征。

摘要： A method, apparatus, and computer instructions in a data processing system for processing instructions are provided. Instructions are received at a processor in the data processing system. If a selected indicator is associated with the instruction, counting of each event associated with the execution of the instruction is enabled. In some embodiments, when it is determined that a cache line is being falsely shared using the performance indicators and counters, an interrupt may be generated and sent to a performance monitoring application. An interrupt handler of the performance monitoring application will recognize this interrupt as indicating false sharing of a cache line. Rather than reloading the cache line in a normal fashion, the data or instructions being accessed may be written to a separate area of cache or memory area dedicated to false cache line sharing data. The code may then be modified by inserting a pointer to this new area of cache or memory. Thus, when the code again attempts to access this area of the cache, the access is redirected to the new cache or memory area rather than to the previous area of the cache that was subject to false sharing. In this way, reloads of the cache line may be avoided.

摘要： A method, apparatus, and computer instructions in a data processing system for processing instructions are provided. Instructions are received at a processor in the data processing system. If a selected indicator is associated with the instruction, counting of each event associated with the execution of the instruction is enabled. In some embodiments, the performance indicators may be utilized to obtain information regarding the nature of the cache hits and reloads of cache lines within the instruction or data cache. These embodiments may be used to determine whether processors of a multiprocessor system, such as a symmetric multiprocessor (SMP) system, are truly sharing a cache line or if there is false sharing of a cache line. This determination may then be used as a means for determining how to better store the instructions/data of the cache line to prevent false sharing of the cache line.

摘要： A system and method for monitoring software locks is presented. Metric data collection is invoked only when thin lock contention arises in a computer system's application layer. Instrumentation in a computer system's middleware layer tracks time-based metric information such as a waiting time for an application to acquire a lock. Instrumentation tracks garbage collection events and removes garbage collection time durations from time-based metric data as to not distort time-based metric data. Instrumentation also tracks quantity-based events such as the number of applications that request a particular lock. An instrumentation user may retrieve metric data for computer system performance analysis.

摘要： An apparatus and method for cataloging symbolic data for use in performance analysis of computer programs is provided. The apparatus and method stores symbolic data for loaded modules during or shortly after a performance trace and utilizes the stored symbolic data when performing a performance analysis at a later time. A merged symbol file is generated for a computer program, or application, under trace. The merged symbol file contains information useful in performing symbolic resolution of address information in trace files for each instance of a module. During post processing of the trace information generated by a performance trace of a computer program, symbolic information stored in the merged symbol file is compared to the trace information stored in the trace file. The correct symbolic information in the merged symbol file for loaded modules is identified based a number of validating criteria. The correct symbolic information for the loaded modules may then be stored as an indexed database that is used to resolve address information into corresponding symbolic information when providing the trace information to a display for use by a user.

摘要： A low-overhead performance measurement of an application executing in a data processing system is provided in order to generate per-thread performance information in a multithreaded environment. While a first set of events is being monitored for a particular thread as a first metric, events that may indirectly cause inaccuracies in the first metric, such as thread switches, are also monitored as a second metric. The presence of a positive value for the second metric is then used to determine that the first metric is inaccurate or unreliable, after which the first metric may be discarded; otherwise, the first metric is considered accurate. For example, the first metric may then be considered a thread-relative metric as it has been observed during a time period in which no thread switch events or interrupt events would have caused the first metric to become inaccurate during the execution of a particular thread.
