摘要： A run time software test tool instruments a program to perform a low overhead profiling of the program's execution, which records the execution time of frequent acyclic control flow paths using hardware performance counters. An analysis of the profiling data is performed to identify those program paths that have significant variation in execution time across different dynamic traversals in the same program run. This variation (measured as the difference between the fastest execution of that path and slower executions) represents the potential speedup that potentially could be achieved if the paths were optimized (such as by the addition of simple pre-fetch optimizations) to do away with these variations. The variational paths are identified to the programmer to guide optimization.

摘要： A dynamic analysis tool uses anomaly detection to find heap-based bugs. In spite of the evolving nature of the heap, programs generally exhibit several of properties of their heap usage that remain stable. Periodically, during the execution of the program, the analysis tool computes a suite of metrics which are sensitive to the state of the heap. These metrics track heap behavior, and the stability of the heap reflects quantitatively in the values of these metrics. The ranges of stable metrics, obtained by running a program on a multiple input training set, are then treated as indicators of correct behavior, and are used in conjunction with an anomaly detector to find heap-based bugs.
摘要翻译：动态分析工具使用异常检测来查找基于堆的错误。尽管堆的性质不断发展，但程序通常表现出其堆使用的几个属性保持稳定。定期地，在执行程序期间，分析工具计算一组对堆的状态敏感的度量。这些度量跟踪堆行为，并且堆的稳定性在这些度量的值中定量地反映。然后将通过运行多输入训练集上的程序获得的稳定度量的范围视为正确行为的指标，并与异常检测器结合使用以查找基于堆的错误。

摘要： Techniques described herein provide low-overhead adaptive instrumentation runtime monitoring and analysis of software. A method of instrumenting a program to provide instrumentation data creates instrumentation versions comprising duplicate versions of original procedures in the program with instrumentation code for capturing instrumentation data, and adaptively decreases the sampling rate of the instrumented version of a procedure as the frequency of execution of the procedure increases. Additionally, the instrumentation methods can be used to build runtime tools that monitor the correctness of a program with very little overhead.

摘要： A system and method for determining where bottlenecks in a program's data accesses occur and providing information to a software developer as to why the bottlenecks occur and what may be done to correct them. A stream of data access references is analyzed to determine data access patterns (also called data access sequences). The stream is analyzed to find frequently repeated data access sequences (called hot data streams). Properties of the hot data streams are calculated and upon selection of a hot data stream are displayed in a development tool that associates lines of code with the hot data streams.

摘要： A system and method for analyzing data accesses to determine data accessing patterns is provided. Data address accesses are traced and transformed into Whole Program Data Accesses (WPDAs). WPDAs may then be used to discover higher-level data abstractions, such as hot data blocks. Hot data blocks provide information related to sequences of data addresses that are repeatedly accessed together. Hot data blocks may then be used to improve program performance.
