  • Adaptive instrumentation runtime monitoring and analysis
    Patent number: 7587709
    Abstract: 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.

  • Statistical memory leak detection
    Publication number: 20050091646
    Abstract: A method of detecting memory leaks. The method of detecting memory leaks comprises, adaptively bursty tracing a program execution to track accesses to heap objects with low overhead and using this information identify stale heap objects, which are reported as leaks.
