    • A method of acquiring software profile information of a target software application includes Monitoring an application program for system calls, detecting a system call of interest to the user, acquiring stack information, and processing the call stack information to produce statistical information concerning function calls. The call stack information includes program counter and other information which is derived from the target application as well as operating system. The call stack information may be recorded. The statistical information includes statistics concerning the number of samples that any one function call is at a top of the call stack information, the number of samples that a series of functions calls are included in the call stack information, and the number of samples that a set of function calls are at the top of the call stack information.

    • A method of acquiring software profile information of a target software application includes receiving a programmed interrupt while executing an application in a computer system, servicing the interrupt such that call stack information is acquired and processing the call stack information to produce statistical information concerning function calls. The call stack information includes program counter and other information which is derived from the target application as well as operating system. Some or all of the call stack information may be recorded. The statistical information includes statistics concerning the number of samples wherein a series of functions calls are included in the call stack information and the number of samples wherein a set of function calls are at the top of the call stack information.
    • 获取目标软件应用的软件简档信息的方法包括:在计算机系统中执行应用程序时接收编程的中断,为中断提供服务,从而获取调用堆栈信息,并处理调用堆栈信息以产生关于功能调用的统计信息。 调用堆栈信息包括从目标应用程序以及操作系统导出的程序计数器和其他信息。 可以记录部分或全部呼叫栈信息。 统计信息包括关于调用堆栈信息中包括一系列函数调用的样本数的统计信息,以及其中一组函数调用位于调用堆栈信息的顶部的样本数。

    • The present invention provides a method and system for capturing the call stack of a currently-running thread at the time a profiler interrupt occurs. The thread context of the thread is determined before a full push of the thread context is performed by the CPU architecture. The hardware state at the time of the interrupt is used to aid in determining which portions of memory to search for portions of the thread context. Based on the hardware state and the software state of the thread at the time of the interrupt the thread context is captured. Code may also be injected into a thread to capture a thread's call stack. The state of the thread is altered to induce the thread to invoke the kernel's call stack API itself, using its own context.
    • 本发明提供一种在分析器中断发生时捕获当前运行的线程的调用堆栈的方法和系统。 在线程上下文由CPU架构执行完全推送之前确定线程的线程上下文。 中断时的硬件状态用于帮助确定存储器的哪些部分来搜索线程上下文的部分。 基于硬件状态和中断时线程的软件状态,捕获线程上下文。 代码也可以被注入线程以捕获线程的调用堆栈。 改变线程的状态,以引导线程使用自己的上下文调用内核的调用栈API本身。

    • Systems and methods are described for replicating virtual memory translation from a target computer on a host computer, and debugging a fault that occurred on the target computer on the host computer. The described techniques are utilized on a target computer having a processor that has halted execution. Virtual to physical address translation data from the target computer is transferred to the host computer. The host computer utilizes the virtual to physical address translation data to access data pointed by virtual memory addresses that were used by the target computer, and then debugs a fault by accessing the data by reading the physical memory addresson the host computer. After the virtual to physical memory address translation data have been acquired, they can be cached at the host computer.

    • The present invention is a portable fire suppression apparatus. The fire suppression apparatus comprises a conduit with an open end and a closed end. In some embodiments of this invention the conduit may be a combination of several similar conduits connected with couplings with the last conduit having a closed end. The conduit has a plurality of apertures disposed upon its length at periodic intervals. When a fire suppression medium is forced throughout the conduit, the medium streams from each aperture and drenches the surrounding area and provides air borne spark suppression capability. In the preferred embodiment, this apparatus also includes a means for stabilizing the conduit against rotation while high pressure medium is forced through.
