摘要
HP Caliper是一个用于构建动态仪器工具的框架,它允许您使用仪器探头实时更改程序指令。它为构建性能分析工具提供了一个通用框架,可以将硬件支持的性能测量单元(PMU)采样与动态仪器集成在一起。本文描述了Caliper的体系结构、公共接口和动态检测算法。
HP Caliper: a framework for performance analysis tools
HP Caliper, a framework for building dynamic instrumentation tools, lets you change program instructions on-the-fly with instrumentation probes. It offers a common framework for building performance analysis tools that can integrate hardware-supported performance measurement unit (PMU) sampling with dynamic instrumentation. This article describes Caliper's architecture, its public interfaces and its dynamic instrumentation algorithm.
