CUPTI Activity API: 逻辑. API 描述：能够以异步方式 (asynchronous) 收集 (record) CUDA 程序中各种函数 (driver, runtime, kernel 等) 时间戳和附加信息. CUPTI Activity API 收集性能参数逻辑：维护一个类似队列性质的数据容器 Buffer，整体逻辑如 图2.

The NVIDIA CUDA Profiling Tools Interface (CUPTI), distributed as part of the CUDA Toolkit, is a library that enables the creation of profiling and tracing tools that target CUDA applications. CUPTI provides a set of APIs targeted at ISVs creating profilers and other performance optimization tools:

CUPTI API 和 Callback API 逻辑关系：CUPTI 包含一系列 APIs，主要分为 2 类：tracing (整个程序执行情况) 和 profiling (调查 kernel 内部执行情况)，tracing API 中又包含 2 种 API，Callback API 是其中之一 能够实现：获取 cuda 程序执行过程中函数时间戳或通用信息，收集信息最小 ...

2025年2月11日 · CUPTI, the CUDA Profiling Tools Interface, ensures seamless profiling compatibility for CUDA applications across various GPU architectures and CUDA driver versions. As part of the CUDA Toolkit, CUPTI adheres to CUDA Toolkit compatibility requirements with CUDA drivers, which includes support for Backward, Forward and Enhanced compatibilities.

CUDA Profiling Tools Interface （CUPTI） 是NVIDIA提供的一个动态库，用于创建针对CUDA应用程序的性能分析和追踪工具。它为独立软件开发商（ISV）开发性能优化工具提供了低开销且确定性的性能分析功能，能够深入了解CUDA应用程序在CPU和GPU上的行为。

2017年6月2日 · The CUDA Profiling Tools Interface (CUPTI) enables the creation of profiling and tracing tools that target CUDA applications. CUPTI provides four APIs: the Activity API, the Callback API, the Event API, and the Metric API. Using these APIs, you can develop profiling tools that give insight into the CPU and GPU behavior of CUDA applications.

The NVIDIA CUDA Profiling Tools Interface (CUPTI) provides performance analysis tools with detailed information about how applications are using the GPUs in a system. CUPTI provides two simple yet powerful mechanisms that allow performance analysis tools such as the NVIDIA Visual Profiler, TAU and Vampir Trace to understand the inner workings ...
