摘要

分析工具对于理解并行应用程序的行为和帮助优化过程至关重要。但是，像Perf这样的工具会生成大量的数据。这样，它们需要大量的存储空间，这也使对大量数据的推理变得复杂。因此，我们提出了VisPerf:一个用于Perf数据的工具链和交互式可视化仪表板。VisPerf工具链分析应用程序并对数据进行预处理，将所需的存储空间减少了约50倍。此外，我们使用可视化仪表板快速了解不同事件的性能，并可视化实际应用程序的特定线程和功能。

Performance Data Visualization of Linux Events on Multicores

Profiling tools are essential to understand the behavior of parallel applications and assist in the optimization process. However, tools such as Perf generate a large amount of data. This way, they require significant storage space, which also complicates reasoning about this large volume of data. Therefore, we propose VisPerf: a tool-chain and an interactive visualization dashboard for Perf data. The VisPerf tool-chain profiles the application and pre-processes the data, reducing the storage space required by about 50 times. Moreover, we used the visualization dashboard to quickly understand the performance of different events and visualize specific threads and functions of a real-world application.
