Profiling PTOAS-generated kernels for MindStudio Insight requires using the msprof op simulator to collect execution data, resolving exact mangled kernel symbols, and exporting trace.json files. This workflow specifically supports WSL-based Ascend A3 dav_2201 development environments.

Kernel symbol resolution locates the compiled kernel shared library and identifies the exact mangled symbol required by the simulator. Without correct symbol resolution, the Ascend msprof op simulator cannot target the PTOAS-generated kernel for profiling.

Yes, the msprof op simulator supports WSL-based Ascend A3 dav_2201 workflows for kernel profiling. It requires a configured Ascend CANN environment, a built application and kernel library, and properly located simulator dump metadata to successfully collect and export trace data.

Building a host runner for PTOAS kernel profiling involves configuring and compiling an executable that launches the target kernel and references the generated source. This executable is necessary to execute the kernel within the Ascend operation simulator environment for data collection.

Trace export fails with missing program-counter metadata when simulator dump paths are incorrectly configured or metadata files are misplaced. Troubleshooting involves verifying dump path configurations and ensuring the simulator collection output is accessible before exporting to MindStudio Insight.

Analyzing PTO kernel performance with MindStudio Insight is best achieved by profiling the kernel with the Ascend op simulator and exporting the collected data into trace.json and visualize_data.bin files. These exported files can then be loaded directly into MindStudio Insight for visualization.
