[Performance] EPCTX file check doesn't happen for default model path #26294
Description
Describe the issue
The check if an Epctx file alreay exists, is carried out at the beginning of session creation even before graph_partitioning is called to fail early when session_options.epctx_file_path key is set.
As per this PR :
8705c68#r167792340
The check is not happening for default model paths. If epctx file path is not explicitly set then EP compile happens and failure for a exisiting epctx file is thrown in dump epctx model.
@adrianlizarraga I have added the comments part of the PR as well
To reproduce
onnxruntime_perf_test.exe -v -m times -r 1 -C "ep.context_enable|1 ep.context_embed_mode|0" -i "device_type|CPU" <path_to_model>
During first run epctx.onnx model will be generated.
When the same command is run again, the process should fail early that epctx.onnx model exists.
