cmrt_dump.txt generated

[zjin-lcf]

I find that cmrt_dump.txt is generated after running a SYCL program with CUDA support. The file is empty.

@zjin-lcf, am I right the request here is to explain why that file is being generated and moreover, avoid generating it, right?

[zjin-lcf]

Yes. You are right. Thanks.

Sorry. Could the developers of CM explain when this file is generated ?

I bet it was caused by ESIMD emulator, which build was enabled for a few days. @dongkyunahn-intel, does it seem like a possible cause?
@zjin-lcf, could you make a clean build of a new compiler and check if this file is still generated, please?

@AlexeySachkov, I don't think it's related to CUDA.

[zjin-lcf]

Yes, I built the compiler with CUDA support today.

configure.py --no-werror --cuda --shared-libs -t release -o build_dir
compile.py -o build_dir 

The file is generated. Can you reproduce that ? Thanks.

cmrt_dump.txt is generated by CM - https://github.com/intel/cm-cpu-emulation/blob/3c9eb58b06b72d28de3015d23243f0fa594cdb31/libcmrt/cm_statistics.cpp#L95.

However, ESIMD_EMULATOR using CM is enabled only with --enable-esimd-emulator option in origin/sycl branch (#5366). I would suggest pulling up-to-date origin/sycl branch to local working branch and doing clean build after cleaning $BUILD directory. (rm -rf $BUILD/*)

I did clean build using origin/sycl without ESIMD_EMULATOR support. I cannot find any file related to CM in $BUILD/install directory.

Thank you for your suggestions!

Hi. I'll get rid of it in the next CM EMU opensource release.

[zjin-lcf]

Okay.
