HeteroSTA engine fails to load: undefined symbol DefWriter::write in timing_heterosta_cpp.so

[GO25XIP]

Environment

• OS: Linux (x86_64)
• Python: 3.9
• CUDA: 11.8
• Timing engine: HeteroSTA (timer_engine = "heterosta")

Steps to reproduce

1. Run DREAMPlace with HeteroSTA as the timing engine (e.g. set "timer_engine": "heterosta" in the JSON config).
2. The error occurs after the benchmark is read and when the Timer is being initialized.

Error message

Traceback (most recent call last): File ".../dreamplace/Timer.py", line 40, in init import dreamplace.ops.timing_heterosta.timing_hs as timing File ".../dreamplace/ops/timing_heterosta/timing_hs.py", line 5, in import dreamplace.ops.timing_heterosta.timing_heterosta_cpp as timing_hs_cpp ImportError: .../timing_heterosta_cpp.cpython-39-x86_64-linux-gnu.so: undefined symbol: ZNK10DreamPlace9DefWriter5writeERKSsS2_RKSt6vectorINS_4NodeESaIS4_EERKS3_IjSaIjEEPKiSE

The C++ mangled symbol demangles to DreamPlace::DefWriter::write(...) (const member function with parameters including std::string, std::vector<Node>, std::vector<unsigned>, etc.).

Possible cause

The timing_heterosta_cpp extension depends on DreamPlace::DefWriter::write at runtime, but that symbol is not defined in timing_heterosta_cpp.so and was not resolved during linking. This usually means the object or library that defines DefWriter was not linked when building the timing_heterosta extension.

Expected behavior

With HeteroSTA enabled, import dreamplace.ops.timing_heterosta.timing_heterosta_cpp should succeed without the above ImportError.

Happy to provide build steps or CMake/setup configuration if that would help.

Could you try to add ${CMAKE_CURRENT_SOURCE_DIR}/../place_io/src/DefWriter.cpp below ${CMAKE_CURRENT_SOURCE_DIR}/../place_io/src/BinMap.cpp
in DREAMPlace/dreamplace/ops/timing_heterosta/CMakeLists.txt?
Please tell me if it works for you because I can't reproduce this error on my machine.

I added DefWriter.cpp and BookshelfWriter.cpp in the CMkeLists.txt. The undefined symbol problem is never shown.

When I tried to run a test(superblue1 from iccad2015.hs), the DREAMPlace could still not be able to run successfully. Here is my log file, hope there would be some clues to be found.

Are you able to run if setting gpu in json to 0? Just want to troubleshoot if the problem comes from gpu-related components.

[GO25XIP]

Hi, I set "gpu" to 0 in superblue1.json, but there is no changes or improvements. DREAMPlace still stuck on Segmentation fault (core dumped).

FYI， when I pip installed the requirements, I specified the package versions:

• numpy==1.24.4
• scipy==1.10.1
• torch==2.0.1

Other than that, I used GCC 9.5 for compilation and set the ABI to 0.

Your log shows HeteroSTA seemed crashed when initializing the data structure (my guess). Are you able to run HeteroSTA standalone successfully if following its simple demo?
