[MacOS] legacy_async_memcpy test appears to hang ( homebrew build, gcc-10) #6
Comments
@bjoo I'm momentarily Mac-challenged, would it be too much to ask for a few extra details e.g. machine configuration and a stack-trace (across all threads) for the live-locked state? Thank you. Cheers! |
No probs, I’ll get this as soon as I can. :)

This legacy_async_memcpy test continues to hang. (MacOS Ventura 13.2.1, brew gcc 12.2.0, M1 Max aarch64) Open Files & Ports: Process sample attached showing two threads spinning in _pthread_cond_wait and vectorAdd() |
Contrary to the HIP-CPU macOS install instructions I did not install Intel tbb. (figuring gcc has supported STL parallel algorithms for several major versions now) |
The legacy_memcpy test hangs in similar way. Process sample attached. Sample of legacy_tests legacy_memcpy.txt We can disable these two tests and all others pass.
Why are nearly all test names prefixed with "legacy_" ? |
I did
I'm not seeing any logic in |
I patched line 48 of /CMakeLists.txt to naively force enable TBB. I find the built tests are linked to TBB, but the same legacy_memcpy and legacy_async_memcpy tests hang.

Ctest test 23:
legacy_async_memcpy
appears to hang on MacOS when built with gcc-10 from homebrew -- MacOS Catalina (10.15.7) - similar behaviour is seen on MacOS CI where this test times out along with test27: legacy_memcpy
