Building with high parallelism and CUDA support results in sporadic build failures

[amarshall]

Building with 48 threads, of 50 sequential builds, 19 failed (38% failure rate). Am building via nixpkgs drv, but I don’t see any reason why it’s specific to that build environment. Building without CUDA saw no failures in 50 runs.

My guess is there’s an implicit dependency somewhere, I spent a brief bit trying to find it but did not (I’m not very proficient with CMake).

I have seen at least two different failures:

Filed as internal issue #OSD-426

[davidgyu]

Interesting. We haven't seen that before.
Can you tell us more about your system configuration: OS, Compiler, GPU, Driver version, CUDA version?

[amarshall]

Hi! Thanks for the reply.

• OS is NixOS @ NixOS/nixpkgs@9ca7856 (Linux Kernel 6.1)
• Opensubdiv src @ v3.5.0
• GCC 12.3.0 (note that -DCUDA_HOST_COMPILER is different), CMake 3.26.4
• CUDA toolkit 11.8.0
• CPU is AMD 3960X (24-core, 48-threads), 192 GB RAM
• GPU is 3080 Ti with driver 535.86.05 (however I think this should not matter, as I don’t believe the GPU is used during build)

[davidgyu]

Thanks for the additional information!

[bonsairobo]

I just hit this failure when building nixpkgs. The build succeeded on retry. Just making it known that the workaround is not a silver bullet.

[jfpanisset]

I see the same issue when building in a Rocky 8.10 container on a 40 core system. Arbitrarily limiting build threads to 4 seems to allow CUDA builds to work. Happy to test any proposed changes to build scripts since I can reproduce at will.

[MultiCoreNop]

I just hit the same opensubdiv error (32 core system, NixOS, blender dependency). Also stumbled over NixOS/nixpkgs#69228 which is the same error I saw and was supposedly fixed by using unstable. But, maybe it was just the "retry" that did it. At least, a retry as suggested by @bonsairobo fixed it for me as well.

[SuperSandro2000]

In NixOS we limited the core count to 16 and I just hit it there, too. Going to file a PR to lower it even more. Would be appreciated if the dependencies could be improved in the CMakeFiles.

[davidgyu]

I'll take another look at the dependencies. I regularly run 40+ job builds on our Alma Linux workstations, but sounds like there's something we've missed.
