Segmentation fault during _bool_op in multiprocessing environment #880

Open ReubenVandezande opened 3 years ago

ReubenVandezande commented 3 years ago

While using cadquery in multiprocessing environments (ie. multiprocessing and MPI), I've noted a significant number of segfaults during the _bool_op routine. I generate a number of geometries in my script and see segfaults by around 1,000-10,000 generated geometries. Looking at the backtrace, I believe this issue is caused by the hard-coded op.SetRunParallel(True) in the _bool_op method.

I've been able to successfully generate ~1,000,000 geometries without segfault after manually setting this to op.SetRunParallel(False).

To Reproduce

I cannot reproduce the issue on command; this seems to be environment/geometry dependent and I can't post the full script here as it's quite large (modeling some complex systems). I can include a simplified version that communicates the idea of the offending script, but this example script doesn't segfault.

import cadquery as cq
from multiprocessing import Pool

def main():
    # Run the below function outside the pool to ensure it works correctly
    # generate()

    with Pool(5) as pool:
        while True:
            attempts = []
            for _ in range(1000):
                attempts.append(pool.apply_async(generate))

            [attempt.get() for attempt in attempts]

def generate():
    obj = (
        cq.Workplane('XZ')
        .rect(10, 10)
        .extrude(10))

    split = (
        cq.Workplane('YZ', obj.val().Center(), obj.val())
        .workplane()
        .split(keepBottom=True)
        .solids('<Y')
        .val())

if __name__ == '__main__':
    main()

Backtrace

This is a (scrubbed) backtrace from my program.

adam-urbanczyk commented 3 years ago

Looking at the backtrace, the crash happens in the mpi4py module. Are you able to debug what is happening there? Is this problem occuring only with MPI (and actually what is the point of using MPI)?

ReubenVandezande commented 2 years ago

I'm having a hard time consistently reproducing this error.

I use MPI since I use this on a remote server with a large number of processors (~20-500 procs depending on use case) and since I also use it with slurm. The output here is while running on the remote server.

adam-urbanczyk commented 2 years ago

We could make this configurable in principle. Is your use case a one-time thing or do you expect that more people are going to use CQ in such a context? Could you disclose some more details on what are you using CQ for?

ReubenVandezande commented 2 years ago

I'm running CQ in parallel with an engineering level CFD code (super fast runnning, ~1 second per run) to optimize an aero-body. I use CQ to determine mass (volume) and centroid as well as to validate against geometric constraints. There are a significant (20+) number of input parameters and output metrics, so the optimizer needs millions of evaluations to come close to convergence. I can't really give any specifics, but hopefully that gives a better idea.

I can definitely see this application of CQ used in the future by me (and possibly others), so a more permanent solution would be beneficial, but with the current workaround I don't see it as a high priority. I'd volunteer the contribution myself, but I'm not familiar with contributing to projects/CQ.

I'll also keep trying to come reproduce the problem, but it's not cooperating right now.

ReubenVandezande commented 2 years ago

Also, using CQ in a shared environment causes it to use ALL processors available, which makes me think that the reason this is so hard for me to consistently reproduce is that it may also be CPU/RAM/architecture dependent.

I think that fact in and of itself should be a red flag. Could we have this as a configurable, ie. _bool_op may use up to X processors?

ReubenVandezande commented 2 years ago

I successfully recreated the issue! I just made a simple box, added a bunch of boolean operations, and ran two simultaneous MPI instances:

I ran this on the same shared-memory machine, same directory, different bash sessions, with SetRunParallel(True):

Terminal 1: mpiexec.hydra -n 10 python force_segfault.py

Terminal 2: mpiexec.hydra -n 10 python force_segfault.py

# force_segfault.py
import cadquery as cq

import faulthandler
faulthandler.enable()

def main():
    while True:
        generateGeometry()

def generateGeometry():
    width = 400
    height = 500
    thickness = 300

    result = cq.Workplane('front').box(width, height, thickness)

    for i in range(20):
        result = (
            result.workplane(centerOption='CenterOfBoundBox')
            .split(keepBottom=True))

if __name__ == '__main__':
    main()
