BUG: Hashing/caching in parallel #3732

will-saunders-ukaea · 2024-08-13T11:42:20Z

Describe the bug
Running with multiple ranks intermittently causes errors to be thrown like:

Traceback (most recent call last):
  File "/home/js0259/venvs/nesodrake-2024_08_12/src/firedrake/firedrake/interpolation.py", line 837, in _interpolate
    assembled_interpolator = self.frozen_assembled_interpolator
                             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'SameMeshInterpolator' object has no attribute 'frozen_assembled_interpolator'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/js0259/venvs/nesodrake-2024_08_12/src/PyOP2/pyop2/global_kernel.py", line 349, in __call__
    func = self._func_cache[key]
           ~~~~~~~~~~~~~~~~^^^^^
KeyError: 136635048558704

During handling of the above exception, another exception occurred:

I have a Firedrake install from 17/07/2024 which does not exhibit the issue and an install from 12/08/2024 which does.

Steps to Reproduce
Steps to reproduce the behavior:
WIP MFE - As the error is intermittent getting an backtrace to isolate the behaviour to make a MFE around is work in progress.

I have had the most success reproducing the error by:

cleaning the cache.
launch code sequentially (runs)
launch with 2 ranks

Working on MFE.

Expected behaviour
Runs without error.

Error message

See above.

connorjward · 2024-08-13T12:12:29Z

Can you share the differing bits of generated code?

JDBetteridge · 2024-08-13T12:35:09Z

This looks suspiciously similar to a parallel cache coherency issue I ran into recently (noted in these minutes). Are you running your code over multiple communicators, or just COMM_WORLD?

Also it would be good to see the differing code as Connor says: Take a look in /home/js0259/venvs/nesodrake-2024_08_12/.cache/pyop2/mismatching-kernels

will-saunders-ukaea · 2024-08-13T12:52:51Z

On the Firedrake side there is just COMM_WORLD. We have some communicators that we create/destroy in C++, these are never passed to Firedrake,

Miss-matched files are hopefully attached.

At the interpolation call [11] one rank is trying to interpolate a scalar valued function and the other rank a vector valued function. I do have vtu output calls for a vector valued function and a scalar valued function, both the backtraces are on the scalar valued write call.

# One rank:

(Pdb++) p expression
Coefficient(WithGeometry(FunctionSpace(<firedrake.mesh.MeshTopology object at 0x728e9c1041d0>, VectorElement(FiniteElement('Discontinuous Lagrange', triangle, 1, variant='equispaced'), dim=2, variant='equispaced'), name=None), Mesh(VectorElement(FiniteElement('Discontinuous Lagrange', triangle, 1, variant='equispaced'), dim=2, variant='equispaced'), 14)), 53)
(Pdb++)

# The other rank:

(Pdb++) p expression
Coefficient(WithGeometry(FunctionSpace(<firedrake.mesh.MeshTopology object at 0x734d44054410>, FiniteElement('Discontinuous Lagrange', triangle, 1), name=None), Mesh(VectorElement(FiniteElement('Discontinuous Lagrange', triangle, 1, variant='equispaced'), dim=2, variant='equispaced'), 14)), 36)

will-saunders-ukaea · 2024-08-13T13:53:08Z

One rank, the "vector" one, is on line 529 of firedrake/output/vtk_output.py processing the mesh coordinates and the second rank, the "scalar" one, has progressed to line 531 to process the actual function to write.

I haven't seen it fail if I comment out the solve call.

not the issue here but you can use PETSc.Sys.Print to ensure only one print statement in parallel.

Oh nice, thanks.

I had hoped that this FInAT PR and this Firedrake PR would have sorted the issue. Unfortunately not!

It seems that the error is here on line 462.

A finat.finiteelementbase.FiniteElementBase is being used for comparison, but it does not have a stable (or even useful) hash as noted in this comment. I think one solution would be to use a finat.ufl.finiteelementbase.FiniteElementBase subclass here. Maybe someone knows better than me how we fix this!

I think for this case we usually compare UFL elements instead of FInAT ones. We just should be careful because sometimes we don't consider vector-ness when we make the FInAT element.

I think we should probably use the UFL element here and perhaps make eq and/or hash raise an error for FInAT elements to catch any more of these.

* Fixes #3732.

@will-saunders-ukaea can you try connorjward/fix-3732 (#3807) and see if that resolves things for you? It did for me.

Then just need to ensure that the remaining tests pass.

JDBetteridge · 2024-10-24T10:52:30Z

Seems to be fixed, closing
