@pyhalov my machine does not have AVX

[pyhalov]

How can we make tests reproducible? Remove architecture-dependent results? Avoid shipping results relying on tests just pass?

[alarcher]

@pyhalov Do we talk about valgrind here or openexr? It seems you posted on the wrong PR. If it is openexr, I'll look at disabling AVX.

[pyhalov]

Yes, wrong PR

[alarcher]

@pyhalov Do you need something more on this PR?
