From cc97f248ab466eac0174369553080ce700c96ac5 Mon Sep 17 00:00:00 2001 From: ChrisRackauckas-Claude Date: Mon, 9 Feb 2026 16:48:26 -0500 Subject: [PATCH 1/2] Limit downstream tests to ubuntu-only NeuralPDE.jl downstream tests fail on Windows (IOError: kill permission denied in test worker management) and macOS (test timeouts on Fokker-Planck and 2D Wave Equation after 3600s). These are NeuralPDE.jl infrastructure issues, not QuasiMonteCarlo.jl bugs. All downstream tests pass on Ubuntu. OS-specific compatibility is already covered by the Tests workflow which runs on all 3 OS. Also removes hardcoded arch: x64 which causes warnings on Apple Silicon runners.

With n=16, the variance test (rtol=0.5) occasionally fails when sampled points cluster near the center (observed on macOS aarch64). Increasing n to 64 provides much more robust statistical convergence.
