From 05cd9b97b25eb80dc9fb913dbe889be330b6b708 Mon Sep 17 00:00:00 2001 From: Marshall Ward Date: Fri, 15 Dec 2023 15:23:11 -0500 Subject: [PATCH] Disable FPEs in MacOS testing Due to poor handling of floating point in HDF5 1.14.3, it is currently not possible to use floating point exceptions (FPEs) whenever this version is present. The GitHub Actions CI nodes would randomly select either 1.14.2 or 1.14.3, and would raise an FPE error if 1.14.3 was selected. Additionally, the homebrew installation does not provide a clean method for selecting a different version of HDF5. Thus, for now we disable FPEs in the MacOS testing, and hope to catch any legitimate FP errors in the Ubuntu version. We will restore these tests as soon as this has been fixed in an easily-accessible version of HDF5. As part of this PR, I have also moved the FCFLAGS configuration to the platform specific Actions files, allowing for independent compiler configuration for each platform. --- .github/actions/macos-setup/action.yml | 15 +++++++++++++++ .github/actions/testing-setup/action.yml | 11 ----------- .github/actions/ubuntu-setup/action.yml | 12 ++++++++++++ 3 files changed, 27 insertions(+), 11 deletions(-) diff --git a/.github/actions/macos-setup/action.yml b/.github/actions/macos-setup/action.yml index fecbe787b5..4c248abd11 100644 --- a/.github/actions/macos-setup/action.yml +++ b/.github/actions/macos-setup/action.yml @@ -16,3 +16,18 @@ runs: brew install netcdf-fortran brew install mpich echo "::endgroup::" + + # NOTE: Floating point exceptions are currently disabled due to an error in + # HDF5 1.4.3.
