ccpp-physics release in support of ufs-v1.0.0 and gmtb-scm v4.0.0

CCPP-SCM Version 3.0

The v3.0 release code may be obtained from this GitHub Repository. It is part of the bundled CCPP+SCM release, which can be obtained from:

git clone --recursive -b v3.0 https://github.com/NCAR/gmtb-scm
cd gmtb-scm

In order to run the IPD-only version of gmtb-fv3 with ccpp-physics, the full set of physics, CCPP-compliant and non-CCPP-compliant, are required (unless the driver code is changed). This tag is a snapshot before removing the non-CCPP-compliant physics from the master branch starting 05/14/2018.

Ongoing development work lead to differences in the results that break bit-for-bit tests with the IPD-build of FV3v0+CCPP, even though the CCPP-build is still correct. This is presumably caused by different compiler optimizations taken once the non-CCPP-compliant physics were removed, because none of the code changes would affect the IPD-build only. This tag saves the last bit-for-bit identical version of the IPD build for future reference.

This release is pushed to a public release repository, 4/8/2018

This tag holds the split/separated GFS physics at a point where the entire physics are still run through IPD and the GFS {physics,radiation} driver. It also performs the IPD_setup_step at the beginning of every time step in one step over all blocks. It seems beneficial to keep this version in case the changes to run IPD_setup_step per block turn out to have an adverse effect on the runtime performance.
