Add support for TACC Vista machine (gg and gh partitions). Adding vista-gh and vista-gg machine configs for testing on the vista machine at TACC. vista-gh are grace-hopper nodes (1 grace CPU, 1 nvidia hopper GPU). vista-gg are grace-grace nodes (2 grace CPU's) Primary purpose is to save the machine configs for future testing when/if needed. Only minor testing was done, including ne30 eamxx/eam cases. The change in cime_config/machines/cmake_macros/gnugpu.cmake mimics change in cime_config/machines/cmake_macros/gnu.cmake for different CPU archs. Testing with nvidia also revealed an improvement in components/cmake/build_model.cmake They have gcc v15 installed and I made one minor fix here to share/timing/private.h to allow building. There are also some minor changes in ekat/cime (already in PR's) required for the testing I did. [bfb]

There was a problem hiding this comment.
This wound up breaking the build on GCE. Claude has a fix but it will need to be tested on other machines.
