Add cuda-related variants for Albany and Trilinos #31

Closed mcarlson801 closed 1 month ago

mcarlson801 commented 3 months ago

This PR adds variants to albany and trilinos-for-albany spack recipes to support CUDA builds.

A few notes about the included variants: 1) DFad Sacado types do not work on GPU so I've added an SLFad variant to Albany as an alternative that will work for all GPU cases. 2) CUDA Unified Virtual Memory (UVM) is off by default but can be enabled by adding +uvm 3) Same for Tpetra's GPU_AWARE_MPI (add +aware to enable) 4) Added +zen3 and +ampere80 architecture flags for Perlmutter-GPU

@xylar I think these are all the changes we need for a GPU build. Is there anything else we need to do before it can be merged?
