Hello.
I've been building different versions of VASP for years, but 2 things I've never done was build with GPU support (I tried once, but not sure if I ever got it working right) or a build using Spack.
I've searched the forum but haven't found a comprehensive set of instructions for building VASP using Spack with GPU support enabled. I never built anything with Spack before, so you can say I'm jumping into the pool with both feet, and the pool is on fire.
So please pardon my ignorance here, but if someone has already gone through the pain, I would love it if you could share some steps with me, especially if there are traps inside the changes to makefile.include to make sure the GPU actually does get used. In other forum posts I saw some information regarding some defines that should be set in makefile.include.
Thank you!
