LAMMPS-23Jun2022-foss-2022a-kokkos : kokkos_arch variable not detected

[theGitpster45]

Greetings, For a few weeks I tried to deal with a bug that keeps me from successfully installing LAMMPS in my cluster. It always return the following error:

WARNING: kokkos_arch not set. Trying to auto-detect CPU arch. (...) Couldn't determine CPU architecture, you need to set 'kokkos_arch' manually. (took 17 secs)

I tried to apply the following workarounds, but none worked:

• Copy the original easyconfig for LAMMPS-23Jun2022-foss-2022a-kokkos and set either the configopts or buildopts options. These are the values I tried:

  • "-DKokkos_ARCH=HSW"
  • "-Dkokkos_arch=HSW"
  • "-DKOKKOS_ARCH=HSW"
  • "-DKokkos_ARCH_HSW=ON"
  • "-Dkokkos_arch_HSW=ON"
  • "-DKOKKOS_ARCH_HSW=ON"
• run the eb command with the --try-amend option (--try-amend=configopts="-DKokkos_ARCH=HSW"

It's not a Lammps option, it's an option for the easyconfig recipe. For what you want, this should work --try-amend=kokkos_arch=HSW

It worked as you said ! Many thanks @ocaisa :smiley: !!
