Issue installing TChem through master_bld.sh

[borjapedro]

Hi all,

so, first of all, I am completely new to TChem, and I am trying to use it in our CFD solver for reaction rates computation in a CPU/GPU environment.

However, I followed the instructions, and when executing the master_bld.sh script to download all dependencies, I get following error in the Tines compilation:

I checked the current version of Kokkos, and indeed the requested "impl/Kokkos_ViewMapping.hpp" does no longer exist.

How can I get TChem running with the script? Or is the script deprecated?

Thank you in advance and regards,

Borja

Hi @borjapedro

The main branch of TChem is not working with the current version of Kokkos. Please use Kokkos version 3.7.0.

Do you mind sharing more information about your project? You can email me directly at odiazib@sandia.gov.

A followup question: Since TChem seems to only be working with an older version of Kokkos, is this tchem version compatible with newer AMD GPUs? Is there any work going on regarding compatibility with newer releases of Kokkos?

I have seen there is already a version of Tines working with Kokkos 4.2, which already provides support for the newest of AMD APUs (mi300).
