Issue or question about MOOSE

I have successfully installed MOOSE once before through CONDA, I want to install MOOSE with HIP support now, I have installed petsc with HIP support now. But don't know how to make MOOSE use this petsc directly. At the same time, the petsc I installed is less STRUMPACK than the petsc MOOSE downloaded by default. I wonder how this will affect my subsequent work? Or is the STRUMPACK a must for MOOSE?

Hello

strumpack is not necessary for MOOSE
You can specify the PETSC_DIR then follow instructions for HPC installs of moose starting at libmesh

I think this problem is because only one library is 64-bit compiled and the other library is 32-bit compiled. How can I modify configure_libmesh.sh to solve this problem

Hello

You can use --help on this script or on the configure script in libmesh to find the options to pass to change this

@ljeft there appears to be a fundamental problem with the libMesh configure step; it appears to be a bug, not something you're doing wrong. The PETSc configure indicates that it's using 64 bit indices. However, when you pass --with-dof-id-bytes=8 to libMesh, configure is failing when it shouldn't be. That's why @roystgnr is asking:

Could you let me know what you get from grep PETSC_USE /opt/petsc/include/petscconf.h? Unless you don't see anything, in which case I'd be curious about find /opt/petsc -name petscconf.h

I am now trying to continue my work with a lower version of petsc, can you tell me the best version of petsc to choose?

The most tested version is 3.20.3
