Arpan, Nice to meet you. -log_view in a petsc option, so I think you can add it to your fvSolution_petsc_pKok_Uof at location like mat_type mpiaijkokkos; vec_type kokkos; log_view; --Junchao Zhang On Fri, Jun 14, 2024 at 2: 44 PM Sircar, Arpan

I tried adding -log_view to my OpenFOAM command since that is what I am running the entire package through. However, it does not recognize that as a valid option. I am not sure where to put that tag in this setup.</div>

We have been working with OpenFOAM (an open-source CFD software) which can transfer its matrices to PETSc to use its linear solvers. This has been tested and is working well on OCLF's Frontier machine. Next we are trying to use the Kokkos backend to run it
on Frontier GPUs. While the OpenFOAM+PETSc+Kokkos environment built correctly on Frontier using the modules sourced (attached file<span> </span><i>bash_petsc4foam_gpu</i>) and configuring PETSc correctly (attached file<span> </span><i>config_gpu</i>), the
GPU solve seems to take more time than the CPU solve.</div>
