Error while running with SEMFEM preconditioner

[nandu90]

I am getting the following error while running with SEMFEM preconditioner, using v23.0.0 (4f87e0e)

ERROR: Recompile with HYPRE GPU support!

This is on the nek5k machine, NVIDIA-A100. The code runs fine with the default (semg) pre-conditioner on GPUs

Seems like I am missing something during compilation. Any ideas?

Thanks!

You want to compile with -DENABLE_AMGX=ON or -DENABLE_HYPRE_GPU=ON. On systems with NVIDIA GPUs I would recommend to use AMGX at least for now.

Thanks @stgeke

I tried with either of the options on Polaris. Get the following error:

On nek5k the code quits without throwing a helpful message.
