That is superlu_dist and hypre.<br>
<br>
Yes, but both backends are rather primitive and will be a little struggle to use.<br>
<br>
For superlu_dist you need to get the branch barry/fix-superlu_dist-py-for-gpus and rebase it against master<br>
<br>
I only recommend trying them if you are adventuresome. Note that PETSc's GAMG can also utilize the GPU.<br>
