[petsc-users] Hypre runtime switch CPU/GPU

[Milan Pelletier]

Dear PETSc users,

Is there a way to switch a runtime setting for PETSc+Hypre to run on CPU, even when it has been compiled to allow for GPU support?
I looks like setting the matrix and vector types to respectively "seqaij" and "seq" results in GPU computation when Hypre is used as a preconditioner. I thought GPU would be used only when mat_type is set to "hypre", following the examples provided with the last release.

Thanks for the help,
Best regards,

Milan
