[petsc-users] Requesting multi-GPUs

[Manuel Valera]

Hello guys,

I am working in a multi-gpu cluster and i want to request 2 or more GPUs,
how can i do that from PETSc? evidently mpirun -n # is for requesting
processors, but what if i want to use one mpi processor but several GPUs
instead?

Also, i understand the GPU handles the linear system solver, but what about
the data management? can i do DMs for other than the linear solver using
the GPUs
?

Thanks once more,
