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,
