My current research project relates to implicit time integration schemes for discontinuous Galerkin methods. Therefore, we need to solve a linear system at every time step. If we consider a nonlinear system then we need to linearize and assemble the Jacobian matrix. My current task is to assemble the Jacobian matrix on a GPU. To ease the development process then I request interactive sessions on the cluster. Here is what the command I use to request the interactive sessions:

srun -N 1 --partition=gpu-partition --time=2:00:00 --pty bash -i

I request one node (which has two GPUs) and for 2 hour chunks. This gives plenty of time to test the code. The partition will have to change depending on the cluster you are working on.
