+# ============
+# -N =                 nodes
+# -n =                 tasks (MPI ranks, usually = G)
+# -G =                 GPUs (full Perlmutter node, 4)
+# -c =                 CPU per task (128 total threads on CPU, 32 per GPU)
+#
+# --ntasks-per-node=   number of tasks (MPI ranks) per node (full node, 4)
+# --gpus-per-task=     number of GPUs per task (MPI rank) (full node, 4)
+# --gpus-per-node=     number of GPUs per node (full node, 4)
+#
+# --gpu-bind=single:1  sets only one GPU to be visible to each MPI rank
+#                         (quiets AMReX init warnings)
+#
+# Recommend using --ntasks-per-node=4, --gpus-per-task=1 and --gpu-bind=single:1,
+# as they are fixed values and allow for easy scaling with less adjustments.
