+### The Merlin7 'interactive' partition
+
+On `merlin7`, is recommended to always run interactive jobs on the `interactive` partition. This partition oversubscribe
+CPUs (up to 4 users can use the same CPU), and has the highest priority. In general, access to this
+partition should be quick, and can be used as an extension of the login nodes.
+
+Other interactive partitions are available on the `gmerlin7` cluster, however, the main user is for CPU access only.
+Since the GPU resources are very expensive and we don't have many, please do not submit interactive allocations on GPU 
+nodes using GPUs unless strongly justified.
