Is that the container you are referring to?

Because in that case, it quite clearly says "SingleNode" in the version
label.
At any rate, for a cluster it is generally better to build the Charm++
library (which NAMD uses to achieve multi-node parallelism) to be better
integrated with the cluster's software configuration.
Multi-node, however, will also require the older, hybrid CPU-GPU scheme and
does not support the pure-GPU scheme of 3.0. With the latter you are
limited to running one replica over one node at most, and perhaps do
replica-based methods across multiple nodes (all is explained in the NAMD
3.0 alpha webpage).
