Yeah use the hostnames which slurm knows and it will work perfectly. You might also want to increase the max switch wait parameter in slurm which offhand I cannot remember how to do but I do remember that the default maximum is about 10 minutes which I consider to be a bit on the short side if you have a nontrivial blocking factor and a long interconnect bound application. It is documened however.
