This is an old revision of the document!
From the Blue Sky Studios donations of hardware we have created a high performance compute cluster. Named sharptail. A sharptail saltmarsh sparrow is a secretive and solitary bird, seldomly seen most often only heard by its splendid song, which inhabits a very narrow coastal habitat stretching from Maine to Florida.
Because of limitations in the hardware, cluster sharptail can only be reached by first establishing an SSH session with petaltail or swallowtail, and then an SSH session to sharptail. So the cluster sits entirely behind those login nodes.
