Access Instructions

All public data sets are available on both commodity internet connections and high speed StarLight/Internet2 connections. We recommend using rsync or UDR to download the data.

Downloading with UDR (UDT enabled rsync)

UDR is a wrapper around rsync that enables rsync to use the high performance UDT network protocol, which can greatly improve download speeds, especially over high speed networks. Once installed, the only change is placing the udr command before the same rsync command you typically use to download the data. UDR is open source and under active development, the most recent version is available on github. At the moment, UDR is not enabled on the transfer node. The functionality should return shortly. Use rsync in the meantime.
