If you would like to transfer data from your own system to our cluster, you have to use either the scp or the sftp protocol. Although data transfers are possible to or from any dialog system, we recommend that you use one of the systems, dedicated to the purpose of file transfers: copy, copy18-1 or copy18-2.

A single copy stream will probably achieve no more than about 80 MB/s. To get higher transfer rates you have to start several copy processes in parallel.

Linux Clients

You may simply use the scp or the sftp commands to copy files from a Linux station to our cluster.
