If you need to transfer a large amount of data from your local platform to your /project folder at CSCS or viceversa, you have an alternative that might run faster then sftp or scp. The program mpscp can send data-stripes in multiple non-encrypted TCP-streams and enable greater transfer rates. To start the data transfer on /project use the following command:
$ mpscp -m /apps/ela/mpscp/bin/mpscp -a -w 1 yourfile user@ela.cscs.ch:/project/yourgroup
The flag -w controls the number of TCP-streams used in parallel: in the example above only 1 stream is used, but you can increase it of course; you can also transfer directories recursively with the flag -r. Please be aware that you will need to install the mpscp software on your local machine, if it is not yet available.For further information and for downloading the source, please have a look here.
