My scp file transfer crashes with time limit. What can I do?

File transfer with scp (ssh secure copy) may consume significant amounts of CPU time due to the inherent data encryption/decryption. In order to allow for the transfer of big files to and from JUROPA/HPC-FF the CPU time limit has been specifically increased on the GPFS nodes.

CPU limits
Login nodes1800 sec
GPFS nodes21600 sec

For this reason, it is strongly recommended to use the GPFS nodes for file transfer instead of the Login nodes.
