Login to GSI

A number of central interactive Linux computers can be used to login using SSH (read SshUsage for more details). If you use lx-pool.gsi.de or one of the other pools listed below for login, it will direct you to a pool of machines and distribute users homogeneously among them (load-balancing).

Purpose

Users can access their home-directories on all interactive machines, as well as central FileSystems like /d/ (data storage) or /s/ (global scratch space). Dedicated pools of interactive machines allow external access for all users from outside the GSI network. Machine pools providing only internal login feature access to the HPC computing clusters (BatchFarm) and the Lustre file-systems Hera and Nyx.
