Archer2

Archer2 is the UK supercomputer, we mainly use it for running CESM2 simulations.

To use it, you need to setup an ARCHER2 account and then connect using ssh.

Resources

  • The Archer2 documentation is good in general.
  • SAFE: Used to manage account and monitor usage.

Getting started

To use Archer2, one needs to obtain a SAFE account, followed by an ARCHER2 login account.

Login Tip

After the first login, to make it easier, I have config file on my local machine at /Users/user/.ssh/config with the following (the same file can have multiple hosts for different supercomputers): 

Host archer2
HostName login.archer2.ac.uk
User jamd
IdentityFile ~/.ssh/id_rsa_archer

This means I can just type ssh archer2 to login directly.

File Transfer

I find it easiest to transfer files with globus. Archer2 gives good instructions on how to do this.
