PGI 16.05, CCE 8.5.1 and CrayPat 6.4.1 are installed on Hexagon as non default versions.

As the newer CCE and CrayPat installations are rather experimental, to access version 8.5.1 of the Cray compiler and 6.4.1 version of the CrayPat one needs to run:

module use /opt/cray/pe/modulefiles

NB. No extra steps are required to access PGI 16.05

We have upgraded the SSH server on hexagon to address some security issues.

If you can not log in anymore using your SSH key, but only password, please check the content of ~/.ssh/authorized_keys file for entries like from="" and change the hostname to IP address. Starting with this version only IP addresses and not host names may be used in the authorized_keys file.
Edit: authorized_keys file provides fine tuning for client access. If you would like to find out more about it, you may read sshd(8) man pages.

DSA key types are not considered safe anymore and we will phase them out soon. A new syslog entry will be added in the following days with more information about it.
