Introduction
This user's guide for the CMS supercomputer is intended to provide the minimum amount of information needed by a new user of this system. As such, it assumes that the user is familiar with basic notions on scientific computing, in particular the basic commands of the Unix operating system, and also with basic techniques for the execution of applications in a supercomputer.
The information in this guide includes basic technical documentation about the CMS supercomputer, the software environment, and also on available applications.
Please read it carefully and if any doubt arises don't hesitate to contact our support mail (see below in Getting help).
Connecting to CMS
Once you have a username and its associated password you can get into Altamira system, connecting to one of the the 2 login nodes at altamira1.ifca.es in the case of the first login or altamira2.ifca.es for the second one (see Login node to know more information about the login nodes). The password provided is temporal, you must change this initial password after connecting to IPA. Also use a strong password (do not use a word or phrase from a dictionary and do not use a word that can be obviously tied to your person).
You must use Secure Shell (ssh) tools to login into or transfer file into Altamira. We do not accept incoming connections from protocols as telnet, ftp, rlogin, rcp, or rsh commands. The connection to Altamira must be done in the following way:
$ ssh username@altamiraX.ifca.es (where X is 1 or 2)
Once you are logged into Altamira you cannot make outgoing connections for security reasons (contact us in an exceptional case).
If you cannot get access to the system after following this procedure you can contact us, (see Getting Help to know how to contact with us).
