About LCRC Jazz Accounts
All computing carried out on Jazz is associated with a Jazz "account".
This account is used to log onto the cluster and run jobs on the
compute nodes. If someone has a Jazz account, then they have a login
name that is recorded in the Jazz user database.
This web page describes accounts in detail, including policies,
concepts and so on. There are several other useful web pages related
Who Can Get an Account
Any ANL employee can get an account on Jazz simply by registering for
their account on the Jazz web pages. An ANL employee in this context
means "anyone with an ANL ID number", which includes students, guest
appointments, and retired ANL personnel. (Checks to confirm the
authenticity of the registration will be carried out.)
Anyone non-ANL employee wishing to have an account on Jazz must fill
out a Jazz account request form, and as part of that, must indicate an
ANL employee who will "sponsor" or vouch for their account.
Each such sponsor will be asked annually to confirm that the accounts
that they have sponsored should continue to be kept active on Jazz.
Someone with an active account can login to the Jazz front ends nodes,
accessible as jazz.lcrc.anl.gov. That account will
have some home directory space, can transfer files to and from that
space via the login nodes, and can carry out development activities
such as editing, compiling, and so on.
However, in order to do more than interact with just the Jazz
front-end nodes, an account must also be associated with an active
project that has a positive allocation of time on the system.
Detailed information about projects, including policies, concepts,
background, etc. may be found on the Projects page.
All holders of Jazz accounts must abide by all appropriate LCRC and
ANL computing usage policies. These are described at the time of the
account request and include requirements such as using a sufficiently
strong password, appropriate use of the system, and so on. Any user
not following these requirements will have their account disabled.
Furthermore, Jazz is intended to be used as a computing resource for the
Laboratory, not as a general-purpose login/email/file-server system for
Laboratory employees. If someone is using the system extensively but not
carrying out any computational activities, their account may be disabled.
An account can be in any one of several states:
Last Updated: 5/19/2003
- Pending: A pending account is one that has been requested
but has not yet been created.
- Active: An active account is one that can be used to
interact with the jazz front end systems. This is the normal state
for jazz accounts that are being used.
- Disabled: A disabled account still exists on the system,
meaning that the account is in the database and the user's files exist
on disk, but that cannot be used to interact with the jazz front end
systems. An account might be disabled due to misuse of the account,
security concerns, or because the account is no longer being used.
- Expired: An expired account is one that has at some point
in the past existed on the system and is thus in the records and
backups, but that no longer has access to the systems or files on
disk. For most practial purposes, an expired account no longer
