Czars roles and responsibilities

Some users have the privilege to manage the computing resources allocated to their laboratory or their group, to give a new password to a user or to request new resources. These users are called czars in the CC-IN2P3 jargon. There are different types of czars whose roles apply to a laboratory and/or to a group:

  • request czar: he is responsible for the resources requests (CPU/GPU, storage) for his group.
  • account czar: he is responsible for the validation of request for accounts made for a laboratory or, in some case authorized by IN2P3, for non-CNRS collaborators of experiments.
  • password czar: he is responsible of the AFS passwords. He can reset it when a user has forgotten it. Usually a account czar is also password czar but this is not a rule.
  • storage czar: he is responsible of the storage spaces allocated to the group (THRONG, SPS, HPSS, iRODS)
  • computing czar (batch): he is responsible for the management of priorities within his group on the computing platform.

To have a group czars listed, you may use the command lines below from an interactive server (the -p option without any arguments will give the storage czars list):

% laboinfo -l <labo code> -p <typeDeczar={batch,password,requete}>
% laboinfo -g <group name> -p <typeDeczar={batch,password,requete}>

where “requete” stands for “request”.

Request czar

The request czar makes the annual resource request for his group. This request is made in collaboration with the Support team of CC-IN2P3 in order to be as precise as possible in terms of computing and storage needs. The Support team enters this request, which is then arbitrated by the CC-IN2P3 management.

Account Czar

Creation of new accounts

The account czar is the person who has been chosen by his laboratory leader to validate request for new account and laboratory change of a user. This czar does not have the necessary permissions to add a user to a group.

The form to request a new account is available at this address. The account request must be printed and signed by:

  • the laboratory leader;
  • the requesting user;
  • the account czar.

The czar must then send the scan of the signed document as an attached file on the ticket to the user support.

For any operation on your account <username> please refer to the result of the command below:

% laboinfo -u <username> -p compte

For international collaborations, one of the account czar major roles is to request new accounts for people working in foreign laboratories, or non-CNRS staff.


Avoid manual overloading of the form, which prevents automatic processing. In case of delay, error, or explanatory comment, communicate through the ticket.

Do not accept logins such as abbreviation, nickname, fun, initials: they will be rejected, without second choice request.

Group change

You can also contact your account czar when you want to switch group or add a group to your account. You must send an e-mail to your account czar with a copy to the computing czar of the new group. Your account czar will ask for your this modification via a ticket.

Laboratory change

You must fill the same form for account request when you change lab. There is a check-box to indicate that it is for a change of laboratory and not for a new account. The account czar of your new laboratory will sign the request to validate the change.

Intermediate support

Within the laboratories, the account czar is sometimes called “lab czar”. Very often, this czar has a role of intermediate support and trainer for new CC-IN2P3 users working in the same laboratory:

  • manage account opening requests;
  • manage group change requests;
  • train new users;
  • perform user or group registration requests in HPSS.

This czar should regularly check the accounts of his/her laboratory or group and report the accounts to be deactivated. The recommended command to get information about the users of a laboratory or group is:

% laboinfo -h

To find accounts inactive for more than 2 years (the -v option provides e-mail addresses):

% laboinfo -l <lab code> -b 2 -v
% laboinfo -g <group name> -b 2 -v
% laboinfo -l zz -g <group name> -b 2 -v  (for non-CNRS collaborator to a group)

Password czar

The password czar has the privilege to change the password for a user belonging to the same laboratory. In order to identify your password administrators, use the following command from the interactive servers:

% laboinfo -l <lab code> -p password
% laboinfo -g <group name> -p password

These users may reset a password with the following command:

% setkpasswd username

Storage czar

PBS ACL management

The storage czar is responsible for the management of the group disk space and its ACLs. Further details related to this topic can be found on the ACL management paragraph.

To know your storage czar name:

% laboinfo -g <group name> -p

THRONG space management

The THRONG space is not managed by any czar but by users. However your storage czar should be able to give you good advice for an efficient use of your that space.

SPS space management

The SPS is used to store large amount of data temporarily. This space is managed like the Unix directories /tmp or /scratch. When no more space is available, users are invited to clean up. The storage czar is responsible for this area and is entitled to manage quotas. He may give you advice on how to move and delete you data located in this area.

Computing czar

The computing czar requests permission to provide users with access to the restricted queues. This request must be sent to the user support. The computing czar can also contact the Support team to boost a user’s production.
