May, 6-8 2024: Modernization of the power supply
Dear users!
Due to the planned modernization of the power supply in one of the modules
of the computer room, most MICC services will not be available
from 9:00 05/06/2024 to 18:00 05/08/2024.
We apologize for the inconvenience.
Update batch system SLURM (10/11/2023).
Dear CICC users!
from 08.11.23 13:00 to 10.11.23 13:00 please do not start new tasks in SLURM. It is planned to update the batch SLURM system at the CICC farm due to a serious security hole in the current version. So, updating SLURM databases is lengthy and not easy, the process takes a lot of time, tasks in queues or running ones can fail. The actual update will take place on 11/10/23 from 13:00 to 21:00.
Updating EOS (07/07/2022).
Dear EOS Users!
Due to the need to update to the new version of eos5,
all directories in the /eos/… tree will be inaccessible today 07/07/2022
from 17:00 to 19:00.
We apologize for the inconvenience.

Dear users of LIT JINR!
We bring to your attention the following changes to the CICC infrastructure:
From 2021, the dCache storage system, although it remains in the LIT cluster infrastructure, will be available for data storage only in ATLAS and CMS.
An EOS system is provided to store user data.
Instructions for using the EOS system can be found here.
It is planned to switch from the distributed computing management system PBS BATCH TORQUE to SLURM.
Instructions for using the SLURM system can be found here.
A new user interface has been introduced – a gateway for external connections: lxui[01-04].jinr.ru
2019.
Dear Users of CICC!
The CICC has CVMFS and EOS subsystems installed, which will serve as the basis for storage and access with large repositories of programs and large data.
CVMFS service to deploy large software packages of collaborations operating in the WLCG. At present, we already have software versions NICA, BM @ N, MPD (/ cvmfs / nica, / cvmfs / …) and occupy 9.5 GB.
EOS is designed to store and access large amounts of information. Currently our EOS has a capacity of 4PB. It is common to Tier1 and Tier2. Experiments are currently used to store raw data: BM @ n ~ 81TB, MPD ~ 84GB simulation data, ALICE 712TB.
EOS short insruction is here.
At JINR, a single user authentication system, Single Sign-On (SSO), which provides access to pin.jinr.ru, disk.jinr.ru, lxpub {01-05} .jinr.ru, the Document DatabaseJINR, ADB2, SED.
You can get the sso-login-password either after receiving registration at the LIT farm, or from the system administrators of your Laboratory, or at the JINR Network Service (LIT, page 216, tel.6-34-88, noc@jinr.ru)
By changing the password through any of these services, you automatically change access everywhere.
Announcement. March from 20 to 22
From March 20 to 22, the Dzhelepov Laboratory of Nuclear Problems (DLNP) farm has been transferred to the “unscheduled downtime” mode. Therefore, access for some users to the LIT farm whose “home directory” is located on the DLNP AFS server is temporarily unavailable.
2017.
On December 26 and 27 all CICC services will be stopped to replace LAN routers and reorganization power supply systems. Starting new jobs on the batch will be stopped on the 24th of December at 12:00.
