The current status of the LIT Cluster:
User authorization through a new base Kerberos5 has some special
- Batch tasks are working and AFS is also accessible for those tasks. It is
necessary to be registeres in the base Kerberos 5 (see item 1). if the
password was chenged by kpasswd command, run 'pbspwstore' command - to store
the new password in Batch.
Commands ssh/scp also work in Batch, but on ssh 1 protocol, for example
ssh -1x lxpub01.jinr.ru
scp -1Bqp lxpub01.jinr.ru:<file> <dir>
- Program packages CERNLIB and ROOT have been installed on interactive
machines with OS SL4 lxpub01-lxpub03.
Variables of environment CERN-ROOT, ROOTSYS are installed automatically when
entering the system.
The compilers and utilities Intel and paralleling system MPI will be

The current status of the LIT Cluster is as foolows:
In cooperation with the JINR NEtwork Service, transfer of the users'
database and their passwords from Kerberos 4 to Kerberos 5 has been done.
Now you can change a password with "kpasswd" command.
Tasks in Batch work, and AGS is accessible for those tasks too. At
present commands ssh/scp do not work from batch. We expect to resolve this
problem soon. System MPI has not been installed on computing batch nodes.
The following program packages haven't been installed on interactive
machines with OS SL4 lxpub01-lxpub03:
- compilers and utilities Intel;
- MPI system for paralleling.
The packages will be installed in the nearest future.
Some problems can arise with FTP access to Web pages on machine

Dear users of LIT cluster,
Machines lxpub01-lxpub03 were renamed into lxpub05-lxpub07.
The current problem is to enter the machines lxpub01-lxpub03. This problem
is expected to be solved within 1-2 days.

Dear users of LIT cluster,
The LIT cluster machines have developed a fault at present:
- In the days ahead, the batch processing system will not run users'
tasks from AFS directories (HOME).
The problem is supposed to be solved till
14 May, 2007.
- The data storage system dCache does not operate. Its complete
start-up will take several weeks. Access to directories in dCache
/pnfs/jinr.ru/user is expected to be restored by 14 May.
- All accounting nodes of the batch system have been installed from
OS SL44 (Scientific Linux) in variant x86_64 (CPU architecture). However,
there are libraries of compatibility with architecture CPU i386 and OS SL3.
We strongly recommend you to re-arrange the programs for x86_64
Since 11 May, 2007 the following interactive machines will be accessible for
lxpub01, OC SL44 x86_64
lxpub02, OC SL44 x86_64
lxpub03, OC SL44 i386
lxpub04, OC SL308 i386
- Till 14 May 2007 packages ROOT and CERNLIB will not be accessible
on lxpub01-03 machines.
- Local scratch areas are accessible for users (/scr/u) on the
interactive machines since 14 May:
lxpub01, lxpub02 - 200GB
lxpub03 - 50GB
lxpub004 - 15GB
It is planned to increase scratch on lxpub03, lxpub04 up to 100GB by late

Attention to Users of LIT Cluster!
From 30 April to 9 May, 2007, a new equipment is expected to be installed at
the JINR Central Information Computing Complex.
This will demand a
considerable re-configuration of the infrastructure. Thus, all the computing
farms and most disc servers will be put out of operation.
Access will be provided to:
- interactive machines lxpub01 - lxpub03;
- server of scratch directories on the interactive machines /scrc;
- WWW, FTP, MAIL servers;
- AFS servers of home directories support.
Warning! The mentioned machines may be turned off (during not longer
than 4 hours though).
We make our apologies for possible inconveniences.
