    Dear Users of CICC!

    After the required changes of OS of the batch access in view of fransferring the computing machines (Worker Nide - WN) to OS Scientific Linux SL release 5.3 and MIT Kerberos 5, it is necessary to correct the task start scripts of users. This should be done only in case when the file remote copying instruction - "scp" - is used. One should correct this instruction so that it uses a protocol SSH version 2, not version 1, how it was earlier.
    Thus, if the script contains call "scp",
    scp -p1 ... ,
    you should change it for scp-p2 ...

    Dear Users of CICC!

    New photogallery is opened.

    Dear Users of CICC!

    Addition to the news N1 of 18.09.2009.

    In order to speed-up the changeover to OS SL53, a new interactive machine will be installed which works under OS SL53 with 64-bit architecture. The interactive machines lxpub01 -:- lxpub03 will operate under OS SL48 during 1-2 months approximately.

  • 18 September 2009

    Dear Users of CICC!

    1. We are going to upgrade CCIC' batch farm and interactive machine to the OS Scientific Linux SL release 5.3 (SL53). Due to this upgrade, all batch resources will be unavailable from 25 September till 1 October.
      Our apologies for the late announcement of this urgent action.

    2. There is a problem in one of AFS servers ownered by Laboratory of High Energies (not in LIT). Due to this problem some users lost HOME directories. We are going to create temporary and empty HOMEs for such users on LIT' own AFS servers at 31.08.09 and done that for the users registered at LIT farm.

    Dear Users of CICC!

    A presentation of two important infrastructure projects - a new computer communication link "Dubna - Moscow" and a Grid-segment of JINR - took place in frames of the 31-st Session of the Programme Advisory Committee for Particle Physics that was held at the Joint Institute for Nuclear Research.
    For more details please see the weekly "Dubna" of 19 June, 2009, No. 25 and the weekly "Vstrecha" of 18 June, 2009, No.25.

    Dear Users of CICC!

    New Recommendations: "Systems of computer algebra on the lxpubXX farm"

  • 26 May 2009

    Dear Users of CICC!

    In view of the new equipment has been entered at the JINR CICC the hardware configuration is changed.

  • 15 May 2009

    Dear Users of CICC!

    1. At the JINR CICC new computing resources have been put into operation:
      - 40 machines Supermicro Twin
            8-kernel Intel Xeon E5420 2.50GHz
            16 GB RAM
            250GB SATA-II HDD;
          - 10 machines in the structure of Supermicro Superblade
            8-kernel Intel Xeon E5410 2.33GHz
            16 GB RAM
            2 x 150GB SATA-II HDD
            Infiniband network adapter.
    2. In view of the reorganization of the power supply system in the CICC hall, sometimes there are power supply failures and part of the computing resources is turned off.

    3. Due to changing the scheme of the network connections in CICC and replacements of the network equipment and the cable system, the network sometimes works unstably.

    4. Adjustments of the system of batch operation have been changed at the CICC computing farm:

      - Maximal astronomical time of computation is limited by101 hours;

      - Maximal CPU time for a single-processor problem is limited by 100 hours;

      - Maximal CPU time for a multiprocessing problem (MPI) are limited by 8x100= 800 hrs.

    5. Adjustment of the system of batch operation is not complete yet and will vary during the nearest weeks.

    6. The completion of all the work on putting new technical equipment at the JINR CICC and the termination of adjustments of all hard- software complex is planned by the end of May.

    Dear Users of CICC!

    Due to upgrade of JINR border gateway (cisco router) and LIT LAN maintenance we expect a few network interrupts for about 30-40 minutes each at 2009-03-12 from 14:00 till 18:00.
    Sorry for any inconveniences.

  • 18 February 2009

    Dear Users of CICC!

    A Web-monitor has been started-up at the JINR computing farm where one will be able to get acquainted with operation of the computing cluster as well as with information on user's tasks.

  • 9 February 2009

    Dear Users of CICC!

    12 February from 15:00 up to 23:00 some instability of the cluster expected due to replacing of main router. We ask you do not submit long jobs to the cluster at this time. Sorry for any inconveniences.

  • 22 January 2009

    Dear Users!

    Our WN resources on the farm will be lowered from 560 to 240 CPUs till the next monday - 26.01.2009 due to moving shelfs in the computing hall.
