Computer Services Cell - Computer Facilities

Computer Services Cell (CSC) serves the computational needs of the S. N. Bose National Centre for Basic Sciences. The primary responsibilities of the CSC is to facilitate the centre with an uninterrupted computational services and is officially responsible for the provision of central computing facilities and technical services to support the following aspects of computer and network within the centre.

Overview of CSC responsibilities

  • Day to day Maintenance of centre's computational and networking equipments and planning for better service.
  • Maintenance of centre's Computer Hardware, Operating System and Softwares.
  • Maintenance of center's Network.
  • Maintenance of Computing Clusters.
  • Maintenance of centre's Servers (DNS & DHCP, Web, Email, Intranet, NFS, Antivirus, VPN).
  • Maintenance of Website and other online services.
  • Facilitated with individual email account.


1. CSC Organization Structure

As a concern to the better services, the CSC is formed by two committees -

1.1 Computer Services Cell Advisory Committee (CSC-AC)

CSC-AC is formed by 10 members and chaired by Prof. Tanusri Saha Dasgupta. CSC-AC provides general planning of the growth of computational facilities and makes broad policies as are needed for efficient running of those facilities included policy of allotment of slots to users.

1.2 Computer Services Cell Working Group (CSC-WG)

CSC-WG is formed by 11 members and chaired by Prof. Tanusri Saha Dasgupta. CSC-WG provides day-to-day operational activities along with time-to-time measures of facilities for the very high utilization rate of computational equipments and uninterrupted services.

2. Equipments under CSC

Currently CSC provides services to approximately 500 users including faculties, staff members, and students, and handles more than 400 workstations; 20 black & white and 10 color local and network printers; 5 Scanners; 10 servers; 5 computational clusters. CSC also looking after 2 leased line networks of 1.0 Gbps and 15 Mbps speed for the internet and intranet access. The cell manages 1 router; 3 layer-3 and 16 layer-2 switches; 17 wifi access points, 1 WLC. The internal backbone of SNBOSE network is designed with fiber optic channels for the high speed communication. CSC also provides Virtual Private Network (VPN) access to the restricted users to facilitate local network access from outside internal network.

3. Facilities provided by CSC

3.1. Workstations

CSC provides more than 400 dedicated workstations (HP, Dell PCs) to all faculty, students and staff members to meet individual personal requirement and freedom of work. Fedora, Ubuntu is installed in most of the workstations. Scientific tools are installed as required.

Every workstations along with all other equipments used by CSC are connected with dedicated or centralized power backup (UPS) for the uninterrupted operations.

3.2. Network

CSC is dedicated to facilitate SNBNCBS users with intranet and internet facility on 24X7 basis. The Intranet (Local Area Network) access facility supports both wire and wireless connectivity. The intranet backbone is build up with 3 CISCO manageable (Layer-3) switches and they are interlinked with fiber optic cables. The backbone is supported by 16 layer-2 switches. The wired intranet access provides upto 100 Mbps speed.

A wireless network supporting uninterrupted wireless intranet access to the mobile devices, covers the main building of the centre and guest house. The Wi-fi facility uses high end CISCO wireless access points. Recently CSC extended Wi-fi infrastructure by implementing Wireless Lan Controller (WLC) in intranet.

For the Internet facilities currently CSC leased 2 internet lease lines from 2 different providers. They are as follows -

  • 1.0 Gbps lease line provided by National Knowledge Network (NKN).
  • 15 Mbps lease line provided by Sify Technologies Limited.

3.3 Computational Clusters

For the powerful experiments CSC have 5 computation clusters. Where users can submit their jobs either Parallel or Serial.
