High Performance Computing HPC and Activities of Computer Centre, IIT Kanpur

3. CC@IITK has a glorious history This centre was established in 1964 and it was started in Western Labs under Department of Electrical Engineering. It moved to its present building in 1969, when it was recognized as an independent department in the Institute. IBM-1620 was the first Computer acquired by IIT Kanpur. Next was IBM-7044 in 1966, followed by an IBM-1401. Several specialized Computers such as IBM-1800, PDP-1 etc were added in subsequent years. The next major upgrade was the addition of DEC-1090 mainframe computer in 1979, which was the first sharing computer of IIT Kanpur. This was first computer which had terminals. In 1989, CC purchased Super minicomputers of HP 9000 series.

4. History of Computer Centre In 1987, the first PC lab was setup providing DOS environment. Convex 220 was setup in 1990. CC got its Mini Supercomputer IBM SP2 was setup in 1999. First parallel computer Email service was run under Ernet project in early 1990s and was subsequently moved to computer centre around 1994 In 1995 the Campus Network was upgraded to 100 Mbps Fiber Backbone and 10 Mbps UTP Access Network. 64 Kbps Internet link was setup in 1998 and today the bandwidth has increased to more than 1 Gbps. Linux Cluster (SUN & HP) set up in 2004-05

6. Facilities Provided by CC Computer Center provides state-of-the-art Computing, E-mail, Internet and other facilities 24 hours a day and 365 days a year for more than 7500 users. Major facilities provided by CC are: Computing hardware Application software Campus Network Email and Internet Linux and Windows Labs File Storage and Backup Services Hosting of IITK website Office Automation (under DD) Technical support via phone and email Maintenance of PCs and peripherals

7. Activities 4-5 hours of Classes for UG and PG per day at CC Students work on computing and CAD assignments using CC Lab facilities User training / Education / Familiarization / Help with compilation coding etc. Workshops and Seminars Troubleshooting Research and Related Activity Maintenance of Hardware and Software Software installation and upgradation Development and Installation of regularly used software (in-house) Mass User registration / authentication and login id distribution for support Support for Alumni Office, DRPG Lists, Office Automation, OARS, Regular Courses Mailing, Conferences, Short Term Courses, Mass Internal Mailing and announcements, NO Dues, supply and repair of PCs for administration and other sections, web hosting Security Mail, Domain Name Service, Networking, Software Downloads sites, Mirror Site maintenance

8. Computing Facility Computer Centre has 3 4-CPU master nodes and 146 dual-CPU compute nodes in the Cluster amounting to 292 cores of computing power connected over 1Gbps LAN.  Applications - Gaussian, Linda, Charmm, FEM, Diff.Equ. Solving Molpro, parallel libraries etc.

9. Storage and Backup Storage One 33 TB HP Storage Works EVA8000 Enterprise Virtual Array and One 6TB SUN StorEdge 6120 File Service One HP Storage Works Clustered File Systems (Poly Serve Symmetric Cluster File System) and One Virtual File Service (PolyServe Matrix Server) Backup Service One Backup Server for Users' home directories and Users' Mail with HP MSL6000 DP Backup Policy: Daily incremental backup, saved for one week, Weekly incremental backup, saved for one Month and Monthly full backup, saved for one year.

10. Linux and Windows Environment Linux Working Environment Three Labs equipped with 143 Latest Configuration PC with Ubuntu and Fedora. 9 Computational Servers. Software Installed for Simulations and Modelling, Optimization etc. Windows Working Environment Domain Controller and License Server, SAMBA Server and Deployment Server Two Labs equipped with 75 Latest Configuration PCs Software Installed in wide category

11. Email Setup Approximately 7500 mail boxes Quota ranging from 500MB to 1500 MB Around 250000 Mails sent and received every day out of which 90% of incoming mail is SPAM which is filtered by Barracuda SPAM firewall Both Linux Postfix and Microsoft Exchange platforms provided The setup is state-of-the art enterprise class providing high availability and fault tolerance.

12. Email Architecture

13. Current Network Setup Institute Gigabit LAN (Local Area Network) with more than 15000 nodes covering Academic Area and Student Hostels. 2 Core Switches, ~50 Distribution Switches, ~800 Access Switches Gigabit Fiber Optic Backbone Network with more than 21 Kms of Fiber laid in the Campus Fully Managed Network 1 Gbps Internet Bandwidth from Airtel Backup Bandwidth from Reliance and NKN Overlay Wi-Fi Network in the Academic Area ~500 Access Points Internet Application Servers for providing Web, Mail, Proxy, DNS and other Internet services to the users.

14. Network Architecture

15. Network: Immediate and Long Term Plans Immediate Plans: Expand the network to accommodate new buildings/ facilities and increasing student strength Provide 1 Gbps LAN in the residential area Long Term Plans: Build an All IP Network to provide integrated Voice-Video-Data network Provide IP based Voice/Video phones and Desktop Conferencing facility

16. Cyber Security In view of the requirement to strengthen the Cyber Security, following steps have been taken in the recent past: All the switches have been replaced with managed switches. This allows binding an IP address with every network port which helps in tracing the machine/individual who has been involved in any hacking. A CCTV IP camera has been installed at the entrance of CC to record the entry and exit of users. A Fortigate UTM (Unified Threat Management) device has been installed at the Internet Gateway to monitor and control the Internet Traffic and allow tighter control on the traffic to Internet Application Servers for better security.

17. Measures to Improve Cyber Security Block all the unused TCP/UDP ports for Internet Application Servers on the Internet Gateway Firewall. Implement electronic Access Control based on identity in all CC labs. In addition, install CC Camera in all the labs. Implement DHCP based IP address allocation policy. A machine should be able to use the network only if it has been allocated IP address through DHCP. Implement Network authentication for both wired and wireless network. Make provision for issuing temporary ids for visitors. Implement Wireless Intrusion Detection and Prevention system. Implement more secure authentication than currently followed scheme. Implement better security for system logs on the individual servers. This will help trace the attack.

18. Activities Underway Windows and Linux Labs for more than 200 users in New Core Building Gigabit LAN connectivity in Residences New Mail Storage (25 TB) New UPS (900 KVA) GPU servers and high end workstations New HPC facility
