Computational Resources

IEOR has several computational servers available to students and faculty for their research and other academic activities. These machines are named after localities in Mumbai. They have the following configurations.

Machine Name IP Address CPU  Number of Cores RAM (GB)
passpoli 10.119.2.11 AMD Opteron(TM) Processor 6212 4 32
saki 10.119.2.12 Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz 20 128
tunga 10.119.2.13 Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz 20 128
kanjur 10.119.2.14 Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz 20 128
tirandaz 10.119.2.15 Intel(R) Xeon(R) CPU E5506 @2.13GHz 4 64

To view the load on the servers, click here. All these servers run Debian 8.1 "Jessie " operating sytem. They can be used to run the following software.

  • AnyLogic
  • AMPL
  • ILOG CPLEX Optimization Suites
  • R
  • Gurobi
  • MATHEMATICA
  • GIMP
  • Polymake
  • maple
  • Eclipse
  • sage
  • Scilab

Besides these software, several standard linux utilities including compilers, debuggers, version control software,  etc. are also available. Additional software can be installed on request.

Web Server

Our web server Powai is an Intel-i7, 4-core, 32GB, 1TB machine. Its IP address is  10.119.2.10.

How to Access a Server using SecureShell (SSH)

All the above mentioned machines are accessible to all faculty and students of IEOR. Other interested members of IIT-B community may also request access to these servers. The users may log in by means of ssh. IIT Bombay LDAP identity and password would be required for authentication.

On Windows

PuTTY, WinScp or SSH SecureShellClient can be used in Windows OS to connect to the server. 

1. First download PuTTY from this link.
2. Next, configure PuTTY. Fill in server info in the Host Name (or IP Address) and Port fields. Type a name in the Saved Sessions field and click Save if you want to save this session info for quick reconnecting.

3. Now connect to the desired server by clicking Open. Input your username and password

On Linux

SSH ("Secure SHell") is a protocol for securely accessing one computer from another. Despite the name, SSH allows you to run command line and graphical programs, transfer files, and even create secure virtual private networks over the Internet.

1.  For installing the open SSH client & server we should give the command in the terminal window. In Ubuntu and other distributions, openssh-client is installed by default. openssh-client is required to run ssh from your computer. If you want to access your computer through ssh from some where else, then install openssh-server.

      >>>   sudo apt-get install openssh-client openssh-server

2. Once it is installed, we can open a terminal and type
>>> ssh username@ip_address
or
>>> ssh -l username ip_address

 3. Then enter your password and it is ready to use.
 4. If you want to use graphical windows after you log in, then you need to use -Y and -X options while logging in.
>>> ssh -X -Y username@ip_address

For more options type "man ssh" in any linux termminal.

On Mac

Mac OS has a built-in SSH client called Terminal which can be used to connect to remote servers. By default, Terminal.app is located in Applications > Utilities folder. Double-click on the icon to start the client.

Using Terminal for SSH

At the prompt type:
>>> ssh username@hostname
​where username is your LDAP username and hostname is the hostname of the server you are trying to connect to. For example, if user jafeerh wants to connect to Tirandaz server, he should type:
>>> ssh jafeerh@10.105.27.97
