Code01.Fit.Edu

Introduction

The code01.fit.edu server allows students, faculty, and staff to run research and academic tasks in a non-clustered environment.

Its purpose is to provide a learning and research platform to users, and consists of 8 Intel Xeon 6242 (16-core) 2.80GHz processors and 32 GB of RAM. It allows X11 Forwarding, which allows any installed X Windows applications to be displayed on the user's local workstation desktop.

How to access it?

To access the code01.fit.edu shell, SSH to the server address (code01.fit.edu) and use your TRACKS account and password to log in. Also, this provides another means of access to your UDrive documents. SFTP is used to copy files to and from your UDrive if the Windows File Share (udrive.fit.edu) is unaccessible. How to use SSH and SFTP to Code01

Environment Modules

Environment Modules is a software environment management system which allows multiple versions of packages to be available to users.

Common commands

  • module avail - to list available modules. Modules with (default) will be loaded if a version is not specified.
  • module load - to load a module.
  • module unload - to unload a module.
  • module list - to list loaded modules.

Examples - Using Python and Pip with Environment Modules

Several versions of Python are available using Environment Modules, in addition to the default package versions. You can determine what version is available by appending the --version switch to your python command.

NOTE: By default the command "python" runs the Python 2.x interpreter and the command "python3" runs the Python 3.x interpreter.

Python example:
  • List current modules.
    ~ $ module list
    No Modulefiles Currently Loaded.
  • Show current Python and Python3 versions. Since no Python modules are loaded, they are the OS provided versions.
    ~ $ python --version
    Python 2.7.5
    ~ $
    ~ $ python3 --version
    Python 3.4.5
  • List available Python modules. Default module is indicated with (default).
    ~ $ module avail python
    ------------------------------------------ /opt/software/modules/------------------------------------------
    python/2.7.9 python/3.4.2 python/3.5.1(default)
  • Load default Python module.
    ~ $ module load python
  • Show Python and Python3 versions. Since only the Python 3.5.1 module was loaded, it was the only version that changed.
    ~ $ python --version
    Python 2.7.5
    ~ $
    ~ $ python3 --version
    Python 3.5.1
  • Unload Python module.
    ~ $ module unload python

Pip can also be used with python to install python packages. Virtualenv is available to isolate your packages.

As with Python, pip has different commands for different versions:

  • pip, pip2, and pip2.7 - to install OS maintained Python 2.7 pip packages, or a Python 2.7.x module if loaded.
  • pip3 - to install OS maintained Python 3.4 pip packages.
  • pip3.4 - to install OS maintained Python 3.4 pip packages, or a Python 3.4 version python module is loaded.
  • pip3.5 - to install Python 3.5 pip packages, if a Python 3.5.x module has been loaded.
Pip examples:
  • List current modules.
    ~ $ module list
    No Modulefiles Currently Loaded.
  • Display pip3 and pip3.4 versions. With no Python modules loaded, they use the OS provided version.
    ~ $ pip3 --version
    pip 9.0.1 from /usr/lib/python3.4/site-packages (python 3.4)
    ~ $
    ~ $ pip3.4 --version
    pip 9.0.1 from /usr/lib/python3.4/site-packages (python 3.4)
  • Load Python 3.4.2 specific module.
    ~ $ module load python/3.4.2
  • Display pip3 and pip3.4 versions. Now they show the version from the loaded Python 3.4.2 module.
    ~ $ pip3 --version
    ~ $
    ~ $ pip3.4 --version
    pip 9.0.1 from /opt/software/python/python-3.4.2/lib/python3.4/site-packages (python 3.4)
  • Display the pip3.5 version. Since a Python 3.5 module is not loaded, the command fails.
    ~ $ pip3.5 --version
    -bash: pip3.5: command not found
  • Unload Python 3.4.2
    ~ $ module unload python/3.4.2
  • Load the default python module, which currently is Python 3.5.1.
    ~ $ module load python
  • Display the pip3 and pip3.5 versions. Now they show the version from the loaded 3.5.1 Python module.
    ~ $ pip3 --version
    pip 9.0.1 from /opt/software/python/python-3.5.1/lib/python3.5/site-packages (python 3.5)
    ~ $
    ~ $ pip3.5 --version
    pip 9.0.1 from /opt/software/python/python-3.5.1/lib/python3.5/site-packages (python 3.5)
  • Install a pip module into your userspace. Be sure to specify the version of Pip you want to use.
    ~ $ pip3.5 install --user
