Access

HPC access instructions

  The following instructions apply to internal NU users, i.e. users with
  a valid nu.edu.kz corporate email address. To create a request please
  follow these instructions:
   1. To open an new account on Shabyt HPC system, the PI of a research
      project (typically a faculty member) should fill out the form in
      [11]ticketing system. Instructions for creating a request in the
      ticketing system can be found [12]here. If there is a need for
      accounts for group members (RAs, students) it should be clearly
      indicated in that form. Note that the form must be filled by the PI
      only, regardless of the fact who the account is for - the PI and/or
      a group member. Group members cannot request accounts by
      themselves.
   2. NU HPC committee will consider the application form and
      approve/reject it based on the information provided.
   3. When the HPC committee approves the application, username/password
      will be communicated to the users by the HPC administrators.
   4. Having the credentials received from the HPC admins, users can
      connect to Shabyt using the SSH (secure shell) protocol. Copying
      files files to/from Shabyt can be done either via SFTP (secure ftp)
      or SCP (secure copy).
   5.  The PI assumes responsibility for the use of the HPC system by
      group members.
   6.  In case if there is a need to add or remove group member accounts
      after the initial setup, the PI should contact HPC admins via email
      ([13]hpcadmin@nu.edu.kz).
  Note: Only connections that originate from the internal campus network
  are allowed at this time. The HPC team will implement a secure
  mechanism for outside connections in the future. Until then the
  out-of-campus users should use VPN (virtual private network) to enable
  connectivity to Shabyt. We recommend using GlobalProtect VPN software
  for this purpose (please contact [14]helpdesk@nu.edu.kz for obtaining
  the software).
  When a user is connected to the campus network via VPN, he/she should
  use an SSH client to establish a connection with the interactive
  login/management node (10.3.64.61). There is a multitude of free and
  powerful third party SSH clients available for any operating systems.
  Windows, Linux, and MacOS all have native SSH clients built directly
  into command line. For a client with a graphical user interface on
  Windows we can recommend PuTTY, which can be downloaded [15]here.
  Windows (PuTTY)
  Download, install, and launch the PuTTY client. Next, in the PuTTY
  configuration window that pops up, enter 10.3.64.61 in the Host Name
  field as shown below

  Make sure the Connection type  field is set to SSH. Then press the
  Open  button. When you connect for the very first time, PuTTY will give
  a security alert. Accept it by pressing Yes.

  Then enter your login and password (use the credential provided by the
  HPC administrators) as requested in the terminal window that will open
  up.

  Windows (PowerShell or Command Prompt)
  Windows PowerShell and Command Prompt provide a built-in SSH client.
  Search for the PowerShell or Cmd app and launch it. Then enter your
  credentials:

  UNIX compatible OS
  Every Linux distribution comes with an OpenSSH client that should be
  installed by default. Thus, there is no need to install any additional
  software packages. Simply locate and launch a Terminal. At the prompt
  of the terminal window enter ssh username@10.3.64.61 (replace username
  with your actual user name). It will ask you for your password. Note
  that you will not see any characters on the screen as you type the
  password. This is normal. When you connect for the very first time you
  will also be prompted to confirm the authenticity of the host. Type yes
  to confirm it. Example below shows the Gnome terminal with an SSH
  program launched:

  such as bash, tcsh, zsh, etc. It allows multiple versions of the same
  software package be installed simultaneously and invoked by simply
  loading a proper module.
  Here is a list of most frequently used terminal commands implemented in
  Environment Modules.
  module avail List all software modules available in the system via
  Environment Modules
  module show <ModuleName> Display information about module file
  module load <ModuleName> Load module into the shell environment
  module unload <ModuleName> Remove module from the shell environment
  module list List currently loaded modules
  module purge Unload all previously loaded modules
  To learn about other commands please type man module in the terminal
  window.
