Getting Started

The computing server is based on linux operating system. You will need to know some fundamentals to get started with the server.

I will help with maintaining the basic functionalities of the server and granting basic access to you. You will need to figure out how to perform your own computing tasks under the regulations stated in this documentation.

Quick Start

After you cantact the administrator and provided a username, you will be granted an account on the server. You will then need a computer that is connected to the departmental network with network cable to access the server.

Then you can login to the server using the following command:

# Login 
ssh <username>@dream   

# Your personal data directory
/data/people/<username> # on HDD

# Your project data directory
/data/project/<projectname> # on HDD

# Your home directory
/home/<username> # on SSD, limited space

Service Provided

  1. CUDA 12.4
  2. GPU task spooler. A spooling system that helps manage CPU/GPU tasks easily. You can think of SLURM but for small individual servers rather than high-performance clusters.
  3. Docker. Provided upon request.
  4. TigerVNC. (coming soon) Provided upon request.
  5. Conda. Provided upon request. It is okay if you want to install it to your home directory.
  6. MATLAB. (coming soon)

Rules

This is a shared server. Please follow the rules to ensure everyone can use the server smoothly.
  1. Extensive computing tasks should be submitted using the job management software ts, and should never be run on the login node.
  2. If your task is not queued and consuming significant amount of resources or put the server at risk, it will be terminated without prior or further notice.
  3. You should keep your own data safe and secure by granting minimal access to your data.
  4. Symbolic links is recommended to avoid accidental or subjective data loss.
  5. Before trying to install a large or complicate software, you should try to use it by docker, as this will save all of us lots of time.
  6. If you indeed need the root access. You should prepare a detailed installation guide for the administrator to review and proceed.
