CCI maintains a compute environment to support class requirements. Typically referred to as Tux, this environment provides various services, which are described below.
- The primary way of working with Tux is to log in to one of the Tux nodes. These nodes, numbered tux2 through tux4 (tux1 is reserved for management and testing), are virtual machines with 60 GB of RAM and 30 CPU cores. The underlying hypervisor runs on AMD Epyc CPUs.
- Tux supports logins over SSH or Remote Desktop. For more information on accessing your account and logging in, please visit the page Tux Account Information.
- Tux storage lives on the college's CEPH cluster, which provides 150TB of shared storage, including Tux file storage and space for virtual machines in the college's virtualization environments. Each Tux user is allocated 4GB of storage, and more storage can be requested for approved use cases. To request more storage, please contact email@example.com and include your username, how much space you need, and what the storage will be used for.
- Starting in Spring 2023, Tux is moving to Drexel authentication. This will simplify logins and password resets, as users will no longer have two separate accounts.
- Legacy Tux accounts are separate from Drexel credentials, and more information on getting your account can be found at Tux Account Information. These accounts are still being created for new users in Spring 2023, but should only be used for Gitlab logins.
- CCI hosts a Git server, accessible to all CCI students, faculty, and staff. There is a limit of 10 personal projects set by default, but users may request an increase by sending a message to firstname.lastname@example.org explaining the need for more projects.
- Gitlab projects include an Issues board, which can be used for project management, planning, and task management. If the project is shared with multiple users, each user can contribute to the board. Custom labels and milestones can be set on a per-project basis. Gitlab projects also include a Wiki section for documentation.
Float and Double
- Float and Double are the college's shared GPU workstations, which are part of the Tux ecosystem. Each node has 32GB of RAM, 8 CPU cores (virtualized AMD Epyc cores), and an NVIDIA Tesla T4 GPU. Students, faculty and staff are welcome to use these resources as needed, but please keep in mind that these are shared resources. If a process is found to be preventing others from using the system, we reserve the right to contact the user(s) who are running those processes and request that they be stopped so others can use the system.
- Float and Double can be reached by SSH. Use the same instructions as connecting to Tux over SSH(Tux Account Information), but replace "tux.cs.drexel.edu" with "float.cs.drexel.edu" or "double.cs.drexel.edu".
- All CCI students, faculty, and staff have access to an Apache web server. Files are served from the folder "public_html" in your user folder on Tux, and the sites can be seen at https://www.cs.drexel.edu/~(your username). Permissions for this folder (and all subfolders) should be set to 755 (eg, chmod -R 755 public_html). This will allow all users to read the contents of the directory and all subfolders.
- More Web technologies available as part of the Tux ecosystem can be found at Tux Web Services.
