The following is a list of Linux machines available for students, faculty, researchers, or staff. These Linux machines can be accessed remotely via ssh, scp or VNC.

If you're working remotely, although you are welcome to log into any of our Linux clients, it's recommended that you try ugradx.cs.jhu.edu first, as it can handle more concurrent use than any of the lab machines. All of the systems are identically configured, however, so anything you can do on one of them can be done on all of the others, too.

NOTES

  • All Ugrad Net systems end with .cs.jhu.edu as in, ugrad1.cs.jhu.edu
  • Accounts, mail, web, and home directories on the Ugrad Net machines are different than those on the Grad systems.
  • Ugrad Net linux clients have disk quotas on the Ugrad home directories.
  • If you are unable to reach one of the systems below, please first see if it is part of an outage by visiting our Notices page, otherwise, please contact support@cs.jhu.edu
  • These Linux clients are primarily used for educational (coursework) purposes. Therefore, since you are sharing these systems (CPU, memory, etc.) with other users, please make sure that you do not overload the processors on these systems. When your are completed running your processes, please make sure you stop those processes.


Available Ugrad Linux Systems

  • ugrad1 through ugrad24
    • standard Fedora 38 Linux clients
    • split between both CS Undergraduate Labs (Malone 122 and G61.)
    • Each client has 8 cores (one 4-core i7 CPU with hyperthreading) and 16 GiB RAM.
    • Each system includes an NVIDIA-based GPU that may be used with CUDA and OpenCL (already installed) for coursework.
    • These systems are also available remotely via SSH for logins or scp for secure file transfers.
    • NOTE: From June 5, 2024 through August 6, 2024, ugrad1 through ugrad12 will only be available remotely, via ssh.
  • ugradx
    • Fedora 38 Linux-based compute server.
    • 24 cores (two 64-bit 6-core CPUs with hyperthreading), 288 GiB RAM
    • only available remotely via SSH for logins or scp for secure file transfers.
  • ugradz
    • Fedora 38 Linux-based compute server.
    • 32 CPU cores, 48 GiB RAM.
    • Only available remotely via SSH for logins or scp for secure file transfers.
    • Only accessible from the Hopkins network or VPN; not accessible directly from the Internet.


ssh key fingerprints for these machines can be found on the SSH Key Fingerprints for Grad and Ugrad Net Linux Computers page
