Hydras
The Hydras are virtual based serves hosted in the Campus Cloud. They offer slightly higher stability and are better for smaller computing jobs.
Hardware Specifications
- Intel Xeon CPU
- 12 cores @2.6Ghz
- 64GB-128GB of RAM
- NAS used for /home storage
Ghidorahs
The Ghidorahs are physical servers located throughout Baker Hall. They are designed for lighter GPU jobs.
Hardware Specifications
- Core i9-13900KF CPU
- 8 performance cores @5.4Ghz
- 16 Efficiency cores @4.3Ghz
- 64GB of RAM
- RTX 4090 24GB of video memory
Leviathans
The Leviathans are physical servers located throughout Baker Hall. They are designed for heavy CPU and RAM jobs.
Hardware Specifications
- AMD Ryzen 9 9950x
- 16 cores @5.7Ghz
- 128GB of RAM
- 4TB of local NVME storage
- Mounted at /scratch
- Data stored in this location will only be accessible on the original server.
Storage
Each server's "/home" directory located on the department's NAS. This means your files will be accessible on every server.
The NAS is a total of 100TB. This space is shared and monitored for fair usage. If you store large amounts of data, you may be asked if it is all necessary.
To see available space on the NAS, run the command below in a terminal on the server.
df -h | grep "/home"To see your total usage run the command below. It may take a few minutes to finish
du -sh ~
Using the Servers
Accessing the servers requires using an SSH compatible terminal. Applications such as "Command Prompt" on Windows or "Terminal" on MacOS can achieve this.
To SSH to a server, open either app listed previously and enter the SSH command shown below. Be sure to use your StatDS computing account.
ssh statdsusername@hydra1.stat.cmu.eduIn the line above, replace "hydra1" with the server you want to connect to.
| Hydras | Ghidorahs | Leviathans |
|---|---|---|
| hydra1 | ghidroah1 | leviathan1 |
| hydra2 | ghidorah2 | leviathan2 |
| hydra3 | ghidorah3 | leviathan3 |
| hydra4 | leviathan4 | |
| hydra5 | leviathan5 | |
| hydra6 | leviathan6 | |
