MUHACK CPU SERVER
A shared machine that gives all members access to personal VM/LXC for general purpose computations.
What this box is for
- General computational needs
Hardware
- CPU : 36 x Intel(R) Xeon(R) CPU E5-2696 v3 @ 2.30GHz (1 Socket)
- RAM : 64 GB ECC DDR4 @ 2400 Mhz
- GPU-A : NVIDIA GK208B [GeForce GT 710]
- Disks : SSD 256GB - 6TB Raid0 (3+3 HDD)
- NICs : Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
Software stack
- Proxmox VE 8.x (kernel 6.8)
Getting your own environment
- Make sure your laptop/PC is connected to the MuHack Tailscale tail-net and can ping gpu.muhack.
- Go to the proxmox login page and login a first time to create your account and then logout immediately
- Talk to any sysadmin (email or in person on Tuesday). Tell us
- what you plan to run
- an estimate of how much RAM / runtime you’ll need
- We’ll create a container (or VM) for you and hand back:
- ID (e.g. ct104 or vm203)
- a random initial password
Typical turnaround time: usually same day or next-day. However might take more time if the sysadmins are busy.
After the first login you have to re-login a second time to let proxmox setup correctly your account's group
At this point you have two options for interact with the console:
- Use the proxmox web interface's integrated console
- Join the machine to a tailnet (your personal or the MuHack's one) and connect trough SSH -> remember to enable ssh root access within sshd config file!
- Jobs longer than 12 h → announce them at the Tuesday meeting or in the telegram channel.
- Sysadmins may pause/stop workloads that block others
- Crypto-mining strictly forbidden
Good-citizen checklist
- If don't need to keep you VM/LXC up, shut it down for others: the resources are limited and shared!
- Keep /tmp and your home directory tidy; disk space is shared
- BACK UP YOUR OWN DATA: we have no data persistency or backup guarantee
