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 thread Intel Xeon CPU E5-2696 v3 @ 2.30GHz (1 Socket)
  • RAM: 128 Gb ECC DDR4 @ 2133 Mhz
  • GPUs:
    • NVIDIA GeForce GT 710 — emergency host console only
  • Storage:
    • OS drive: 256 Gb SATA SSD
    • Storage (SSD): 3*1Tb Exceria SSD RAID-Z1 (2Tb usable)
    • Storage (HDD): 2*3Tb Toshiba P300 HDD ZFS striped (6Tb usable)
  • NIC: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
  • KVM: PicoKVM PCIe

Software stack

  • Proxmox VE 8.x (kernel 6.8)

Getting your own environment

  1. Make sure your laptop/PC is connected to the MuHack Tailscale tail-net and can ping gpu.muhack.
  2. Go to the proxmox login page and login a first time to create your account and then logout immediately
  3. Talk to any sysadmin (email or in person on Tuesday). Tell us
    1. what you plan to run
    2. an estimate of how much RAM / runtime you’ll need
  4. We’ll create a container (or VM) for you and hand back:
    1. ID (e.g. ct104 or vm203)
    2. 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:

  1. Use the proxmox web interface's integrated console
  2. 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!

Fair-share policy

  • 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

Questions / ideas → email superusers (see info table at the top) — or just grab us at the Tuesday MuHack meeting.
