Machine List

Most of our machines are in the E7, F7, G7 and H7 racks (as of Jan. 2022) in the MC 3015 server room. There is an additional rack in the DC 3558 machine room on the third floor. Our office terminals are in the CSC office, in MC 3036/3037.

Web Server

You are highly encouraged to avoid running anything that's not directly related to your CSC webspace on our web server. We have plenty of general-use machines; please use those instead. You can even edit web pages from any other machine--usually the only reason you'd *need* to be on caffeine is for database access.

caffeine

Caffeine is the Computer Science Club's web server. It serves websites, databases for websites, and a large amount of other services.

(Redundant active backup coming soon...)

Specs

• QEMU virtual machine hosted on Teriyaki
  • 32 vCPUs
  • 64GB of RAM

Services

• Club and member web sites with Apache
• MySQL databases
• PostgreSQL databases
• ceo daemon

mathnews

xylitol hosts a systemd-nspawn container which serves as the mathNEWS webserver. It is administered by mathNEWS, as a pilot for providing containers to select groups who have more specialized demands than the general-use infrastructure can meet.

General-Use Servers

These machines can be used for (nearly) anything you like (though be polite and remember that these are shared machines). Recall that when you signed the Machine Usage Agreement, you promised not to use these machines to generate profit (so no cryptocurrency mining).

For computationally-intensive jobs (CPU/memory bound) we recommend running on high-fructose-corn-syrup, carbonated-water, sorbitol, mannitol, or corn-syrup, listed in roughly decreasing order of available resources. For low-intensity interactive jobs, such as IRC clients, we recommend running on neotame. If you have a long-running computationally intensive job, it's good to nice[1] your process, and possibly let syscom know too.

corn-syrup

Dell PowerEdge 2950

Specs

• 2 × Intel Xeon E5405 (2.00 GHz, 4 cores each)
• 32 GB RAM

neotame

neotame is a SuperMicro server funded by MEF. It is the successor to taurine.

• 64GB RAM

Notes

• SSH server also listens on ports 21, 22, 53, 80, 81, 443, 8000, 8080 for your convenience.

mannitol

mannitol is a SuperMicro server funded by MEF. CUDA is available on this node.

Specs

• 2x Intel Xeon E5-2630 v4 processors (2.2 GHz, 10 cores/20 threads each)

Office Terminals

It's possible to SSH into these machines, but we discourage you from trying to use these machines when you're not sitting in front of them. They are bounced at least every time our login manager, lightdm, throws a tantrum (which is several times a day). These are for use inside our physical office.

The Programme Committee has access to a VM on corn-syrup called 'progcom'. They have sudo rights in this VM so they may install and run their own software inside it. This VM should only be accessible by members of progcom or syscom.

The CI/CD stuff for the csclub.uwaterloo.ca runs on this vm (drone).

Codey Bot Only

codey-prod: QEMU virtual machine hosted on Teriyaki

codey-staging, codey-dev: Used to ran on Cloudstack, currently not deployed on Proxmox due to a lack of Codey Bot devs.
