Lab status

Cooling, machines and services for smtornado.com. Served from the VPS, which is outside the lab — so this page stays up when the lab does not.

D5 normally runs; DDC is the optional booster. Compare flow with a commissioned baseline at the same pump duty and pump combination.

Aquacomputer sensors

No Aquacomputer devices are reporting. They are read over USB by the rack controller; if that machine is up and these are absent, the kernel driver has not bound.

GPU temperatures are not collected on this page. They are recorded inside the lab, where the detail belongs; this page keeps to what is needed to answer "is it working". The workstation and the second compute node are expected to be off sometimes — that is not a fault.

Compute queue

The scheduler is not reporting to this page. That does not mean it is down — it means this page has no queue metrics to show.

The dataset links cited in published papers are checked continuously and are answering.

Checked from this server, over the public internet — the same path a visitor takes. Container-level health is monitored inside the lab; what is shown here is whether the service actually answers.

The lab is at the end of a home internet connection and reaches this server over an encrypted link. When this reads stale, the services below may be fine and simply unreachable — which is a different problem from the services being down, and needs a different fix.
