Launch a GPU session

Once you have credits, click Launch GPU-Native Desktop and choose a GPU profile — your Linux desktop opens in the browser.

GPU profiles

Profile	GPUs	Burn rate	Good for
Small	1	1×	Notebooks, analysis, light viz
Medium	2	2×	Multi-GPU experiments, bigger models
Large	4	4×	Training, large simulations
Max	8	8×	Heavy multi-GPU workloads

Billing scales with GPU count

Usage is billed as wall-clock minutes × GPU count, including idle time while the tab is open. A Max session burns 8× faster than a Small one. Pick the smallest profile that fits your workload.

Launching

Pick a GPU profile

The profile picker on the launch page lists Small, Medium, Large, and Max with a burn-rate hint. Pick what your workload needs.

Click 'Launch GPU-Native Desktop'

The button triggers a session claim. If enough GPUs are free, the desktop starts immediately. If not, you're queued — the page shows your position and the reason.

Your desktop opens in the browser

A full XFCE Linux desktop streams into the tab. See Your desktop & tools.

Resuming a saved desktop

If you previously detached or your session was paused, the launch page shows a "Your desktop is saved" resume panel. You can re-launch it (with the same GPU profile) or start fresh.

If GPUs are busy: the queue

When not enough GPUs are free the request joins a fair queue instead of failing:

The queue is FIFO but schedulability-aware — a large request that can't run yet doesn't block smaller requests that can.
Your position and reason are shown ("insufficient free GPUs for requested profile").
Your session starts automatically when GPUs free up.

You can leave the queue at any time.

Billing during a session

While your session is active, the browser sends periodic heartbeats. Each heartbeat deducts elapsed minutes × GPU count from your balance. You see the running timer in the page footer.

When your balance runs out:

Grace period (~2 hours) — the desktop stays up with billing paused so you can top up.
Grace expires — the desktop is shut down and GPUs released, but your files are saved.
Top up and relaunch — your persistent volume is remounted and you continue from where you left off.

Detach vs. End session

Action	What happens
Detach (disconnect button in the control bar)	Returns to the home page. Desktop keeps running. Minutes keep counting.
End session (power button in control bar)	Stops the desktop immediately, releases GPUs, stops billing, saves your files.
Close the tab	Same as End session — the session is released.

Detach is not a pause

Detaching returns you to the launch page but the GPU session remains active and credits continue to tick down. Only End session (or closing the tab) stops the clock.
