# Compute instances

## How to display GPUs available?

On the Compute page, you'll find a list of all our available instances, sorted by model and number of GPUs. Filters are available to help you find the right offer for your needs: [**read this tutorial to know which offer you should choose according to your workload and use case!**](/tutorials/which-compute-instance-for-ai-models-training-and-inference.md)

## Pods characteristics

<table><thead><tr><th width="263">Characteristics</th><th>Definition</th></tr></thead><tbody><tr><td>vRAM</td><td>Virtual Random Access Memory: The amount of memory allocated to a virtual machine for its operations, functioning similarly to physical RAM in a physical machine.</td></tr><tr><td>Memory in GB</td><td>The total amount of memory available for use in a system, typically measured in gigabytes (GB), which can be used for running applications and processes.</td></tr><tr><td>vCPU</td><td>Virtual Central Processing Unit: An abstraction of physical CPU cores, allocated to virtual machines to handle computational tasks.</td></tr><tr><td>Storage</td><td>The space available for storing data, applications, and system files, measured in gigabytes (GB) or terabytes (TB).</td></tr><tr><td>NVLink</td><td><p>A high-speed interconnect technology developed by NVIDIA to enable fast communication between GPUs, and between GPUs and CPUs, for improved performance and efficiency in </p><p>computational tasks.</p></td></tr></tbody></table>

<summary>⚠️ The Storage of your Pod is non persistent. </summary>

It means that it will only host your data during the instance. Then, if you haven't subscribed to a volume, your dataset will be deleted. Learn [**how to get a volume in Sesterce Cloud!**](#how-to-get-a-volume)

</details>

## How to select my Pod?

Through “GPU” and “Specs” tabs, you can display information corresponding to each Pod. Please find above the corresponding definitions. Then, you can click “launch”!

## I need a persistent storage!

If you need a persistent storage to store your dataset at the end of your instance, you can thick the appropriate checkbox to display only Pods for which the persistent storage is available.

<summary>Please consider those rules for Volumes management. <a href="/pages/DanaahABEKYGhBuMui5q">See dedicated documentation here. </a></summary>

* Volumes should be hosted **in the same Cloud** and **region** as Pod selected
* Once created, volume size can be increased but not decreased, to preserve your data
* A single volume can contain several datasets, but **it is not possible to link a single Pod with more than one Volume**.
* It is **not possible** to link a persistent storage to an instance **already created**.

</details>

{% hint style="success" %}
According to the Pod you'll choose, you will have the possibility to create a volume directly from the launching path, hosted in the appropriate cloud & region.
{% endhint %}

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```

```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
