Cluster DEI is a computing platform. It consists of many nodes with different hardware:
Some technical details about the GPUs:
| Model | Memory size | Cuda Cores | Tensor Cores | Theoretical Performance |
|---|---|---|---|---|
| Nvidia A40 x 31 | 48GB | 10752 | 336 | 37.42 TFLOPS |
| Nvidia Geforce RTX 3090 x 13 | 24GB | 10496 | 328 | 35.58 TFLOPS |
| Nvidia Quadro P2000 x 3 | 5GB | 1024 | none | 3.031 TFLOPS |
Access to the computing resources is regulated through the Slurm scheduler. You can learn how to use it and successfully submit jobs in the following chapters of this guide.
In order to submit a job to the cluster, connect via ssh at login.dei.unipd.it using DEI credentials. If you don't have a DEI account you can go to https://www.dei.unipd.it/account or https://www.dei.unipd.it/en/account (English version) in order to get one.
As an example, to connect to the login server open a terminal and input the following line:
ssh deiuser@login.dei.unipd.it
where deiuser is the username of your DEI account.
Or, to open a graphical session:
ssh -X deiuser@login.dei.unipd.it
Please note
The system is equipped with some software managed by the administrators. The software catalog can be extended by:
- requesting the installation of some software system wide, if the software is considered useful for a large group of users, by using the DEI Helpdesk System;
- installing your software inside a Singularity container (take a look at the dedicated chapters of this guide).
