SpaceBots cluster

Hardware

This cluster comprises currently two servers installed at Taguspark campus with the following specs:

• DELL PowerEdge R750XA Server
• 2 x Intel® Xeon® Gold 6330 2GHz
• 1TB RAM
• 8 x 960GB SSD
• 4 x NVIDIA Ampere A100

Software

The servers are accessible through an OpenStack interface, on top of which VM instances are created and managed, together with storage and networking.

Link: https://vmcloud.tecnico.ulisboa.pt/

Instances have by default an ephemeral filesystem mounted in /mnt, which access is faster than the main filesystem, but is destroyed when the instance is deleted.
