OpenSARLab Environment¶
Operating System¶
- Ubuntu 22.04.4 LTS
Server Profiles¶
Every OpenSARLab user has access to a JupyterHub server running on an AWS EC2 instance. Users may select from two server profiles offering varying amounts of compute resources to support different workloads.
m6a.large:
- RAM Guarantee: 5G
- RAM limit: 8G
- CPU limit: 2
m6a.xlarge:
- RAM Guarantee: 10G
- RAM limit: 16G
- CPU limit: 4
Volume (storage)¶
- *500GB of EBS volume storage per user.
OpenSARLab uses Amazon AWS EBS volumes mounted on user servers’ home directories for persistent storage.
- If a volume is full when a user shuts down their server, it will trigger an
out-of-storage exceptionthat will prevent users from starting a server again.- Please contact an OpenScienceLab administrator if this occurs.
Privileges¶
- Users do not have
root(i.e.,sudo) privileges. - Users have read/write access in their local directories on their EBS volumes, but limited write access in their root directories.
