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.
