Setting up an account
In order to create your an account on EDI cluster please reach out to Janek and / or Staszek via Slack or e-mail.
You will get a set of two credentials in different e-mail messages.
- First password allows to login to the entry node (jumphost) at
lbs.cent.uw.edu.pl. This password needs to be changed after first login and subsequently in 90 days intervals.
- Second password allows to login to the compute nodes
Please familiarize yourself with the general rules of cluster usage before proceeding further - LINK
Important: in case of lost password or other technical difficulties related to the entry node
(not compute nodes) please reach out to the IT department at CeNT UW - address:
it @ cent.uw.edu.pl.
[sih-61] prefix in the message title and add Janek and Staszek to CC.
Please note that for now password changes on each of the compute nodes and the entry node are not synced.
The centralized authentication system will be introduced in near future.
Connecting via SSH
Connections to the EDI cluster are handled via SSH protocol. See the figure below for a brief introduction of the network organization:
In order to login to the entry node you can issue the following command:
In order to simplify file copying, every day work with e.g. Jupyter notebooks the suggested way of connecting
edi nodes is to use sshuttle. This allows to
bypass the login node and work almost the same way as being connected via VPN to the local network.
sshuttle was installed according to the guide
you can connect as follows:
sshuttle --dns -NHr email@example.com 10.10.61.1/24
During the first connection to the entry node you will be required to change the initially obtained password.
Additionally, depending on your computer and network settings, you may have to connect to
sshuttle so that SSH connections are properly configured.
To avoid putting password during each login you can set up authorization via a certificate - additional information is available here
Each user has access to two personal directories:
The contents of the default directory
/home/users/your_username are unique to each compute node and
they are not available on other nodes.
In order to use distributed file system please
/home/nfs/your_username network mount
(please follow the guidelines).
The recommended options to send or fetch files from EDI cluster are either
The storage on the entry host
lbs.cent.uw.edu.pl is very limited therefore it is recommended to setup
sshuttle to send / fetch files directly.
Assuming you established a connection with
sshuttle you can directly send files or
directories to any
scp file.txt your_username@edi05:
Once the basics are set up you should be able to start running calculations. Follow the next chapter for more details.
