Sol is Lehigh's newest Linux cluster replacing Corona and other ancillary Level 2 resources. Following our tradition of naming high performance computing clusters after stars or celestial phenomena, Sol is named after the nearest star.star.

Sol is a heterogeneous cluster launched on Oct 1, 2016 with a total of 34 nodes, 26 are Condo investments by two CAS faculty. All nodes provide 500GB scratch storage for running jobs and are interconnected with 2:1 oversubscribed EDR (100Gbps) Infiniband fabric. In Fall 2018, a new Ceph storage cluster was installed that provides a 11TB CephFS global scratch space for storing temporary data for 7 days after completion of jobs.

System Configuration
| Expand | ||
|---|---|---|

|
...
| Code Block | ||
|---|---|---|
| ||
ssh username@sol.cc.lehigh.edu |
If you are off campus, then there are two options
- Start a vpn session and then login to Sol using the ssh command above
- Use ssh gateway as a jump host first and then login to Sol using the above ssh command on the ssh gateway prompt. If your ssh is from the latest version of openssh, then you can use the following command
| Code Block | ||
|---|---|---|
| ||
ssh -J username@ssh.cc.lehigh.edu username@sol.cc.lehigh.edu |
If you are using the ssh gateway, you might want to add the following to your ${HOME}/.ssh/config file on your local system
| Code Block | ||
|---|---|---|
| ||
Host *ssh HostName ssh.cc.lehigh.edu Port 22 # This is an example - replace alp514 with your Lehigh ID User alp514 Host *sol HostName sol.cc.lehigh.edu Port 22 User <LehighID> ProxyCommand ssh ssh nc %h %p |
to simplify the ssh and scp (for file transfer) command. You will be prompted for your password twice - first for ssh and then for sol
| Code Block | ||
|---|---|---|
| ||
ssh sol scp sol:<path to source directory>/filename <path to destination directory>/filename |
If you are using public key authentication, please add a passphrase to your key. Passwordless authentication is a security risk. Use ssh-agent and ssh-add to manage your public keys. See https://kb.iu.edu/d/aeww for details.
Windows users will need to install a SSH Client to access Sol. Lehigh Research Computing recommends MobaXterm since it can be configured to use the SSH Gateway as jump host. DUO Authentication is activated for faculty and staff on the SSH Gateway. If a window pops up for password enter your Lehigh password. The second pop up is for DUO, it only says DUO Login. Enter 1 for Push to DUO or 2 for call to registered phone.
