Neon shutdown
The Neon HPC cluster will be shutdown on January 7, 2019. Working Neon nodes will be integrated into Argon and accessible as of January 21, 2019. This means that the data from your Neon home/scratch must be migrated either to your existing Argon storage or locally. Below you can find a timeline of the transition:
...
As users will be unable to long into Neon after January 7, 2019, we recommend that users utilize data.hpc.uiowa.edu to transfer stored data rather than relying on mounting their home accounts directly. This will be the new method of mounting Argon home accounts moving forward due to underlying changes in how home storage space will be provided.
The easiest method will be to mount your HPC directories with CIFS via data.hpc.uiowa.edu. You can use this server which allows you to access your neon-home and neon-nfsscratch. This alleviates the need to use a third party program. No HawkID is needed and you can enter the path as seen in the table below. Argon and Neon are both mounted in the same way.
Windows: \\data.hpc.uiowa.edu\
Mac: smb://data.hpc.uiowa.edu
Note that Windows will use backslashes, while Mac will use forward slashes.
| /<cluster>_scratch | Your HPC scratch directory. For <cluster>, this is either "neon" or "argon" |
| /<cluster>_home | Your HPC home directory. For <cluster>, this is either "neon" or "argon" |
Windows
Mac
Same thing as above, but for Mac. You can mount network drives on Mac by going to your desktop and hitting command (⌘) + K.
Third-party programs
Fetch, WinSCP and GridFTP will all also connect to the server data.hpc.uiowa.edu. Refer to the table below to choose the storage path that pertains to you. . Note that this is different than via the CIFS method above.
| /hpchomes/<cluster>/<hawkid>/ | Your HPC home directory. For <cluster>, this is either "neon" or "argon" |
| /Dedicated/<sharename>/ | Dedicated shares |
| /Shared/<sharename>/ | Shared shares |
| /nfsscratch/<cluster>/ | The NFS scratch filesystem. For <cluster>, this is either "neon" or "argon" |
Mounting data.hpc.uiowa.edu (Windows)
You can use this server which allows you to access your neon-home and neon-nfsscratch. This alleviates the need to use a third party program. No HawkID is needed and you can enter the path exactly as seen below.
Note the use of the backward slashes.
Mounting data.hpc.uiowa.edu (Mac)
Same thing as above, but for Mac. You can mount network drives on Mac by going to your desktop and hitting command (⌘) + K.
Fetch (mac only): This will mount your Neon account. Follow the table above for setting a path to get your data from shared shares, dedicated shares, or from nfsscratch. In this case, the path below is just for home directories. You can then execute "get" commands to pull your data from Neon onto your local workstation (keep in mind data is compressed). If you are doing this off campus (or not connected to the VPN), ensure that the "port" is 40. Note that this will require a Duo authentication and you should see notification on your default device.
WinSCP (windows only): This will mount your Neon account. Follow the table above for setting a path to get your data from shared shares, dedicated shares, or from nfsscratch. In the example below, the path is for home directories. The server will be data.hpc.uiowa.edu - we have to manually link it to the proper directory. Once connected, you can drag and drop files from Neon onto your local workstation. If you are doing this off campus (or not connected to the VPN), use port 40.
After you authenticate with Duo, you will notice your path looks like this. Click the very first character, the forward slash, twice. It will open a "Open directory window" where you then can then enter the path from the above table for dedicated, shared, or nfsscratch.
