Can you remove me from the Scholar mailing list?

Your subscription in the Scholar mailing list is tied to your account on Scholar. If you are no longer using your account on Scholar, your account can be deleted from the My Accounts page. Hover over the resource you wish to remove yourself from and click the red 'X' button. Your account and mailing list subscription will be removed overnight. Be sure to make a copy of any data you wish to keep first.

How is Scholar different than other Community Clusters?

Scholar differs from other Community Clusters in many significant aspects:

• Scholar is a hybrid cluster for teaching courses that require high-performance computing.
• A subset of Scholar front-ends contain Nvidia Tesla V100 accelerator cards. You can access these front ends by logging in to gpu.scholar.rcac.purdue.edu.
• A subset of Scholar compute nodes contain Nvidia Tesla V100 accelerator cards which can significantly improve performance of compute-intensive workloads. These can be utilized by submitting jobs to the gpu queue (add -A gpu to your job submission command).
• A selection of GPU-enabled application containers from the Nvidia GPU Cloud (NGC) collection is installed.

Do I need to do anything to my firewall to access Scholar?

No firewall changes are needed to access Scholar. However, to access data through Network Drives (i.e., CIFS, "Z: Drive"), you must be on a Purdue campus network or connected through VPN.

Does Scholar have the same home directory as other clusters?

The Scholar home directory and its contents are exclusive to Scholar cluster front-end hosts and compute nodes. This home directory is not available on other RCAC machines but Scholar. There is no automatic copying or synchronization between home directories.

At your discretion you can manually copy all or parts of your main research computing home to Scholar using one of the suggested methods.

If you plan to use hsi or htar commands to access Fortress tape archive from Scholar, please see also the keytab generation question for a temporary workaround to a potential caveat, while a permanent mitigation is being developed.
