 +====== Computing Information ======
 +
 +These pages have information on the computing services and [[compute_resources|resources]] provided by the UVA Computer Science Department.
 +
 +Computing services and resources are accessed via a CS Dept computing account. Faculty and graduate students have accounts created for them, undergraduates majoring in CS or taking CS courses can request a CS account.
 +
 +When you start at UVA, you get a userid (something like "//abc1de//"), which you use to access general UVA sites like Collab or NetBadge systems. When you get a CS Dept. account, you will have an identical userid ("//abc1de//"), //but a different password than the one you use for general UVA systems//. **When the CS account is created for you, you are sent an email with a temporary password that needs to be changed upon first login.** See //Account Information// below.
 +
 +----
 +==== Spring 2024 Updates ====
 +  * We have added a new server //serval01// to the SLURM job queue. It hosts 4 x H100 GPUs and 2TB of RAM. The GPUs have 80GB of memory, linked via Nvidia's Redstone SXM, so a total of 320GB of GPU memory can be addressed.
 +  
 +  * We have added a server for testing **Apptainer** software in the CS environment. The server is named %%''apptainer01''%% and is accessible using your CS login via SSH from portal. Please send feedback to //cshelpdesk@virginia.edu//. [[ https://apptainer.org/docs/user/main/ | Apptainer Usage Guide ]].

 +
 +===== Popular Information =====
 +==== CS Account Password Reset ====
 +**Reset your Computer Science Department account password:** Use the [[https://www.cs.virginia.edu/PasswordReset|Password Reset Tool]] 
 +
 +(New account users cannot use the password reset tool until they change their temporary password. See //Account Information// below.)
 +
 +==== Server Software ====
 +**Most common Linux software is already available on our systems! There is no need to install it.** See [[Linux_Environment_Modules|Software Modules]] for more information.
 +
 +==== Papercut Printing ====
 +Due to changes in Microsoft server, many Windows 11 laptops and desktops will no longer be able to print via our print server. To address this, we have deployed a solution called "papercut" that will help ease things.
 +
 +Simply go to: [[ http://printserver02.cs.virginia.edu:9163/setup/ | Papercut server ]]
 +
 +You should be able to install and select printers following the prompts!
 +
 +==== Account Information ====
 +
 +Faculty and graduate students have Computer Science (CS) accounts created for them, undergraduates in CS or Computer Engineering (CPE) or taking CS courses can request an account by sending an email to ''%%cshelpdesk@virginia.edu%%''.
 +
 +When your account for the Computer Science network has been created, you will be emailed the account information. Welcome!  
 +
 +Your account is for logging into servers and desktops within the CS Dept. It is NOT for CS websites or general UVA systems like Collab or other general UVA systems. Even though your user id is the same as your NetBadge user id used for UVA systems, //your CS account password is only for CS Dept. servers and desktop systems//.
 +
 +New accounts are assigned a temporary password, so the first time you log in you will be asked to set a new password. The ONLY way to change your temporary password is to open a “terminal” window on your laptop or desktop, and use //ssh// to //portal.cs.virginia.edu//, for example “''//ssh abc1de@portal.cs.virginia.edu//''”. You will then be asked for a new password, which you should set to a password you typically use. You will then use this password to login to all CS network systems. See [[linux_ssh_access|Linux SSH Access]] for more information. You cannot use the Password Reset tool link above to change your temporary password.
 +
 +Note: if you want to use a Linux remote desktop, (see: [[nx_lab|Nomachine Remote Desktop Sessions]]) you should FIRST login to //portal// to change your temporary password. The Linux remote desktop system will not let you login with that temporary password.
 +
 +If you forget your CS password you can reset it using the [[https://www.cs.virginia.edu/PasswordReset|Password Reset Tool]].
 +
 +Upon separation from UVA CS, your account will be closed one month after that separation, and your home directory will be removed. No backup will be provided, so it is important for you to save any files you wish to take with you onto other storage.

 +==== Regular accounts vs. mysql accounts ====
 +Please view this video for important information about mysql accounts. One thing not mentioned in the video is that your regular account and your mysql account are two different accounts with two different initial passwords, keep that in mind!\\

 +===== Using the CS Dept computing environment =====
 +
 +The CS Dept provides extensive computing resources. The entry point these resources is the [[compute_portal|portal]] cluster, a load balanced cluster of systems providing general purpose computing. From portal, [[compute_resources|other servers are available]] that have GPU accelerators, large memory sizes, and large core counts.
