 +====Onsite Apps Required for COVID-19 Safety Compliance==== 
 +Techstaff has produced two applications to comply with the university's COVID-19 protocols. 
 + 
 +The first is a scheduling calendar that can be accessed at [[https://desks.cs.uchicago.edu/2020]].  It allows people to reserve space and records occupancy statistics.  Instructions are at the top of the webpage.  **You must use the calendar to reserve a block of time in a room in JCL //prior// to entering the building.** 
 + 
 +The second is a contact tracking app that can be accessed at [[https://contact.cs.uchicago.edu]].  You must use this application whenever you enter or leave a room within JCL.  The application records your cnetid, the room you are entering or leaving, and timestamps.  Its purpose is to aid with contract tracing in the event that someone visiting the building becomes ill with COVID-19. 
 + 
 +Short instructions: 
 + 
 +  * enter URL into your browser 
 +  * you will be prompted for cnetid and password. 
 +  * prior to entering a room, find the QR code posted on the door, click "check in" and a camera will activate. 
 +  * point the camera at the QR code for enter and the application will notify you that you are checked in. 
 +  * when you leave a room, you can select checkout for that room.

-[[techstaff:remote_access|Techstaff has 3 servers (linux1, linux2, and linux3)]] that serve as interactive login systems for instructional use.  These systems are reachable either by the canonical address or by a cname (linux.cs.uchicago.edu).  The address linux.cs.uchicago.edu is a DNS round-robin entry that will rotate between the canonical addresses.  This allows for future expansion of the service.  You should always be aware of the canonical in case you need to reconnect to a specific machine.  The canonical name is displayed in the shell prompt or can be found by typing the 'hostname' command.+[[techstaff:remote_access|Techstaff has 5 servers (linux1 through linux5)]] that serve as interactive login systems for instructional use.  These systems are reachable either by the canonical address or by a cname (linux.cs.uchicago.edu).  The address linux.cs.uchicago.edu is a DNS round-robin entry that will rotate between the canonical addresses.  This allows for future expansion of the service.  You should always be aware of the canonical in case you need to reconnect to a specific machine.  The canonical name is displayed in the shell prompt or can be found by typing the 'hostname' command.

 The [[techstaff:slurm|SLURM cluster]] was originally constructed to support Hank Hoffmann’s OS course.  SLURM is a job scheduling system that allows users to submit requests for resources and allows them to execute jobs using those reserved resources.   The [[techstaff:slurm|SLURM cluster]] was originally constructed to support Hank Hoffmann’s OS course.  SLURM is a job scheduling system that allows users to submit requests for resources and allows them to execute jobs using those reserved resources.  
 The cluster should be used for larger jobs, rather than than linux.cs.uchicago.edu. Additionally, we have a couple of GPUs that can be utilized on the cluster. The cluster should be used for larger jobs, rather than than linux.cs.uchicago.edu.
