-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.+[[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 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.  (Information about SLURM and its use is available at https://howto.cs.uchicago.edu/techstaff:slurm.)   +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.

 Create a directory within /local on the system that you are using for data files that are large or will be accessed regularly by a program.  Doing so will improve performance (local disk is much faster than network disk) and will bypass home directory quotas. Create a directory within /local on the system that you are using for data files that are large or will be accessed regularly by a program.  Doing so will improve performance (local disk is much faster than network disk) and will bypass home directory quotas.
