+ | ===Running Jobs=== | ||
+ | ALL jobs are required to be submitted to compute nodes thru use of the SLURM Job Scheduler. Running computationally intensive tasks (or memory intensive tasks) on the login nodes is prohibited. Such jobs will be killed by administrators. | ||

* **Himem Queues** - Don't submit jobs to this queue unless you truly need greater than 192GB of memory. If unsure, first test on a Comp queue to see if your task runs out of memory before migrating to the Himem queues. | * **Himem Queues** - Don't submit jobs to this queue unless you truly need greater than 192GB of memory.

+ | ===Interactive Jobs=== | ||
+ | HPC Clusters like Pinnacle aren't ideally suited for interactive jobs (srun) where constant user attention is required. Please be mindful when running these interactive jobs that, when the resource is not being used, cancel the session so that others may utilize the resources until you need it again. Leaving these sessions running idle and unattended is strongly discouraged. | ||
+ | |||
+ | ===User Assistance=== | ||
+ | For inquiries about software installations, | ||
+ | * Location of job script on system | ||
+ | * A copy of the .out or .err file from SLURM | ||
+ | * Any additional bits of information that might help | ||
+ | * Specific link to software you wish to have installed | ||
+ | |||
+ | |||
+ | ===System Utilization=== | ||
+ | Users should be conscientious when submitting lots of jobs to the system. Remember, you are sharing the resource with up to 800 other users! While SLURM Job Scheduler parameters typically manage workflow for the system, it is considered bad etiquette to try and submit as many jobs (packing the system) as the resource will allow, or occupying all of a particular resource type (such as Himem or GPU nodes).
