Job Limits
Each LC platform is a shared resource. Users are expected to adhere to the following usage policies to ensure that the resources can be effectively and productively used by everyone. You can view the policies on a system itself by running:

Web version of Borax Job Limits
Borax is an M&IC resource to be used for serial and on-node parallelism only. Jobs are scheduled per core. This system does not have a high-speed interconnect.
Hardware
Each Borax node contains dual-socket Intel Broadwell processors (2.1 GHz) each with 18 cores for a total of 36 cores/node and 128 GiB memory/node.
Scheduling
Batch jobs are scheduled through SLURM.
- Interactive login: borax[2,5]
- Pdebug: borax[6-8]
- Batch use: borax[9-48]
Maximum memory size and duration of jobs on Borax
--------------------------------------------------------------- INTERACTIVE BATCH MEMORY CPU MEMORY CPU borax[2,5] 128 GiB 30 min - Interactive Only - borax[6-8] (pdebug) 128 GiB 30 min - Interactive Only - borax{9-48](pbatch) - Batch Only - 128 GiB 200 hrs ---------------------------------------------------------------
Pdebug is intended for debugging, visualization, and other inherently interactive work. It is NOT intended for production work. Do not use pdebug to run batch jobs. Do not chain jobs to run one after the other. Individuals who misuse the pdebug queue in this or any similar manner will be denied access to running jobs in the pdebug queue.
Interactive access to a batch node is allowed only while you have a batch job running on that node, and only for the purpose of monitoring your job. When logging into a batch node, be mindful of the impact your work has on the other jobs running on the node.
Multiple users can run on the same node. If the number of cores is not specified, the job is allocated to one core. Use the following syntax in your batch script to specify the actual number of cores needed:
SBATCH SCRIPT: #SBATCH -n number_of_cores
ALWAYS use the sbatch -n option when your job will use more than one task.
