-**Logging In**

-**Environmental Variables**
-To see the variables in your environment execute the command: env
-**Modules**
-The Environment Modules package provides for the dynamic modification of a user’s environment via modulefiles. To see available modules type the command

-**Submitting a Job**
-The cluster uses [[http://www.schedmd.com|SLURM]] for scheduling and resource management. Key commands to view the status of the cluster are
-**sinfo** reports the state of partitions and nodes managed by SLURM. It has a wide variety of filtering, sorting, and formatting options
-**squeue** reports the state of jobs or job steps. It has a wide variety of filtering, sorting, and formatting options. By default, it reports the running jobs in priority order and then the pending jobs in priority order.
-**srun** is used to submit a job for execution or initiate job steps in real time. srun has a wide variety of options to specify resource requirements, including: minimum and maximum node count, processor count, specific nodes to use or not use, and specific node characteristics (so much memory, disk space, certain required features, etc.). A job can contain multiple job steps executing sequentially or in parallel on independent or shared nodes within the job's node allocation.
-**sbatch** is used to submit a job script for later execution. The script will typically contain one or more srun commands to launch parallel tasks.
-**scancel** is used to cancel a pending or running job or job step. It can also be used to send an arbitrary signal to all processes associated with a running job or job step.
