Beartooth's "non-investor" partition
- TLBrewer
Beartooth has a special partition called “non-investor” that functions a little differently than other partitions. Rather than being based on a specific hardware set or level of investment, the non-investor partition lumps all community nodes into one partition.
A user job can request a particular partition by specifying the name of a partition in its job sbatch submission script with #SBATCH --partition=<partition_name> option. In this case: #SBATCH --partition=non-investor.
Pros:
Jobs cannot be preempted by investors.
Cons:
Some node types may not be available. There are some nodes that are present in Beartooth only because a researcher purchased them and generously allowed others to use those nodes when they are not.
The total number of available nodes (currently 282) is greatly reduced compared to the cluster as a whole. This can greatly increase a job’s queue time, depending on current demand.
