Please also be aware that servers with hundreds of gigabytes of RAM are very expensive.  If you submit a job to the ''bigmem'' partition and your group does not have an NCU allocation sufficient to accommodate the resource request, your job will be rejected.

The big memory machines are available only via the HiPerGator "bigmem" partition. To submit jobs to this partition you will need to add the following directive to your job submission script.

 #SBATCH --partition=bigmem

Since our regular nodes have 1TB of available memory we do not recommend using bigmem nodes for jobs with memory requests lower than that.
